CHANGELOG

All notable changes to this project will be documented in this file.

See the Changesets for the latest changes.

1.9.0 - 2026-03-07

Fixed

Fix issue where studio shows malformed color semantic token with token name

Added

Add support for *Css prop convention in JSX components.

Any JSX prop ending with Css (camelCase, e.g. inputCss, wrapperCss) is now treated as a style prop during static extraction, enabling compound component patterns like:

function Comp(props) {
  const { inputCss, wrapperCss, children } = props
  return (
    <styled.div css={wrapperCss}>
      <styled.input css={inputCss} />
      {children}
    </styled.div>
  )
}

// Usage - styles are statically extracted
const usage = <Comp inputCss={{ color: 'red.200' }} wrapperCss={{ display: 'flex' }} />

This works in both all and minimal JSX style prop modes, with no configuration needed.

1.8.2 - 2026-02-14

Fixed

Fix condition order when combining mixed conditions (array format) with nested selectors.

When using conditions like hover: ['&:hover'] with nested selectors like '& > :where(svg)', the CSS selector order was incorrect:

// Before (broken):
// .class > :where(svg):hover - hover applied to svg child

// After (fixed):
// .class:hover > :where(svg) - hover applied to parent element

The fix ensures that:

• At-rules are always placed first (for proper CSS wrapping)
• Selector conditions preserve their source order (matching what you write)

This affects users who define conditions using the array format and combine them with arbitrary/nested selectors.

Added

Add support for the experimental corner-shape CSS property, which specifies the shape of a box's corners. Valid values include: round, square, bevel, scoop, notch, squircle, and superellipse(<number>).

Changed

Update csstype from 3.1.3 to 3.2.3, which adds support for newer CSS properties including:

• Anchor positioning: anchorName, anchorScope, positionAnchor, positionArea, positionTry, positionTryFallbacks, positionTryOrder, positionVisibility
• Text wrapping: textWrapMode, textWrapStyle, textSpacingTrim
• Form sizing: fieldSizing, interpolateSize

1.8.1 - 2026-01-13

Changed

• System: Expanded TextStyleProperty type (used by TextStyle and TextStyles) to support new CSS text-box properties: text-box, text-box-edge, text-box-trim

1.8.0 - 2026-01-03

Added

• MCP Server (#mcp-new-tools)
  Added a new MCP server that exposes tools for AI agents.

  • New command: panda init-mcp
  • Available tools: get_tokens, get_semantic_tokens, get_recipes, get_patterns, get_conditions, get_text_styles, get_layer_styles, get_keyframes, get_config, get_usage_report

1.7.3 - 2026-01-02

Fixed

• Studio: Fixed React SSR errors when running Panda Studio.

  • ReferenceError: module is not defined—React's CJS entry point was loaded in an ESM context.
  • TypeError: dispatcher.getOwner is not a function—React development/production builds were mixed during SSR.

• Gradient Utilities: Fixed token() and brace syntax not working in bgGradient, bgLinear, and textGradient utilities.

  • Token references in gradient values now properly expand to CSS variables.
  • Both token() function syntax and brace syntax {...} now work correctly in gradient utilities.

1.7.2 - 2025-12-25

Fixed

• Studio: Fixed a crash on the colors page when using virtual semantic colors (for example, colors defined via a theme config).

• Node: Ensured ESM compatibility for @pandacss/node by converting p-limit and package-manager-detector imports to use dynamic import syntax.

1.7.1 - 2025-12-14

Fixed

• Config: Fix issue where @pandacss/config CJS entrypoint is broken due to merge-anything ESM-only dependency.

• Spec:

  • Fixed issue in recipe specs where boolean variant values were incorrectly formatted with quotes (e.g., button({ primary: true }) instead of button({ primary: 'true' })).
  • Updated color palette spec generation to dynamically discover and use actual available tokens

• Utility: Ensure the WebkitTextFillColor utility can accept color token values, like other color utilities.

1.7.0 - 2025-12-08

Added

• New panda spec Command: Introduced a panda spec command to generate specification files for your theme (helpful for documentation). This command outputs JSON spec files with metadata, examples, and usage information.

  • Usage:

    # Generate all spec files
    panda spec
    
    # Custom output directory
    panda spec --outdir custom/specs
    

  • Example structure:

    {
      "type": "tokens",
      "data": [
        {
          "type": "aspectRatios",
          "values": [{ "name": "square", "value": "1 / 1", "cssVar": "var(--aspect-ratios-square)" }],
          "tokenFunctionExamples": ["token('aspectRatios.square')"],
          "functionExamples": ["css({ aspectRatio: 'square' })"],
          "jsxExamples": ["<Box aspectRatio=\"square\" />"]
        }
      ]
    }
    

  • Example usage:

    import tokens from 'styled-system/specs/tokens'
    import recipes from 'styled-system/specs/recipes'
    

Fixed

• Static CSS Recipe Splitting: Fixed an issue where cssgen --splitting did not fully respect staticCss: { recipes: "*" }.
  • Global staticCss: { recipes: "*" } is now properly handled, even when individual recipes define their own staticCss property.
  • Split CSS generation now includes recipes with only base styles (no variants).

1.6.1 - 2025-12-03

Fixed

• css.raw Spreading: Fixed several scenarios where spreading css.raw objects wouldn't be properly extracted:

  Child selectors:

  const baseStyles = css.raw({ margin: 0, padding: 0 })
  const component = css({
    '& p': { ...baseStyles, fontSize: '1rem' }, // Now works
  })
  

  Nested conditions:

  const interactive = css.raw({ cursor: 'pointer', transition: 'all 0.2s' })
  const card = css({
    _hover: {
      ...interactive, // Now works
      _dark: { ...interactive, color: 'white' },
    },
  })
  

  CSS aliases:

  import { css as xcss } from 'styled-system/css'
  const styles = xcss.raw({ color: 'red' })
  // xcss.raw now properly recognized
  

1.6.0 - 2025-12-01

Added

• Add --splitting flag to cssgen command for per-layer CSS output.

When enabled, CSS is emitted as separate files instead of a single styles.css:

styled-system/
├── styles.css              # @layer declaration + @imports
└── styles/
    ├── reset.css           # Preflight/reset CSS
    ├── global.css          # Global CSS
    ├── tokens.css          # Design tokens
    ├── utilities.css       # Utility classes
    ├── recipes/
    │   ├── index.css       # @imports all recipe files
    │   └── {recipe}.css    # Individual recipe styles
    └── themes/
        └── {theme}.css     # Theme tokens (not auto-imported)

Usage:

panda cssgen --splitting

Fixed

• Studio

  • Fix semantic tokens defined in defineTheme not showing in Panda Studio. We now show a theme selector in the token pages for the theme-aware tokens.

  • Improve performance when searching for tokens.

1.5.1 - 2025-11-14

Fixed

• Style Context (Solid.js): Fixed defaultProps to allow Accessor types, enabling reactive default props in Solid.js components

• Style Context

  • Improved error messages for createStyleContext to include component name, slot, and recipe name when Provider is missing, making debugging easier
  • Fixed TypeScript types for withProvider and withContext to include the as prop, matching the behavior of the styled factory

Changed

• Open Props Preset: Updated to include new gradients, borders, and keyframe animations from the latest Open Props release

1.5.0 - 2025-11-09

Fixed

Fix TypeScript error when using data-* attributes in defaultProps for createStyleContext and JSX factory functions.

const TabsList = withContext(TabsPrimitive.List, 'list', {
  defaultProps: {
    'data-slot': 'tabs-list', // now works without type errors
  },
})

Changed

Update the experimental atlaskit preset with comprehensive token coverage from Atlassian Design System

New Token Categories

• Opacity tokens - disabled (0.4) and loading (0.2) semantic opacity values
• Duration tokens - Animation durations from @atlaskit/motion (none, small, medium, large)
• Easing tokens - Cubic-bezier curves from @atlaskit/motion (7 variants: easeIn, easeOut, easeInOut, easeIn40Out, easeIn60Out, easeIn80Out, linear)
• TextStyles - Semantic typography presets combining font properties (heading.*, body.*, code, metric.*)

Added

• Add support for controlling the color palette generation via theme.colorPalette property.

// Disable color palette generation completely
export default defineConfig({
  theme: {
    colorPalette: {
      enabled: false,
    },
  },
})

// Include only specific colors
export default defineConfig({
  theme: {
    colorPalette: {
      include: ['gray', 'blue', 'red'],
    },
  },
})

// Exclude specific colors
export default defineConfig({
  theme: {
    colorPalette: {
      exclude: ['yellow', 'orange'],
    },
  },
})

• Add endLineNumber and endColumn fields to AST JSON output from panda debug command.

The *.ast.json files generated by panda debug now include complete position information for detected CSS usage locations. Previously, only start position (line and column) was exported. Now the output includes:

• line: Start line number
• column: Start column number
• endLineNumber: End line number (new)
• endColumn: End column number (new)

This provides complete span coverage for each detected node, making it easier to precisely locate CSS usage in source files.

1.4.3 - 2025-10-18

Fixed

• Fix "Browserslist: caniuse-lite is outdated" warning by updating browserslist and PostCSS-related packages:

  • Update browserslist from 4.23.3 to 4.24.4
  • Update postcss from 8.4.49 to 8.5.6
  • Update postcss-nested from 6.0.1 to 7.0.2
  • Update postcss-merge-rules from 7.0.4 to 7.0.6
  • Update other PostCSS plugins to latest patch versions

  This resolves the outdated caniuse-lite warning that appeared when using lightningcss without affecting CSS output or requiring snapshot updates.

• Fix Cannot find module '@pandacss/preset-base' error when using Bun or other package managers that use flat node_modules structures.

• Style Context (Solid) Fix issue where withProvider does not properly provide context leading to runtime errors when wrapping headless component libraries like Ark UI.

Changed

• Style Context (Solid) Refactor withProvider and withContext types to ensure required props are properly extracted from the component props.
• Improve static CSS generation performance with wildcard memoization. Token lookups for wildcard (*) expansions are now cached, providing ~32% faster processing for large configs with wildcards.

1.4.2 - 2025-10-12

Fixed

• Fix issue where create-recipe.mjs helper was not generated when adding the first recipe to a project that previously had no recipes.
• Fix issue where using token() or token.var() function from styled-system/tokens doesn't get resolved by the compiler.

import { token } from 'styled-system/tokens'
import { css } from 'styled-system/css'

css({
  // This didn't work before, but now it does
  outline: `2px solid ${token('colors.gray.500')}`,

  // This has always worked
  outline: `2px solid token('colors.gray.500')`,
})

This also supports fallback values.

css({
  color: token('colors.brand.primary', '#3b82f6'),
})

Changed

Only log errors that are instances of PandaError, preventing test framework and other non-Panda errors from being logged during development.

1.4.1 - 2025-09-29

• JSX Recipe Tracking: Improve recipe variant props tracking in JSX by always tracking the <component>.Root for slot recipes.

1.4.0 - 2025-09-25

Added

• Preset Panda: Add 5.5 to spacing scale to cover more minor scales

Changed

• Preset Base: Change default spacing for stack and grid patterns from 10px to 8px

Fixed

• JSX Recipe Tracking: Always track the <component>.Root for recipe variant props. This is a generally resilient default and prevents the need for manual jsx hints.

• Preset Base: Fix regression in _marker condition due to the use of :is() which doesn't work for pseudo elements.

1.3.1 - 2025-09-18

Fixed

• JSX Style Context

  • Fix type issue where withRootProvider from style context incorrectly allowed JSX style props to be passed through to the root component.

  • Fix issue where defaultProps was not supported in withRootProvider across all framework implementations (React, Preact, Vue, Solid).

    const RootProvider = withRootProvider(Component, {
      defaultProps: {
        className: 'root-provider',
        // other default props
      },
    })
    

  • Fix issue in React where combining wrapping a style context component with styled caused ref to be incorrectly typed.

• JSX Recipe Tracking: Fix issue where Panda eagerly tracks every JSX slot of a slot recipe when scanning for recipe props. For example, assume you have a tabs recipe with the following slots:

  <Tabs.Root>
    <Tabs.List>
      <Tabs.Trigger />
    </Tabs.List>
    <Tabs.Content />
  </Tabs.Root>
  

  Panda tracks recipe props in Tabs.Root, Tabs.List, Tabs.Trigger, and Tabs.Content. This can lead to slightly more works in the compiler. Now, Panda only tracks recipe props in the Tabs.Root slot.

1.3.0 - 2025-09-10

Added

• LLM Text Support: The Panda docs now has support for llms.txt standard, making the documentation accessible and optimized for AI agents as Cursor, GitHub Copilot, ChatGPT, Perplexity, and Anthropic’s Claude.

• Transition Utilities: Added new transition values and enhanced transition property utilities in @pandacss/preset-base

  • size → width, height, min-width, max-width, min-height, max-height
  • position → left, right, top, bottom, inset, inset-inline, inset-block
  • background → background, background-color, background-image, background-position

• Composition Types: Add more properties to the textStyles and layerStyles config

  • Added text style properties: color, text layout (direction, textAlign, writingMode), and advanced text properties
  • Added layer style properties: layout (position, zIndex, display), visual effects (clipPath, mixBlendMode), and modern properties (aspectRatio, objectFit)

• JSX Polymorphic Support: Added as prop to JSX types for basic polymorphic component support. We don't infer the type of the target element.

Fixed

• Style Context: Fixed TypeScript types for defaultProps in withProvider and withContext to be partial in @pandacss/generator

• JSX Factory: Fixed issue where specifying defaultProps.children in styled or createStyleContext factories prevented overriding children in @pandacss/generator

1.2.0 - 2025-08-27

Added

• Global CSS: Added reset styles for ::selection pseudo element that maps to --global-color-selection css variable. You can configure it in the globalCss config.

  // panda.config.ts
  export default defineConfig({
    globalCss: {
      html: {
        '--global-color-selection': 'colors.gray.300',
      },
    },
  })
  

• JSX Styled Factory: Added support for unstyled prop in the styled factory, allowing users to opt out of recipe styles as needed.

  const Notice = styled('div', {
    base: {
      bg: 'red',
      color: 'white',
    },
  })
  
  // This will remove the recipe styles and only apply the inline styles
  <Notice unstyled bg="pink" color="green">
    Hello
  </Notice>
  

• Focus Ring Utilities: Introduced new utilities for managing focus rings with focusRing and focusVisibleRing properties to the @pandacss/preset-base preset.

  <div
    className={css({
      focusRing: 'outside',
      focusVisibleRing: 'inside',
      focusRingColor: 'blue.300',
    })}
  >
    Click me
  </div>
  

  • focusRing: Style focus states using &:is(:focus, [data-focus]) selector with outside, inside, mixed, or none values.
  • focusVisibleRing: Style keyboard-only focus using &:is(:focus-visible, [data-focus-visible]) selector
  • focusRingColor, focusRingWidth, focusRingStyle, and focusRingOffset for fine-tuned control
  • Configure the global focus ring color with --global-color-focus-ring in global CSS

• Theme: Add 4.5 spacing and sizing tokens to the @pandacss/preset-panda preset.

1.1.0 - 2025-08-18

Added

• Add support for preset:resolved hook to pick/omit specific preset properties.

  import { defineConfig } from '@pandacss/dev'
  
  export default defineConfig({
    // ...
    hooks: {
      'preset:resolved': ({ utils, preset, name }) => {
        if (name === '@pandacss/preset-panda') {
          return utils.omit(preset, ['theme.tokens.colors', 'theme.semanticTokens.colors'])
        }
        return preset
      },
    },
  })
  

• Add missing WebKit CSS properties to resolve TypeScript errors. Adds support for:

  • WebkitUserDrag / -webkit-user-drag - Controls element drag behavior
  • WebkitAppRegion / -webkit-app-region - For Electron window controls
  • WebkitBorderHorizontalSpacing / -webkit-border-horizontal-spacing - Table border spacing
  • WebkitBorderVerticalSpacing / -webkit-border-vertical-spacing - Table border spacing
  • WebkitTextSecurity / -webkit-text-security - Text obscuring for passwords

Fixed

• Fixes TypeScript errors when using vendor-prefixed properties in Panda CSS.

1.0.1 - 2025-08-05

Fixed

• createStyleContext: Ensure the defaultProps.className is applied correctly when no explicit class prop is provided
• Fix issue where bgGradient did not respect the gradient token.

1.0.0 - 2025-08-04

Fixed

• Fix issue where rtl and ltr variants does not work with [dir=auto]
• Fix issue where @property fallbacks does not work correctly when global vars are used in no initial-value
• Sort fieldSizing property properly

Changed

• Add ::-webkit-details-marker to marker condition
• Add new inset-2xs, inset-xs and inset-sm shadows
• Add new noscript and inverted-colors conditions
• Add :popover-open to open condition
• Removed inner shadow in favor of inset-sm
• Remap blur tokens:
  • blurs.sm -> blurs.xs
  • blurs.base -> blurs.sm

Added

• Add support for bgLinear, bgRadial and bgConic properties.

<div
  className={css({
    bgLinear: 'to-r',
    gradientFrom: 'cyan.500',
    gradientTo: 'blue.500',
  })}
/>

<div
  className={css({
    bgRadial: 'in srgb',
    gradientFrom: 'pink.400',
    gradientFromPosition: '40%',
    gradientTo: 'fuchsia.700',
  })}
/>

<div
  className={css({
    bgConic: 'in srgb',
    gradientFrom: 'blue.600',
    gradientTo: 'sky.400',
    gradientToPosition: '50%',
  })}
/>

• Add support for boxSize property that maps to width and height properties.

<div className={css({ boxSize: '24' })} />

• Add createStyleContext function to framework artifacts for React, Preact, Solid, and Vue frameworks

import { sva } from 'styled-system/css'
import { createStyleContext } from 'styled-system/jsx'

const card = sva({
  slots: ['root', 'label'],
  base: {
    root: {
      color: 'red',
      bg: 'red.300',
    },
    label: {
      fontWeight: 'medium',
    },
  },
  variants: {
    size: {
      sm: {
        root: {
          padding: '10px',
        },
      },
      md: {
        root: {
          padding: '20px',
        },
      },
    },
  },
  defaultVariants: {
    size: 'sm',
  },
})

const { withProvider, withContext } = createStyleContext(card)

const CardRoot = withProvider('div', 'root')
const CardLabel = withContext('label', 'label')

Then, use like this:

<CardRoot size="sm">
  <CardLabel>Hello</CardLabel>
</CardRoot>

0.54.0 - 2025-06-12

Fixed

• Fix issue where borderWidth token reference adds an extra px to the generated css value
• Fix TS generated pattern dts code when strict: true is set
• Fix issue where text (or layer) styles that use conditions don't render correctly
• Revert tinyglobally to fast-glob change to fix issues with glob matching

Added

• Add more aria attributes to conditions for better accessibility and styling hooks:
  • [aria-disabled=true] was added to disabled, peerDisabled, and groupDisabled conditions
  • [aria-readonly=true] was added to the readOnly condition
  • [aria-invalid=true] was added to invalid and groupInvalid conditions

Changed

• Improve algorithm for deterministic property order:

  • Longhand (padding, margin, inset)
  • Shorthand of longhands (padding-inline, margin-inline)
  • Shorthand of shorthands (padding-inline-start, margin-inline-start)

  css({
    p: '4',
    pr: '2',
    px: '10',
  })
  

  Will result in the following css regardless of the order of the properties:

  .p-4 {
    padding: 4px;
  }
  
  .px-10 {
    padding-left: 10px;
    padding-right: 10px;
  }
  
  .pr-2 {
    padding-right: 2px;
  }
  

• Reduce the size of the generated Token type by referencing category tokens

  Before:

  export type Token = 'colors.green.400' | 'colors.red.400'
  
  export type ColorToken = 'green.400' | 'red.400'
  

  After:

  export type Token = `colors.${ColorToken}`
  
  export type ColorToken = 'green.400' | 'red.400'

╚════════════════════════╧════════════════╧═══════════════════╧═══════════════════╧══════════╧═══════════╝

Added

• Add support for panda analyze --output <file>.json to output the analysis results to a file.

0.51.0 - 2024-12-31

[BREAKING]: Fix issue where Next.js build might fail intermittently due to version mismatch between internal ts-morph and userland typescript.

0.50.0 - 2024-12-27

Added

• Add support for semantic tokens in composite shadow blur, offsetX, offsetY and spread properties.

This enables the use of semantic tokens in composite shadow properties.

// panda.config.ts

export default defineConfig({
  theme: {
    tokens: {
      // ...
      shadows: {
        sm: {
          value: {
            offsetX: '{spacing.3}',
            offsetY: '{spacing.3}',
            blur: '1rem',
            spread: '{spacing.3}',
            color: '{colors.red}',
          },
        },
      },
    },
  },
})

• Adds support for static analysis of used tokens and recipe variants. It helps to get a birds-eye view of how your design system is used and answers the following questions:

• What tokens are most used?

• What recipe variants are most used?

• How many hardcoded values vs tokens do we have?

panda analyze --scope=<token|recipe>

Still work in progress but we're excited to get your feedback!

Changed

Improve inference of slots in slot recipes when spreading and concatenating slot names.

This handles the following case gracefully:

const styles = sva({
  className: 'foo',
  slots: [...componentAnatomy.keys(), 'additional', 'slots', 'here'],
})

Panda will now infer the slots from the anatomy and add them to the recipe.

0.49.0 - 2024-12-08

Add support for animation styles. Animation styles focus solely on animations, allowing you to orchestrate animation properties.

Pairing animation styles with text styles and layer styles can make your styles a lot cleaner.

Here's an example of this:

import { defineAnimationStyles } from '@pandacss/dev'

export const animationStyles = defineAnimationStyles({
  'slide-fade-in': {
    value: {
      transformOrigin: 'var(--transform-origin)',
      animationDuration: 'fast',
      '&[data-placement^=top]': {
        animationName: 'slide-from-top, fade-in',
      },
      '&[data-placement^=bottom]': {
        animationName: 'slide-from-bottom, fade-in',
      },
      '&[data-placement^=left]': {
        animationName: 'slide-from-left, fade-in',
      },
      '&[data-placement^=right]': {
        animationName: 'slide-from-right, fade-in',
      },
    },
  },
})

With that defined, I can use it in my recipe or css like so:

export const popoverSlotRecipe = defineSlotRecipe({
  slots: anatomy.keys(),
  base: {
    content: {
      _open: {
        animationStyle: 'scale-fade-in',
      },
      _closed: {
        animationStyle: 'scale-fade-out',
      },
    },
  },
})

This feature will drive consumers to lean in towards CSS for animations rather than JS. Composing animation names is a powerful feature we should encourage consumers to use.

Added

0.48.1 - 2024-12-07

Fixed

• Fix issue where staticCss artifacts were not included in the build info json.
• Fix issue where scrollbarGutter property incorrectly referenced spacing tokens. The only valid values are auto, stable, and both-edges.

0.48.0 - 2024-11-13

Fixed

Fix multi-theme issue where calling the getTheme function throws a Vite error due to invalid dynamic import format.

import { getTheme } from 'styled-system/themes'

getTheme('default')
// -> The above dynamic import cannot be analyzed by Vite.

Changed

[Breaking] Remove default utility values for gridTemplateColumns, gridTemplateRows, gridColumn and gridRow to prevent interference with native css values.

For example 1 or 2 is a valid native value for gridColumn or gridRow, and should not be overridden by the utility.

Find the previous default values below, you can add them back to your config if you need them.

const utilities = {
  gridTemplateColumns: {
    className: 'grid-tc',
    group: 'Grid Layout',
    values: {
      '1': 'repeat(1, minmax(0, 1fr))',

      '4': 'span 4 / span 4',
      '5': 'span 5 / span 5',
      '6': 'span 6 / span 6',
      '7': 'span 7 / span 7',
      '8': 'span 8 / span 8',
      '9': 'span 9 / span 9',
      '10': 'span 10 / span 10',
      '11': 'span 11 / span 11',
      '12': 'span 12 / span 12',

      '11': 'span 11 / span 11',
      '12': 'span 12 / span 12',
    },
  },
}

0.47.1 - 2024-11-06

Fixed

• Fix postcss; race condition on builder instance for simultaneous plugin invocations
• Fix issue where token reference in composite border token generates incorrect css.

0.47.0 - 2024-10-18

Added

Add support for cursor token types. Useful for tokenizing cursor types for interactive components.

Here's an example of how to define a cursor token in your panda.config.ts file:

// panda.config.ts
export default defineConfig({
  theme: {
    extend: {
      tokens: {
        cursor: {
          button: { value: 'pointer' },
          checkbox: { value: 'default' },
        },
      },
    },
  },
})

Then you can use the cursor token in your styles or recipes.

<button className={css({ cursor: 'button' })}>Click me</button>

This makes it easy to manage cursor styles across your application.

Changed

Improve preflight css such that elements with hidden=until-found are visible. Previously, we always hide all elements with the hidden attribute

0.46.1 - 2024-09-09

Fixed

Fix issue where using container query in static css results in empty styles.

0.46.0 - 2024-09-09

Fixed

• Fix: use sizing tokens for flexBasis instead of spacing tokens
• Fix issue where nesting @scope rule that use the & don't expand correctly

Added

Add support native css nesting in template literal mode. Prior to this change, you need to add & to all nested selectors.

Before:

css`
  & p {
    color: red;
  }
`

After:

css`
  p {
    color: red;
  }
`

Good to know: Internally, this will still convert to p to & p, but the generated css will work as expected.

0.45.2 - 2024-08-29

Changed

Make WithEscapeHatch<T> much more performant and typescript happy by updating the type signature of WithImportant<T> and WithColorOpacityModifier<T> to use branded type and non-distributive conditional types, while keeping such tokens valid and also not appearing in autocompletions to prevent them from polluting autocompletion result (which is the current behavior).

0.45.1 - 2024-08-14

Fixed

Fix issue where shadow token with color opacity modifier produces incorrect css value

Changed

[Internal] switch to package-manager-detector to reduce dependencies

0.45.0 - 2024-08-06

Fixed

• Fix issue where composite border token with width: 1px renders 1pxpx in CSS
• Fix issue where divideY and divideColor utilities, used together in a recipe, doesn't generate the correct css.

Added

Add support resolving DEFAULT in textStyles and layerStyles, just like tokens.

export default defineConfig({
  theme: {
    textStyles: {
      display: {
        // 'display'
        DEFAULT: {
          value: {
            fontSize: '1.5rem',
            fontWeight: 'bold',
          },
        },
        // 'display.large'
        large: {
          value: {
            fontSize: '2rem',
            fontWeight: 'bold',
          },
        },
      },
    },
  },
})

In case, you can use textStyles: display to reference the DEFAULT display value.

css({ textStyle: 'display' })

Changed

Remove base from css or pattern style objects. The base keyword is only supported in recipes or conditional styles.

Before

hstack({
  // ❌ doesn't work
  base: {
    background: 'red.400',
    p: '11',
  },
  display: 'flex',
  flexDirection: 'column',
})

After

hstack({
  // ✅ works
  background: 'red.400',
  p: '11',
  display: 'flex',
  flexDirection: 'column',
})

0.44.0 - 2024-07-22

Fixed

• Ensure globalFontface definitions are merged correctly

Added

• Add a name mandatory key in Preset to make it easy to target one specifically

Changed

• Replace JSX with React.JSX for better React 19 support

0.43.0 - 2024-07-19

Added

Add support for defining global font face in config and preset

// pandacss.config.js
export default defineConfig({
  globalFontface: {
    Roboto: {
      src: 'url(/fonts/roboto.woff2) format("woff2")',
      fontWeight: '400',
      fontStyle: 'normal',
    },
  },
})

You can also add multiple font src for the same weight

// pandacss.config.js

export default defineConfig({
  globalFontface: {
    Roboto: {
      // multiple src
      src: ['url(/fonts/roboto.woff2) format("woff2")', 'url(/fonts/roboto.woff) format("woff")'],
      fontWeight: '400',
      fontStyle: 'normal',
    },
  },
})

You can also define multiple font weights

// pandacss.config.js

export default defineConfig({
  globalFontface: {
    // multiple font weights
    Roboto: [
      {
        src: 'url(/fonts/roboto.woff2) format("woff2")',
        fontWeight: '400',
        fontStyle: 'normal',
      },
      {
        src: 'url(/fonts/roboto-bold.woff2) format("woff2")',
        fontWeight: '700',
        fontStyle: 'normal',
      },
    ],
  },
})

0.42.0 - 2024-07-08

Added

• Add support for 4xl border radius token

Changed

• Ensure classnames are unique across utilities to prevent potential clash
• Change recipes className to be optional, both for recipes and slotRecipes, with a fallback to its name.
• Minor changes to the format of the panda analyze --output coverage.json file

import { defineConfig } from '@pandacss/core'

export default defineConfig({
  recipes: {
    button: {
      className: 'button', // 👈 was mandatory, is now optional
      variants: {
        size: {
          sm: { padding: '2', borderRadius: 'sm' },
          md: { padding: '4', borderRadius: 'md' },
        },
      },
    },
  },
})

• [BREAKING] Removed the legacy config.optimize option because it was redundant. Now, we always optimize the generated CSS where possible.

• BREAKING: Remove emitPackage config option,

  tldr: use importMap instead for absolute paths (e.g can be used for component libraries)

  emitPackage is deprecated, it's known for causing several issues:

  • bundlers sometimes eagerly cache the node_modules, leading to panda codegen updates to the styled-system not visible in the browser
  • auto-imports are not suggested in your IDE.
  • in some IDE the typings are not always reflected properly

  As alternatives, you can use:

  • relative paths instead of absolute paths (e.g. ../styled-system/css instead of styled-system/css)
  • use package.json #imports and/or tsconfig path aliases (prefer package.json#imports when possible, TS 5.4 supports them by default) like #styled-system/css instead of styled-system/css https://nodejs.org/api/packages.html#subpath-imports
  • for a component library, use a dedicated workspace package (e.g. @acme/styled-system) and use importMap: "@acme/styled-system" so that Panda knows which entrypoint to extract, e.g. import { css } from '@acme/styled-system/css' https://panda-css.com/docs/guides/component-library

0.41.0 - 2024-06-16

Fixed

Fix an issue where spreading an identifier in a sva slots array would prevent expected CSS from being generated

import { sva } from 'styled-system/css'
const parts = ['positioner', 'content']

const card = sva({
  slots: [...parts], // <- spreading here was causing the below CSS not to be generated, it's now fixed ✅
  base: {
    root: {
      p: '6',
    },
  },
})

Added

Annotate config recipe default variants with the @default js doc comment. This makes it easy to know the default value of a variant.

0.40.1 - 2024-05-31

Fixed

• Fix issue where using jsxStyleProps: none with the generated jsx patterns, lead to unoptimized code that causes the component to be recreated on every render.

Changed

• Improve panda init --outdir=<x> command to reflect outdir in generated panda config file.

0.40.0 - 2024-05-29

Added

Improve monorepo setup DX by exposing some cli flags

panda init

• Added new flag --no-codegen to skip codegen during initialization
• Added new flag --outdir to specify the output directory for generated files

panda emit-pkg

• Added new --base flag to specify the base directory for the entrypoints in the generated package.json#exports field

0.39.2 - 2024-05-25

Fixed

• Vue JSX: Fix issue where using custom jsxFactory name causes a runtime error
• Fix issue where panda could load unrelated config files that look like a config e.g. theming-panda.config.ts
• Fix a cache issue that leads to HMR growing slower in some cases
• Fix an issue where using CSS var in the token references fallback argument would be escaped
• Fix panda analyze JSON output serialization

Added

• Allow nesting (string) token references in the fallback argument

0.39.1 - 2024-05-07

Fixed

Fix css.raw typings after recent (0.39.0) changes allowing arrays of SystemStyleObject

0.39.0 - 2024-04-29

Fixed

• Fix issue where mergeCss import in styled-system/jsx/* could be unused.
• Fix issue where float property did not allow inherited values (auto, initial, none, etc.)
• Fix issue where animationName property was not connected to theme.keyframes, as a result, no autocompletion was available.

Added

• Add support for more typography related properties in text styles such as fontFeatureSettings, fontPalette, etc.
• Allow passing arrays of SystemStyleObject to the css(xxx, [aaa, bbb, ccc], yyy) fn

This is useful when you are creating your own styled component and want to benefit from the recent css array property support.

import { css } from 'styled-system/css'
import type { HTMLStyledProps } from 'styled-system/types'

type ButtonProps = HTMLStyledProps<'button'>

export const Button = ({ css: cssProp = {}, children }: ButtonProps) => {
-  const className = css(...(Array.isArray(cssProp) ? cssProp : [cssProp]))
+  const className = css(cssProp)
  return <button className={className}>{children}</button>
}

Changed

• BREAKING 💥

Remove linkBox pattern in favor of using adding position: relative when using the linkOverlay pattern.

Before

import { linkBox, linkOverlay } from 'styled-system/patterns'

const App = () => {
  return (
    <div className={linkBox()}>
      <img src="https://via.placeholder.com/150" alt="placeholder" />
      <a href="#" className={linkOverlay()}>
        Link
      </a>
    </div>
  )
}

After

import { css } from 'styled-system/css'
import { linkOverlay } from 'styled-system/patterns'

const App = () => {
  return (
    <div className={css({ pos: 'relative' })}>
      <img src="https://via.placeholder.com/150" alt="placeholder" />
      <a href="#" className={linkOverlay()}>
        Link
      </a>
    </div>
  )
}

0.38.0 - 2024-04-29

Fixed

• Fix css reset regressions where:
  • first letter gets a different color
  • input or select gets a default border
• Fix type import
• Fix Panda imports detection when using tsconfig.baseUrl with an outdir that starts with ./.

Added

• Add least resource used (LRU) cache in the hot parts to prevent memory from growing infinitely
• Add support for deprecating tokens, utilities, patterns and config recipes.

Set the deprecated property to true to enable deprecation warnings. Alternatively, you can also set it to a string to provide a custom migration message.

Deprecating a utility

defineConfig({
  utilities: {
    ta: {
      deprecated: true,
      transform(value) {
        return { textAlign: value }
      },
    },
  },
})

Deprecating a token

defineConfig({
  theme: {
    tokens: {
      spacing: {
        lg: { value: '8px', deprecated: 'use `8` instead' },
      },
    },
  },
})

Deprecating a pattern

defineConfig({
  patterns: {
    customStack: {
      deprecated: true,
    },
  },
})

Deprecating a recipe

defineConfig({
  theme: {
    recipes: {
      btn: {
        deprecated: 'will be removed in v2.0',
      },
    },
  },
})

• Add support for array values in the special css property for the JSX factory and JSX patterns

This makes it even easier to merge styles from multiple sources.

import { Stack, styled } from '../styled-system/jsx'

const HeroSection = (props) => {
  return (
    <Stack css={[{ color: 'blue.300', padding: '4' }, props.css]}>
      <styled.div css={[{ fontSize: '2xl' }, props.hero]}>Hero Section</styled.div>
    </Stack>
  )
}

const App = () => {
  return (
    <>
      <HeroSection css={{ backgroundColor: 'yellow.300' }} hero={css.raw({ fontSize: '4xl', color: 'red.300' })} />
    </>
  )
}

should render something like:

<div class="d_flex flex_column gap_10px text_blue.300 p_4 bg_yellow.300">
  <div class="fs_4xl text_red.300">Hero Section</div>
</div>

0.37.2 - 2024-04-05

Fixed

• fix: build correct path for debug files on windows
• Add missing type PatternProperties to solve a TypeScript issue (The inferred type of xxx cannot be named without a reference)
• Fix sva typings, the splitVariantProps was missing from the d.ts file

Added

• Add a getVariantProps helper to the slot recipes API (sva and config slot recipes)

import { sva } from '../styled-system/css'
import { getVariantProps } from '../styled-system/recipes'

const button = sva({
  slots: ['root', 'icon'],
  // ...
  variants: {
    size: {
      sm: {
        // ...
      },
      md: {
        // ...
      },
    },
    variant: {
      primary: {
        // ...
      },
      danger: {
        // ...
      }
    }
  }
  defaultVariants: {
    size: 'md',
    variant: 'primary',
  }
})

// ✅ this will return the computed variants based on the defaultVariants + props passed
const buttonProps = button.getVariantProps({ size: "sm" })
//    ^? { size: "sm", variant: "primary" }

Changed

• Make WithImportant<T> more performant and ensure typescript is happy. This changes will make code autocompletion and ts-related linting much faster than before.

0.37.1 - 2024-04-02

Fixed

• Improve token validation logic to parse references in tokens and compositve values like borders and shadows which could be objects.
• Fix issue where setting the pattern jsx option with dot notation didn't work.

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  patterns: {
    extend: {
      grid: {
        jsx: ['Form.Group', 'Grid'],
      },
      stack: {
        jsx: ['Form.Action', 'Stack'],
      },
    },
  },
})

• Fix an issue where the compoundVariants classes would not be present at runtime when using config recipes

// panda.config.ts
import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  theme: {
    extend: {
      recipes: {
        button: {
          // ...
          variants: {
            size: {
              sm: {
                fontSize: 'sm',
              },
              // ...
            },
          },
          compoundVariants: [
            {
              size: 'sm',
              css: { color: 'blue.100'},
            },
          ],
        },
      },
    },
  },
})

// app.tsx
const Button = styled('button', button)

const App = () => {
  return (
    // ❌ this would only have the classes `button button--size_sm`
    // the `text_blue` was missing
    // ✅ it's now fixed -> `button button--size_sm text_blue`
    <Button size="sm">Click me</Button>
  )
}

Added

• Add a getVariantProps helper to the recipes API (cva and config recipes)

import { cva } from '../styled-system/css'
import { getVariantProps } from '../styled-system/recipes'

const button = cva({
    // ...
  variants: {
    size: {
      sm: {
        fontSize: 'sm',
      },
      md: {
        fontSize: 'md',
      },
    },
    variant: {
      primary: {
        backgroundColor: 'blue.500',
      },
      danger: {
        backgroundColor: 'red.500',
      }
    }
  }
  defaultVariants: {
    size: 'md',
    variant: 'primary',
  }
})

// ✅ this will return the computed variants based on the defaultVariants + props passed
const buttonProps = button.getVariantProps({ size: "sm" })
//    ^? { size: "sm", variant: "primary" }

Changed

Public changes: Some quality of life fixes for the Studio:

• Handle displaying values using the [xxx] escape-hatch syntax for textStyles in the studio
• Display an empty state when there's no token in a specific token page in the studio

(mostly) Internal changes:

• Add deepResolveReference in TokenDictionary, helpful to get the raw value from a semantic token by recursively traversing the token references.
• Added some exports in the @pandacss/token-dictionary package, mostly useful when building tooling around Panda (Prettier/ESLint/VSCode plugin etc)

0.37.0 - 2024-04-01

Fixed

• Fix className collisions between utilities by using unique class names per property in the default preset.

• Fix a bug where some styles would be grouped together in the same rule, even if they were not related to each other.

Internal details

This was caused by an object reference being re-used while setting a property deeply in the hashes decoding process, leading to the mutation of a previous style object with additional properties.

Added

• Add missing typings for CSS vars in properties bound to utilities (and that are not part of the list affected by strictPropertyValues)
• Allow multiple importMap (or multiple single import entrypoints if using the object format).

It can be useful to use a component library's styled-system while also using your own styled-system in your app.

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  importMap: ['@acme/styled-system', '@ui-lib/styled-system', 'styled-system'],
})

Now you can use any of the @acme/styled-system, @ui-lib/styled-system and styled-system import sources:

import { css } from '@acme/css'
import { css as uiCss } from '@ui-lib/styled-system/css'
import { css as appCss } from '@ui-lib/styled-system/css'

• Spacing Utilities: Add new spaceX and spaceY utilities for applying margin between elements. Especially useful when applying negative margin to child elements.

<div className={flex({ spaceX: '-1' })}>
  <div className={circle({ size: '5', bg: 'red' })} />
  <div className={circle({ size: '5', bg: 'pink' })} />
</div>

• Added new _starting condition to support the new @starting-style at-rule. Learn more here

• Gradient Position: Add new gradientFromPosition and gradientToPosition utilities for controlling the position of the gradient color stops.

<div
  className={css({
    bgGradient: 'to-r',
    // from
    gradientFrom: 'red',
    gradientFromPosition: 'top left',
    // to
    gradientTo: 'blue',
    gradientToPosition: 'bottom right',
  })}
/>

Changed

• Color Mode Selectors: Changed the default selectors for _light and _dark to target parent elements. This ensures consistent behavior with using these conditions to style pseudo elements (like ::before and ::after).

const conditions = {
-  _dark: '&.dark, .dark &',
+  _dark: '.dark &',
-  _light: '&.light, .light &',
+  _light: '.light &',
}

• Changed divideX and divideY now maps to the borderWidths token group.

0.36.1 - 2024-03-19

Fixed

• Fix theme variants typings
• Fix JSX matching with recipes after introducing namespace imports

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  theme: {
    extend: {
      slotRecipes: {
        tabs: {
          className: 'tabs',
          slots: ['root', 'list', 'trigger', 'content', 'indicator'],
          base: {
            root: {
              display: 'flex',
              // ...
            },
          },
        },
      },
    },
  },
})

const App = () => {
  return (
    // ❌ this was not matched to the `tabs` slot recipe
    // ✅ fixed with this PR
    <Tabs.Root defaultValue="button">
      <Tabs.List>
        <Tabs.Trigger value="button">Button</Tabs.Trigger>
        <Tabs.Trigger value="radio">Radio Group</Tabs.Trigger>
        <Tabs.Trigger value="slider">Slider</Tabs.Trigger>
        <Tabs.Indicator />
      </Tabs.List>
    </Tabs.Root>
  )
}

We introduced a bug in v0.34.2 where the Tabs.Trigger component was not being matched to the tabs slot recipe, due to the new namespace import feature.

0.36.0 - 2024-03-19

Fixed

• Fix Expression produces a union type that is too complex to represent with splitCssProps because of JsxStyleProps type

• Fix merging issue when using a preset that has a token with a conflicting value with another (or the user's config)

import { defineConfig } from '@pandacss/dev'

const userConfig = defineConfig({
  presets: [
    {
      theme: {
        extend: {
          tokens: {
            colors: {
              black: { value: 'black' },
            },
          },
        },
      },
    },
  ],
  theme: {
    tokens: {
      extend: {
        colors: {
          black: {
            0: { value: 'black' },
            10: { value: 'black/10' },
            20: { value: 'black/20' },
            30: { value: 'black/30' },
          },
        },
      },
    },
  },
})

When merged with the preset, the config would create nested tokens (black.10, black.20, black.30) inside of the initially flat black token.

This would cause issues as the token engine stops diving deeper after encountering an object with a value property.

To fix this, we now automatically replace the flat black token using the DEFAULT keyword when resolving the config so that the token engine can continue to dive deeper into the object:

{
  "theme": {
    "tokens": {
      "colors": {
        "black": {
          "0": {
            "value": "black",
          },
          "10": {
            "value": "black/10",
          },
          "20": {
            "value": "black/20",
          },
          "30": {
            "value": "black/30",
          },
-          "value": "black",
+          "DEFAULT": {
+            "value": "black",
+          },
        },
      },
    },
  },
}

• Fix an issue when using a semantic token with one (but not all) condition using the color opacity modifier

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  theme: {
    extend: {
      tokens: {
        colors: {
          black: { value: 'black' },
          white: { value: 'white' },
        },
      },
      semanticTokens: {
        colors: {
          fg: {
            value: {
              base: '{colors.black/87}',
              _dark: '{colors.white}', // <- this was causing a weird issue
            },
          },
        },
      },
    },
  },
})

• Fix strictPropertyValues typings should allow for CssVars (either predefined from globalVars or any custom CSS variable)

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  strictPropertyValues: true,
  globalVars: {
    extend: {
      '--some-color': 'red',
      '--button-color': {
        syntax: '<color>',
        inherits: false,
        initialValue: 'blue',
      },
    },
  },
})

css({
  // ❌ was not allowed before when `strictPropertyValues` was enabled
  display: 'var(--button-color)', // ✅ will now be allowed/suggested
})

If no globalVars are defined, any var(--*) will be allowed

css({
  // ✅ will be allowed
  display: 'var(--xxx)',
})

Added

• Introduce a new globalVars config option to define type-safe CSS variables and custom CSS @property.

Example:

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  globalVars: {
    '--some-color': 'red',
    '--button-color': {
      syntax: '<color>',
      inherits: false,
      initialValue: 'blue',
    },
  },
})

Note: Keys defined in globalVars will be available as a value for every utilities, as they're not bound to token categories.

import { css } from '../styled-system/css'

const className = css({
  '--button-color': 'colors.red.300',
  // ^^^^^^^^^^^^  will be suggested

  backgroundColor: 'var(--button-color)',
  //                ^^^^^^^^^^^^^^^^^^  will be suggested
})

• Add config.themes to easily define and apply a theme on multiple tokens at once, using data attributes and CSS variables.

Can pre-generate multiple themes with token overrides as static CSS, but also dynamically import and inject a theme stylesheet at runtime (browser or server).

Example:

// panda.config.ts
import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  // main theme
  theme: {
    extend: {
      tokens: {
        colors: {
          text: { value: 'blue' },
        },
      },
      semanticTokens: {
        colors: {
          body: {
            value: {
              base: '{colors.blue.600}',
              _osDark: '{colors.blue.400}',
            },
          },
        },
      },
    },
  },
  // alternative theme variants
  themes: {
    primary: {
      tokens: {
        colors: {
          text: { value: 'red' },
        },
      },
      semanticTokens: {
        colors: {
          muted: { value: '{colors.red.200}' },
          body: {
            value: {
              base: '{colors.red.600}',
              _osDark: '{colors.red.400}',
            },
          },
        },
      },
    },
    secondary: {
      tokens: {
        colors: {
          text: { value: 'blue' },
        },
      },
      semanticTokens: {
        colors: {
          muted: { value: '{colors.blue.200}' },
          body: {
            value: {
              base: '{colors.blue.600}',
              _osDark: '{colors.blue.400}',
            },
          },
        },
      },
    },
  },
})

Pregenerating themes

By default, no additional theme variant is generated, you need to specify the specific themes you want to generate in staticCss.themes to include them in the CSS output.

// panda.config.ts
import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  staticCss: {
    themes: ['primary', 'secondary'],
  },
})

This will generate the following CSS:

@layer tokens {
  :where(:root, :host) {
    --colors-text: blue;
    --colors-body: var(--colors-blue-600);
  }

  [data-panda-theme='primary'] {
    --colors-text: red;
    --colors-muted: var(--colors-red-200);
    --colors-body: var(--colors-red-600);
  }

  @media (prefers-color-scheme: dark) {
    :where(:root, :host) {
      --colors-body: var(--colors-blue-400);
    }

    [data-panda-theme='primary'] {
      --colors-body: var(--colors-red-400);
    }
  }
}

An alternative way of applying a theme is by using the new styled-system/themes entrypoint where you can import the themes CSS variables and use them in your app.

ℹ️ The styled-system/themes will always contain every themes (tree-shaken if not used), staticCss.themes only applies to the CSS output.

Each theme has a corresponding JSON file with a similar structure:

{
  "name": "primary",
  "id": "panda-themes-primary",
  "dataAttr": "primary",
  "css": "[data-panda-theme=primary] { ... }"
}

ℹ️ Note that for semantic tokens, you need to use inject the theme styles, see below

Dynamically import a theme using its name:

import { getTheme } from '../styled-system/themes'

const theme = await getTheme('red')
//    ^? {
//     name: "red";
//     id: string;
//     css: string;
// }

Inject the theme styles into the DOM:

import { injectTheme } from '../styled-system/themes'

const theme = await getTheme('red')
injectTheme(document.documentElement, theme) // this returns the injected style element

SSR example with NextJS:

// app/layout.tsx
import { Inter } from 'next/font/google'
import { cookies } from 'next/headers'
import { ThemeName, getTheme } from '../../styled-system/themes'

export default async function RootLayout({ children }: { children: React.ReactNode }) {
  const store = cookies()
  const themeName = store.get('theme')?.value as ThemeName
  const theme = themeName && (await getTheme(themeName))

  return (
    <html lang="en" data-panda-theme={themeName ? themeName : undefined}>
      {themeName && (
        <head>
          <style type="text/css" id={theme.id} dangerouslySetInnerHTML={{ __html: theme.css }} />
        </head>
      )}
      <body>{children}</body>
    </html>
  )
}

// app/page.tsx
import { getTheme, injectTheme } from '../../styled-system/themes'

export default function Home() {
  return (
    <>
      <button
        onClick={async () => {
          const current = document.documentElement.dataset.pandaTheme
          const next = current === 'primary' ? 'secondary' : 'primary'
          const theme = await getTheme(next)
          setCookie('theme', next, 7)
          injectTheme(document.documentElement, theme)
        }}
      >
        swap theme
      </button>
    </>
  )
}

// Set a Cookie
function setCookie(cName: string, cValue: any, expDays: number) {
  let date = new Date()
  date.setTime(date.getTime() + expDays * 24 * 60 * 60 * 1000)
  const expires = 'expires=' + date.toUTCString()
  document.cookie = cName + '=' + cValue + '; ' + expires + '; path=/'
}

Finally, you can create a theme contract to ensure that all themes have the same structure:

import { defineThemeContract } from '@pandacss/dev'

const defineTheme = defineThemeContract({
  tokens: {
    colors: {
      red: { value: '' }, // theme implementations must have a red color
    },
  },
})

defineTheme({
  selector: '.theme-secondary',
  tokens: {
    colors: {
      // ^^^^   Property 'red' is missing in type '{}' but required in type '{ red: { value: string; }; }'
      //
      // fixed with
      // red: { value: 'red' },
    },
  },
})

Cbanged

When using strictTokens: true, if you didn't have tokens (or semanticTokens) on a given Token category, you'd still not be able to use any values in properties bound to that category. Now, strictTokens will correctly only restrict properties that have values in their token category.

Example:

// panda.config.ts

export default defineConfig({
  // ...
  strictTokens: true,
  theme: {
    extend: {
      colors: {
        primary: { value: 'blue' },
      },
      // borderWidths: {}, // ⚠️ nothing defined here
    },
  },
})

// app.tsx
css({
  // ❌ before this PR, TS would throw an error as you are supposed to only use Tokens
  // even thought you don't have any `borderWidths` tokens defined !

  // ✅ after this PR, TS will not throw an error anymore as you don't have any `borderWidths` tokens
  // if you add one, this will error again (as it's supposed to)
  borderWidths: '123px',
})

Description

• Simplify typings for the style properties.
• Add the csstype comments for each property.

You will now be able to see a utility or csstype values in 2 clicks !

How

Instead of relying on TS to infer the correct type for each properties, we now just generate the appropriate value for each property based on the config.

This should make it easier to understand the type of each property and might also speed up the TS suggestions as there's less to infer.

[0.35.0] - 2024-03-14

Fixed

• Fix negative semanticTokens generation

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  tokens: {
    spacing: {
      1: { value: '1rem' },
    },
  },
  semanticTokens: {
    spacing: {
      lg: { value: '{spacing.1}' },
    },
  },
})

Will now correctly generate the negative value:

"spacing.-1" => "calc(var(--spacing-1) * -1)",
- "spacing.-lg" => "{spacing.1}",
+ "spacing.-lg" => "calc(var(--spacing-lg) * -1)",

• Fix extraction of JSX styled factory when using namespace imports

import * as pandaJsx from '../styled-system/jsx'

// ✅ this will work now
pandaJsx.styled('div', { base: { color: 'red' } })
const App = () => <pandaJsx.styled.span color="blue">Hello</pandaJsx.styled.span>

Added

• Allow using ! or !important when using strictTokens: true (without TS throwing an error)
• Add missing reducers to properly return the results of hooks for config:resolved and parser:before
• Add missing methods for ParserResultInterface (which can be used in the parser:after hook to dynamically add extraction results from your own logic, like using a custom parser)
• Add allow config option in postcss plugin.
• Add an optional className key in sva config which will can be used to target slots in the DOM.

Each slot will contain a ${className}__${slotName} class in addition to the atomic styles.

import { sva } from '../styled-system/css'

const button = sva({
  className: 'btn',
  slots: ['root', 'text'],
  base: {
    root: {
      bg: 'blue.500',
      _hover: {
        // v--- 🎯 this will target the `text` slot
        '& .btn__text': {
          color: 'white',
        },
      },
    },
  },
})

export const App = () => {
  const classes = button()
  return (
    <div className={classes.root}>
      <div className={classes.text}>Click me</div>
    </div>
  )
}

The plugin won't parse css files in node modules. This config option lets you opt out of that for some paths.

//postcss.config.cjs

module.exports = {
  plugins: {
    '@pandacss/dev/postcss': {
      allow: [/node_modules\/.embroider/],
    },
  },
}

Changed

• Change the styled-system/token JS token function to use raw value for semanticToken that do not have conditions other than base

export default defineConfig({
  semanticTokens: {
    colors: {
      blue: { value: 'blue' },
      green: {
        value: {
          base: 'green',
          _dark: 'white',
        },
      },
      red: {
        value: {
          base: 'red',
        },
      },
    },
  },
})

This is the output of the styled-system/token JS token function:

const tokens = {
    "colors.blue": {
-     "value": "var(--colors-blue)",
+     "value": "blue",
      "variable": "var(--colors-blue)"
    },
    "colors.green": {
      "value": "var(--colors-green)",
      "variable": "var(--colors-green)"
    },
    "colors.red": {
-     "value": "var(--colors-red)",
+     "value": "red",
      "variable": "var(--colors-red)"
    },
}

[0.34.3] - 2024-03-09

Fixed

Fix nested styled factory composition

import { styled } from '../styled-system/jsx'

const BasicBox = styled('div', { base: { fontSize: '10px' } })
const ExtendedBox1 = styled(BasicBox, { base: { fontSize: '20px' } })
const ExtendedBox2 = styled(ExtendedBox1, { base: { fontSize: '30px' } })

export const App = () => {
  return (
    <>
      {/* ✅ fs_10px */}
      <BasicBox>text1</BasicBox>
      {/* ✅ fs_20px */}
      <ExtendedBox1>text2</ExtendedBox1>
      {/* BEFORE: ❌ fs_10px fs_30px */}
      {/* NOW: ✅ fs_30px */}
      <ExtendedBox2>text3</ExtendedBox2>
    </>
  )
}

Added

Allow color opacity modifier when using strictTokens, e.g color: "blue.200/50" will not throw a TS error anymore

0.34.2 - 2024-03-08

Fixed

• Fix strictPropertyValues with border* properties

We had listed border\* properties as affected by strictPropertyValues but they shouldn't be restricted as their syntax is too complex to be restricted. This removes any border* properties that do not specifically end with Style like borderTopStyle.

import { css } from '../styled-system/css'

css({
  borderTop: '1px solid red', // ✅ will now be fine as it should be
  borderTopStyle: 'abc', // ✅ will still report a TS error
})

• Fix a false positive with the validation check that reported Missing token when using a color opacity modifier in config tokens or semanticTokens

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  validation: 'warn',
  conditions: {
    light: '.light &',
    dark: '.dark &',
  },
  theme: {
    tokens: {
      colors: {
        blue: { 500: { value: 'blue' } },
        green: { 500: { value: 'green' } },
      },
      opacity: {
        half: { value: 0.5 },
      },
    },
    semanticTokens: {
      colors: {
        secondary: {
          value: {
            base: 'red',
            _light: '{colors.blue.500/32}',
            _dark: '{colors.green.500/half}',
          },
        },
      },
    },
  },
})

Would incorrectly report:

• [tokens] Missing token: colors.green.500/half used in config.semanticTokens.colors.secondary
• [tokens] Missing token: colors.blue.500/32 used in config.semanticTokens.colors.secondary

Added

Allow using namespaced imports

import * as p from 'styled-system/patterns'
import * as recipes from 'styled-system/recipes'
import * as panda from 'styled-system/css'

// this will now be extracted
p.stack({ mt: '40px' })

recipes.cardStyle({ rounded: true })

panda.css({ color: 'red' })
panda.cva({ base: { color: 'blue' } })
panda.sva({ base: { root: { color: 'green' } } })

0.34.1 - 2024-03-06

Fixed

Fix the color opacity modifier syntax for semanticTokens inside of conditions

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  conditions: {
    light: '.light &',
    dark: '.dark &',
  },
  theme: {
    tokens: {
      colors: {
        blue: { 500: { value: 'blue' } },
        green: { 500: { value: 'green' } },
      },
      opacity: {
        half: { value: 0.5 },
      },
    },
    semanticTokens: {
      colors: {
        secondary: {
          value: {
            base: 'red',
            _light: '{colors.blue.500/32}', // <-- wasn't working as expected
            _dark: '{colors.green.500/half}',
          },
        },
      },
    },
  },
})

will now correctly generate the following CSS:

@layer tokens {
  :where(:root, :host) {
    --colors-blue-500: blue;
    --colors-green-500: green;
    --opacity-half: 0.5;
    --colors-secondary: red;
  }

  .light {
    --colors-secondary: color-mix(in srgb, var(--colors-blue-500) 32%, transparent);
  }

  .dark {
    --colors-secondary: color-mix(in srgb, var(--colors-green-500) 50%, transparent);
  }
}

0.34.0 - 2024-03-06

Fixed

• Fix issue where text accent color token was nested incorrectly.
• Fix splitCssProps typings, it would sometimes throw Expression produces a union type that is too complex to represent"
• Fix "missing token" warning when using DEFAULT in tokens path

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  validation: 'error',
  theme: {
    semanticTokens: {
      colors: {
        primary: {
          DEFAULT: { value: '#ff3333' },
          lighter: { value: '#ff6666' },
        },
        background: { value: '{colors.primary}' }, // <-- ⚠️ wrong warning
        background2: { value: '{colors.primary.lighter}' }, // <-- no warning, correct
      },
    },
  },
})

Added

• Add a config validation check to prevent using spaces in token keys, show better error logs when there's a CSS parsing error
• Add a warning when using value twice in config

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  validation: 'error',
  theme: {
    tokens: {
      colors: {
        primary: { value: '#ff3333' },
      },
    },
    semanticTokens: {
      colors: {
        primary: {
          value: { value: '{colors.primary}' }, // <-- ⚠️ new warning for this
        },
      },
    },
  },
})

• Allow using the color opacity modifier syntax (blue.300/70) in token references:

1. {colors.blue.300/70}
2. token(colors.blue.300/70)

Note that this works both in style usage and in build-time config.

// runtime usage

import { css } from '../styled-system/css'

css({ bg: '{colors.blue.300/70}' })
// => @layer utilities {
//    .bg_token\(colors\.blue\.300\/70\) {
//      background: color-mix(in srgb, var(--colors-blue-300) 70%, transparent);
//    }
//  }

css({ bg: 'token(colors.blue.300/70)' })
// => @layer utilities {
//    .bg_token\(colors\.blue\.300\/70\) {
//      background: color-mix(in srgb, var(--colors-blue-300) 70%, transparent);
//    }
//  }

// build-time usage
import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  theme: {
    tokens: {
      colors: {
        blue: {
          300: { value: '#00f' },
        },
      },
    },
    semanticTokens: {
      colors: {
        primary: {
          value: '{colors.blue.300/70}',
        },
      },
    },
  },
})

@layer tokens {
  :where(:root, :host) {
    --colors-blue-300: #00f;
    --colors-primary: color-mix(in srgb, var(--colors-blue-300) 70%, transparent);
  }
}

Changed

Deprecates emitPackage, it will be removed in the next major version.

Why?

It's known for causing several issues:

• bundlers sometimes eagerly cache the node_modules, leading to panda codegen updates to the styled-system not visible in the browser
• auto-imports are not suggested in your IDE.
• in some IDE the typings are not always reflected properly

As alternatives, you can use:

• relative paths instead of absolute paths (e.g. ../styled-system/css instead of styled-system/css)
• use package.json #imports and/or tsconfig path aliases (prefer package.json#imports when possible, TS 5.4 supports them by default) like #styled-system/css instead of styled-system/css
• for a component library, use a dedicated workspace package (e.g. @acme/styled-system) and use importMap: "@acme/styled-system" so that Panda knows which entrypoint to extract, e.g. import { css } from '@acme/styled-system/css'

0.33.0 - 2024-02-27

Fixed

• Fix an issue with recipes that lead to in-memory duplication the resulting CSS, which would increase the time taken to output the CSS after each extraction in the same HMR session (by a few ms).
• Fix svg token asset quotes
• Fix conditions accessing Cannot read properties of undefined (reading 'raw')

Added

• Allow dynamically recording profiling session by pressing the p key in your terminal when using the --cpu-prof flag for long-running sessions (with -w or --watch for panda / panda cssgen / panda codegen).
• Add definePlugin config functions for type-safety around plugins, add missing plugins in config dependencies to trigger a config reload on plugins change
• Add a group to every utility in the @pandacss/preset-base, this helps Panda tooling organize utilities.
• Add support for element level css reset via preflight.level. Learn more here.

Setting preflight.level to 'element' applies the reset directly to the individual elements that have the scope class assigned.

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  preflight: {
    scope: '.my-scope',
    level: 'element', // 'element' | 'parent (default)'
  },
  // ...
})

This will generate CSS that looks like:

button.my-scope {
}

img.my-scope {
}

This approach allows for more flexibility, enabling selective application of CSS resets either to an entire parent container or to specific elements within a container.

Changed

• Unify the token path syntax when using formatTokenName

Example with the following config:

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  hooks: {
    'tokens:created': ({ configure }) => {
      configure({
        formatTokenName: (path: string[]) => '$' + path.join('-'),
      })
    },
  },
})

Will now allow you to use the following syntax for token path:

- css({ boxShadow: '10px 10px 10px {colors.$primary}' })
+ css({ boxShadow: '10px 10px 10px {$colors-primary}' })

- token.var('colors.$primary')
+ token.var('$colors-black')

0.32.1 - 2024-02-23

Fixed

• Fix issue where svg asset tokens doesn't work as expected due to unbalanced quotes.

• Prevent extracting style props of styled when not explicitly imported

• Allow using multiple aliases for the same identifier for the /css entrypoints just like /patterns and /recipes

import { css } from '../styled-system/css'
import { css as css2 } from '../styled-system/css'

css({ display: 'flex' })
css2({ flexDirection: 'column' }) // this wasn't working before, now it does

Added

• Add missing config dependencies for some styled-system/types files
• Add a way to create config conditions with nested at-rules/selectors

export default defaultConfig({
  conditions: {
    extend: {
      supportHover: ['@media (hover: hover) and (pointer: fine)', '&:hover'],
    },
  },
})

import { css } from '../styled-system/css'

css({
  _supportHover: {
    color: 'red',
  },
})

will generate the following CSS:

@media (hover: hover) and (pointer: fine) {
  &:hover {
    color: red;
  }
}

Changed

Using colorPalette with DEFAULT values will now also override the current token path

Given this config:

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  theme: {
    extend: {
      semanticTokens: {
        colors: {
          bg: {
            primary: {
              DEFAULT: {
                value: '{colors.red.500}',
              },
              base: {
                value: '{colors.green.500}',
              },
              hover: {
                value: '{colors.yellow.300}',
              },
            },
          },
        },
      },
    },
  },
})

And this style usage:

import { css } from 'styled-system/css'

css({
  colorPalette: 'bg.primary',
})

This is the difference in the generated css

@layer utilities {
  .color-palette_bg\\.primary {
+    --colors-color-palette: var(--colors-bg-primary);
    --colors-color-palette-base: var(--colors-bg-primary-base);
    --colors-color-palette-hover: var(--colors-bg-primary-hover);
  }
}

Which means you can now directly reference the current colorPalette like:

import { css } from 'styled-system/css'

css({
  colorPalette: 'bg.primary',
+  backgroundColor: 'colorPalette',
})

0.32.0 - 2024-02-19

Fixed

• Fix issue in defineParts where it silently fails if a part not defined is used. It now errors with a helpful message
• Automatically generate a recipe compoundVariants when using staticCss
• Fix issue where 0 values doesn't get extracted when used in a condition

Changed

• Always sort all to be first, so that other properties can easily override it
• Switch from em to rem for breakpoints and container queries to prevent side effects.
• Allow config.hooks to be shared in plugins

For hooks that can transform Panda's internal state by returning something (like cssgen:done and codegen:prepare), each hook instance will be called sequentially and the return result (if any) of the previous hook call is passed to the next hook so that they can be chained together.

• Allow the user to set jsxFramework to any string to enable extracting JSX components.

Context: In a previous version, Panda's extractor used to always extract JSX style props even when not specifying a jsxFramework. This was considered a bug and has been fixed, which reduced the amount of work panda does and artifacts generated if the user doesn't need jsx.

Now, in some cases like when using Svelte or Astro, the user might still to use & extract JSX style props, but the jsxFramework didn't have a way to specify that. This change allows the user to set jsxFramework to any string to enable extracting JSX components without generating any artifacts.

0.31.0 - 2024-02-13

Fixed

• Fix styled factory nested composition with cva
• Fix issue in token validation logic where token with additional properties like description is considered invalid.
• When validation is set to error, show all config errors at once instead of stopping at the first error.

Added

• Add a RecipeVariant type to get the variants in a strict object from cva function. This complements the RecipeVariantprops type that extracts the variant as optional props, mostly intended for JSX components.
• Add missing log with the panda -w CLI, expose resolveConfig from @pandacss/config
• Add a config.polyfill option that will polyfill the CSS @layer at-rules using a postcss plugin
• And --polyfill flag to panda and panda cssgen commands
• Add textShadowColor utility

css({
  textShadow: '1px 1px 1px var(--text-shadow-color)',
  textShadowColor: 'black',
})

Changed

• Automatically merge the base object in the css root styles in the runtime
• Sort the longhand/shorthand atomic rules in a deterministic order to prevent property conflicts

This may be a breaking change depending on how your styles are created

Ex:

css({
  padding: '1px',
  paddingTop: '3px',
  paddingBottom: '4px',
})

Will now always generate the following css:

@layer utilities {
  .p_1px {
    padding: 1px;
  }

  .pt_3px {
    padding-top: 3px;
  }

  .pb_4px {
    padding-bottom: 4px;
  }
}

0.30.02 - 2024-02-08

Fixed

• Fix issue where v-model does not work in vue styled factory
• Fix issue where styled factory in Solid.js could results in Maximum call stack exceeded when composing with another library that uses the as prop.
• Fix issue where the param for --outdir was missing, leading to errors

Added

Allow configuring the matchTag / matchTagProp functions to customize the way Panda extracts your JSX. This can be especially useful when working with libraries that have properties that look like CSS properties but are not and should be ignored.

Note: This feature mostly affects users who have jsxStyleProps set to all. This is currently the default.

Setting it to minimal (which also allows passing the css prop) or none (which disables the extraction of CSS properties) will make this feature less useful.

Here's an example with Radix UI where the Select.Content component has a position property that should be ignored:

// Here, the `position` property will be extracted because `position` is a valid CSS property
<Select.Content position="popper" sideOffset={5}>

export default defineConfig({
  // ...
  hooks: {
    'parser:before': ({ configure }) => {
      configure({
        // ignore the Select.Content entirely
        matchTag: (tag) => tag !== 'Select.Content',
        // ...or specifically ignore the `position` property
        matchTagProp: (tag, prop) => tag === 'Select.Content' && prop !== 'position',
      })
    },
  },
})

0.30.01 - 2024-02-05

Fixed

Fix the regression caused by the downstream bundle-n-require package, which tries to load custom conditions first. This led to a could not resolve @pandacss/dev error

0.30.0 - 2024-02-05

Fixed

• Fix issue where config changes could not be detected due to config bundling returning stale result sometimes.
• Fix issue where errors were thrown when semantic tokens are overriden in tokens.
• Fix issue where responsive array in css and cva doesn't generate the correct classname

Added

• Add utils functions in the config:resolved hook, making it easy to apply transformations after all presets have been merged.

For example, this could be used if you want to use most of a preset but want to completely omit a few things, while keeping the rest. Let's say we want to remove the stack pattern from the built-in @pandacss/preset-base:

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  hooks: {
    'config:resolved': ({ config, utils }) => {
      return utils.omit(config, ['patterns.stack'])
    },
  },
})

• Add a --logfile flag to the panda, panda codegen, panda cssgen and panda debug commands.
• Add a logfile option to the postcss plugin

Logs will be streamed to the file specified by the --logfile flag or the logfile option. This is useful for debugging issues that occur during the build process.

panda --logfile ./logs/panda.log

module.exports = {
  plugins: {
    '@pandacss/dev/postcss': {
      logfile: './logs/panda.log',
    },
  },
}

• Introduce 3 new hooks:

tokens:created

This hook is called when the token engine has been created. You can use this hook to add your format token names and variables.

This is especially useful when migrating from other css-in-js libraries, like Stitches.

export default defineConfig({
  // ...
  hooks: {
    'tokens:created': ({ configure }) => {
      configure({
        formatTokenName: (path) => '$' + path.join('-'),
      })
    },
  },
})

utility:created

This hook is called when the internal classname engine has been created. You can override the default toHash function used when config.hash is set to true

export default defineConfig({
  // ...
  hooks: {
    'utility:created': ({ configure }) => {
      configure({
        toHash: (paths, toHash) => {
          const stringConds = paths.join(':')
          const splitConds = stringConds.split('_')
          const hashConds = splitConds.map(toHash)
          return hashConds.join('_')
        },
      })
    },
  },
})

codegen:prepare

This hook is called right before writing the codegen files to disk. You can use this hook to tweak the codegen files

export default defineConfig({
  // ...
  hooks: {
    'codegen:prepare': ({ artifacts, changed }) => {
      // do something with the emitted js/d.ts files
    },
  },
})

Changed

• Refactor the --cpu-prof profiler to use the node:inspector instead of relying on an external module (v8-profiler-next, which required node-gyp)

0.29.1 - 2024-01-30

Fixed

Fix an issue (introduced in v0.29) with panda init and add an assert on the new colorMix utility function

0.29.0 - 2024-01-29

Fixed

• Fix an issue where the curly token references would not be escaped if the token path was not found.

Added

Add config validation

• Check for duplicate between token & semanticTokens names
• Check for duplicate between recipes/patterns/slots names
• Check for token / semanticTokens paths (must end/contain 'value')
• Check for self/circular token references
• Check for missing tokens references
• Check for conditions selectors (must contain '&')
• Check for breakpoints units (must be the same)

You can set validate: 'warn' in your config to only warn about errors or set it to none to disable validation entirely.

Default values in patterns

You can now set and override defaultValues in pattern configurations.

Here's an example of how to define a new hstack pattern with a default gap value of 40px:

defineConfig({
  patterns: {
    hstack: {
      properties: {
        justify: { type: 'property', value: 'justifyContent' },
        gap: { type: 'property', value: 'gap' },
      },
      // you can also use a token like '10'
      defaultValues: { gap: '40px' },
      transform(props) {
        const { justify, gap, ...rest } = props
        return {
          display: 'flex',
          alignItems: 'center',
          justifyContent: justify,
          gap,
          ...rest,
        }
      },
    },
  },
})

Media query curly braces tokens

Add support for token references with curly braces like {path.to.token} in media queries, just like the token(path.to.token) alternative already could.

css({
  // ✅ this is fine now, will resolve to something like
  // `@container (min-width: 56em)`
  '@container (min-width: {sizes.4xl})': {
    color: 'green',
  },
})

Color opacifier

Update every utilities connected to the colors tokens in the @pandacss/preset-base (included by default) to use the color-mix CSS function.

This function allows you to mix two colors together, and we use it to change the opacity of a color using the {color}/{opacity} syntax.

You can use it like this:

css({
  bg: 'red.300/40',
  color: 'white',
})

This will generate:

@layer utilities {
  .bg_red\.300\/40 {
    --mix-background: color-mix(in srgb, var(--colors-red-300) 40%, transparent);
    background: var(--mix-background, var(--colors-red-300));
  }

  .text_white {
    color: var(--colors-white);
  }
}

• If you're not using any opacity, the utility will not use color-mix
• The utility will automatically fallback to the original color if the color-mix function is not supported by the browser.
• You can use any of the color tokens, and any of the opacity tokens.

---

The utilities transform function also receives a new utils object that contains the colorMix function, so you can also use it on your own utilities:

export default defineConfig({
  utilities: {
    background: {
      shorthand: 'bg',
      className: 'bg',
      values: 'colors',
      transform(value, args) {
        const mix = args.utils.colorMix(value)
        // This can happen if the value format is invalid (e.g. `bg: red.300/invalid` or `bg: red.300//10`)
        if (mix.invalid) return { background: value }

        return {
          background: mix.value,
        }
      },
    },
  },
})

---

Here's a cool snippet (that we use internally !) that makes it easier to create a utility transform for a given property:

import type { PropertyTransform } from '@pandacss/types'

export const createColorMixTransform =
  (prop: string): PropertyTransform =>
  (value, args) => {
    const mix = args.utils.colorMix(value)
    if (mix.invalid) return { [prop]: value }

    const cssVar = '--mix-' + prop

    return {
      [cssVar]: mix.value,
      [prop]: `var(${cssVar}, ${mix.color})`,
    }
  }

then the same utility transform as above can be written like this:

export default defineConfig({
  utilities: {
    background: {
      shorthand: 'bg',
      className: 'bg',
      values: 'colors',
      transform: createColorMixTransform('background'),
    },
  },
})

Container queries Theme

Improve support for CSS container queries by adding a new containerNames and containerSizes theme options.

You can new define container names and sizes in your theme configuration and use them in your styles.

export default defineConfig({
  // ...
  theme: {
    extend: {
      containerNames: ['sidebar', 'content'],
      containerSizes: {
        xs: '40em',
        sm: '60em',
        md: '80em',
      },
    },
  },
})

The default container sizes in the @pandacss/preset-panda preset are shown below:

export const containerSizes = {
  xs: '320px',
  sm: '384px',
  md: '448px',
  lg: '512px',
  xl: '576px',
  '2xl': '672px',
  '3xl': '768px',
  '4xl': '896px',
  '5xl': '1024px',
  '6xl': '1152px',
  '7xl': '1280px',
  '8xl': '1440px',
}

Then use them in your styles by referencing using @<container-name>/<container-size> syntax:

The default container syntax is @/<container-size>.

import { css } from '/styled-system/css'

function Demo() {
  return (
    <nav className={css({ containerType: 'inline-size' })}>
      <div
        className={css({
          fontSize: { '@/sm': 'md' },
        })}
      />
    </nav>
  )
}

This will generate the following CSS:

.cq-type_inline-size {
  container-type: inline-size;
}

@container (min-width: 60em) {
  .\@\/sm:fs_md {
    container-type: inline-size;
  }
}

Container Query Pattern

To make it easier to use container queries, we've added a new cq pattern to @pandacss/preset-base.

import { cq } from 'styled-system/patterns'

function Demo() {
  return (
    <nav className={cq()}>
      <div
        className={css({
          fontSize: { base: 'lg', '@/sm': 'md' },
        })}
      />
    </nav>
  )
}

You can also named container queries:

import { cq } from 'styled-system/patterns'

function Demo() {
  return (
    <nav className={cq({ name: 'sidebar' })}>
      <div
        className={css({
          fontSize: { base: 'lg', '@sidebar/sm': 'md' },
        })}
      />
    </nav>
  )
}

Config

• Add support for explicitly specifying config related files that should trigger a context reload on change.

  We automatically track the config file and (transitive) files imported by the config file as much as possible, but sometimes we might miss some. You can use this option as a workaround for those edge cases.

  Set the dependencies option in panda.config.ts to a glob or list of files.

  export default defineConfig({
    // ...
    dependencies: ['path/to/files/**.ts'],
  })
  

• Invoke config:change hook in more situations (when the --watch flag is passed to panda codegen, panda cssgen, panda ship)

• Watch for more config options paths changes, so that the related artifacts will be regenerated a bit more reliably (ex: updating the config.hooks will now trigger a full regeneration of styled-system)

Changed

• Set display: none for hidden elements in reset css
• Updated the default preset in Panda to use the new defaultValues feature.

To override the default values, consider using the extend pattern.

defineConfig({
  patterns: {
    extend: {
      stack: {
        defaultValues: { gap: '20px' },
      },
    },
  },
})

0.28.0 - 2024-01-24

Fixed

• Allow custom logo in studio
• Update getArbitraryValue so it works for values that start on a new line
• Fix issue where /* @__PURE__ */ annotation threw a warning in Vite build due to incorrect placement.
• Fix a typing issue where the borderWidths wasn't specified in the generated TokenCategory type
• Fix issue where throws "React is not defined error"
• Fix a regression with rule insertion order after triggering HMR that re-uses some CSS already generated in previous triggers, introuced in v0.27.0
• Fix the issue in the utility configuration where shorthand without className returns incorrect CSS when using the shorthand version.

utilities: {
  extend: {
    coloredBorder: {
      shorthand: 'cb', // no classname, returns incorrect css
      values: ['red', 'green', 'blue'],
      transform(value) {
        return {
          border: `1px solid ${value}`,
        };
      },
    },
  },
},

• Fix a regression with globalCss selector order

{
    globalCss: {
        html: {
          ".aaa": {
            color: "red.100",
            "& .bbb": {
              color: "red.200",
              "& .ccc": {
                color: "red.300"
              }
            }
          }
        },
    }
}

would incorrectly generate (regression introduced in v0.26.2)

.aaa html {
  color: var(--colors-red-100);
}

.aaa html .bbb {
  color: var(--colors-red-200);
}

.aaa html .bbb .ccc {
  color: var(--colors-red-300);
}

will now correctly generate again:

html .aaa {
  color: var(--colors-red-100);
}

html .aaa .bbb {
  color: var(--colors-red-200);
}

html .aaa .bbb .ccc {
  color: var(--colors-red-300);
}

Added

• Add a --cpu-prof flag to panda, panda cssgen, panda codegen and panda debug commands This is useful for debugging performance issues in panda itself. This will generate a panda-{command}-{timestamp}.cpuprofile file in the current working directory, which can be opened in tools like Speedscope
• Slight perf improvement by caching a few computed properties that contains a loop

This is mostly intended for maintainers or can be asked by maintainers to help debug issues.

Changed

Refactor config.hooks to be much more powerful, you can now:

• Tweak the config after it has been resolved (after presets are loaded and merged), this could be used to dynamically load all recipes from a folder
• Transform a source file's content before parsing it, this could be used to transform the file content to a tsx-friendly syntax so that Panda's parser can parse it.
• Implement your own parser logic and add the extracted results to the classic Panda pipeline, this could be used to parse style usage from any template language
• Tweak the CSS content for any @layer or even right before it's written to disk (if using the CLI) or injected through the postcss plugin, allowing all kinds of customizations like removing the unused CSS variables, etc.
• React to any config change or after the codegen step (your outdir, the styled-system folder) have been generated

See the list of available config.hooks here:

export interface PandaHooks {
  /**
   * Called when the config is resolved, after all the presets are loaded and merged.
   * This is the first hook called, you can use it to tweak the config before the context is created.
   */
  'config:resolved': (args: { conf: LoadConfigResult }) => MaybeAsyncReturn
  /**
   * Called when the Panda context has been created and the API is ready to be used.
   */
  'context:created': (args: { ctx: ApiInterface; logger: LoggerInterface }) => void
  /**
   * Called when the config file or one of its dependencies (imports) has changed.
   */
  'config:change': (args: { config: UserConfig }) => MaybeAsyncReturn
  /**
   * Called after reading the file content but before parsing it.
   * You can use this hook to transform the file content to a tsx-friendly syntax so that Panda's parser can parse it.
   * You can also use this hook to parse the file's content on your side using a custom parser, in this case you don't have to return anything.
   */
  'parser:before': (args: { filePath: string; content: string }) => string | void
  /**
   * Called after the file styles are extracted and processed into the resulting ParserResult object.
   * You can also use this hook to add your own extraction results from your custom parser to the ParserResult object.
   */
  'parser:after': (args: { filePath: string; result: ParserResultInterface | undefined }) => void
  /**
   * Called after the codegen is completed
   */
  'codegen:done': () => MaybeAsyncReturn
  /**
   * Called right before adding the design-system CSS (global, static, preflight, tokens, keyframes) to the final CSS
   * Called right before writing/injecting the final CSS (styles.css) that contains the design-system CSS and the parser CSS
   * You can use it to tweak the CSS content before it's written to disk or injected through the postcss plugin.
   */
  'cssgen:done': (args: {
    artifact: 'global' | 'static' | 'reset' | 'tokens' | 'keyframes' | 'styles.css'
    content: string
  }) => string | void
}

0.27.3 - 2024-01-18

Fixed

• Fix issue where HMR doesn't work when tsconfig paths is used.
• Fix prettier parser warning in panda config setup.

0.27.2 - 2024-01-17

Fixed

Switch back to node:path from pathe to resolve issues with windows path in PostCSS + Webpack set up

0.27.1 - 2024-01-15

Fixed

Fix issue in windows environments where HMR doesn't work in webpack projects.

0.27.0 - 2024-01-14

Added

• Introduce a new config.lightningcss option to use lightningcss (currently disabled by default) instead of postcss.
• Add a new config.browserslist option to configure the browserslist used by lightningcss.
• Add a --lightningcss flag to the panda and panda cssgen command to use lightningcss instead of postcss for this run.
• Add support for aspect ratio tokens in the panda config or preset. Aspect ratio tokens are used to define the aspect ratio of an element.

export default defineConfig({
  // ...
  theme: {
    extend: {
      // add aspect ratio tokens
      tokens: {
        aspectRatios: {
          '1:1': '1',
          '16:9': '16/9',
        },
      },
    },
  },
})

Here's what the default aspect ratio tokens in the base preset looks like:

{
  "square": { "value": "1 / 1" },
  "landscape": { "value": "4 / 3" },
  "portrait": { "value": "3 / 4" },
  "wide": { "value": "16 / 9" },
  "ultrawide": { "value": "18 / 5" },
  "golden": { "value": "1.618 / 1" }
}

Breaking Change

The built-in token values has been removed from the aspectRatio utility to the @pandacss/preset-base as a token.

For most users, this change should be a drop-in replacement. However, if you used a custom preset in the config, you might need to update it to include the new aspect ratio tokens.

Changed

• Enhance splitCssProps typings
• Improve the performance of the runtime transform functions by caching their results (css, cva, sva, recipe/slot recipe, patterns)

See detailed breakdown of the performance improvements here based on the React Profiler.

• Change the config dependencies (files that are transitively imported) detection a bit more permissive to make it work by default in more scenarios.

Context

This helps when you're in a monorepo and you have a workspace package for your preset, and you want to see the HMR reflecting changes in your app.

Currently, we only traverse files with the .ts extension, this change makes it traverse all files ending with .ts, meaning that it will also traverse .d.ts, .d.mts, .mts, etc.

Example

// apps/storybook/panda.config.ts
import { defineConfig } from '@pandacss/dev'
import preset from '@acme/preset'

export default defineConfig({
  // ...
})

This would not work before, but now it does.

{
  "name": "@acme/preset",
  "types": "./dist/index.d.mts", // we only looked into `.ts` files, so we didnt check this
  "main": "./dist/index.js",
  "module": "./dist/index.mjs",
}

Notes This would have been fine before that change.

// packages/preset/package.json
{
  "name": "@acme/preset",
  "types": "./src/index.ts", // this was fine
  "main": "./dist/index.js",
  "exports": {
    ".": {
      "types": "./dist/index.d.ts",
      "import": "./dist/index.mjs",
      "require": "./dist/index.js",
    },
    // ...
  },
}

0.26.2 - 2024-01-10

Fixed

Fix placeholder condition in preset-base

0.26.1 - 2024-01-09

Fixed

Hotfix strictTokens after introducing strictPropertyValues

0.26.0 - 2024-01-09

Fixed

• Fix issue where [] escape hatch clashed with named grid lines
• Fix @pandacss/postcss plugin regression when the entry CSS file (with @layer rules order) contains user-defined rules, those user-defined rules would not be reloaded correctly after being changed.
• Fix an edge-case for when the config.outdir would not be set in the panda.config

Internal details: The outdir would not have any value after a config change due to the fallback being set in the initial config resolving code path but not in context reloading code path, moving it inside the config loading function fixes this issue.

Added

• Add data-placeholder and data-placeholder-shown to preset-base conditions
• Display better CssSyntaxError logs
• Add borderWidths token to types

Changed

• Remove eject type from presets
• Refactors the parser and import analysis logic. The goal is to ensure we can re-use the import logic in ESLint Plugin and Node.js.
• config.strictTokens will only affect properties that have config tokens, such as color, bg, borderColor, etc.
• config.strictPropertyValues is added and will throw for properties that do not have config tokens, such as display, content, willChange, etc. when the value is not a predefined CSS value.

In version 0.19.0 we changed config.strictTokens typings a bit so that the only property values allowed were the config tokens OR the predefined CSS values, ex: flex for the property display, which prevented typos such as display: 'aaa'.

The problem with this change is that it means you would have to provide every CSS properties a given set of values so that TS wouldn't throw any error. Thus, we will partly revert this change and make it so that config.strictTokens shouldn't affect properties that do not have config tokens, such as content, willChange, display, etc.

v0.19.0:

// config.strictTokens = true
css({ display: 'flex' }) // OK, didn't throw
css({ display: 'block' }) // OK, didn't throw
css({ display: 'abc' }) // ❌ would throw since 'abc' is not part of predefined values of 'display' even thought there is no config token for 'abc'

now:

// config.strictTokens = true
css({ display: 'flex' }) // OK, didn't throw
css({ display: 'block' }) // OK, didn't throw
css({ display: 'abc' }) // ✅ will not throw there is no config token for 'abc'

Instead, if you want the v.19.0 behavior, you can use the new config.strictPropertyValues option. You can combine it with config.strictTokens if you want to be strict on both properties with config tokens and properties without config tokens.

The new config.strictPropertyValues option will only be applied to this exhaustive list of properties:

type StrictableProps =
  | 'alignContent'
  | 'alignItems'
  | 'alignSelf'
  | 'all'
  | 'animationComposition'

0.25.0 - 2024-01-06

Fixed

• Fix config dependencies detection by re-introducing the file tracing utility
• Fix issue where base doesn't work within css function

css({
  // This didn't work, but now it does
  base: { color: 'blue' },
})

Added

• Add a way to generate the staticCss for all recipes (and all variants of each recipe)

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  staticCss: {
    recipes: '*', // ✅ will generate the staticCss for all recipes
  },
})

• Support token reference syntax when authoring styles object, text styles and layer styles.

import { css } from '../styled-system/css'

const styles = css({
  border: '2px solid {colors.primary}',
})

This will resolve the token reference and convert it to css variables.

.border_2px_solid_\{colors\.primary\} {
  border: 2px solid var(--colors-primary);
}

The alternative to this was to use the token(...) css function which will be resolved.

token(...) vs {...}

Both approaches return the css variable

const styles = css({
  // token reference syntax
  border: '2px solid {colors.primary}',
  // token function syntax
  border: '2px solid token(colors.primary)',
})

However, The token(...) syntax allows you to set a fallback value.

const styles = css({
  border: '2px solid token(colors.primary, red)',
})

0.24.2 - 2024-01-04

Fixed

• Fix a regression with utility where boolean values would be treated as a string, resulting in "false" being seen as a truthy value
• Fix an issue with the panda init command which didn't update existing .gitignore to include the styled-system
• Fix issue where config slot recipes with compound variants were not processed correctly

0.24.1 - 2024-01-02

Fixed

• Fix an issue with the @pandacss/postcss (and therefore @pandacss/astro) where the initial @layer CSS wasn't applied correctly
• Fix an issue with staticCss where it was only generated when it was included in the config (we can generate it through the config recipes)

0.24.0 - 2024-01-02

Fixed

• Fix regression in previous implementation that increased memory usage per extraction, leading to slower performance over time

Added

Add patterns to config.staticCss

Changed

• Boost style extraction performance by moving more work away from postcss
• Using a hashing strategy, the compiler only computes styles/classname once per style object and prop-value-condition pair
• Fix the special [*] rule which used to generate the same rule for every breakpoints, which is not what most people need (it's still possible by explicitly using responsive: true).

const card = defineRecipe({
  className: 'card',
  base: { color: 'white' },
  variants: {
    size: {
      small: { fontSize: '14px' },
      large: { fontSize: '18px' },
    },
    visual: {
      primary: { backgroundColor: 'blue' },
      secondary: { backgroundColor: 'gray' },
    },
  },
})

export default defineConfig({
  // ...
  staticCss: {
    recipes: {
      card: ['*'], // this

      // was equivalent to:
      card: [
        // notice how `responsive: true` was implicitly added
        { size: ['*'], responsive: true },
        { visual: ['*'], responsive: true },
      ],

      //   will now correctly be equivalent to:
      card: [{ size: ['*'] }, { visual: ['*'] }],
    },
  },
})

Here's the diff in the generated CSS:

0.23.0 - 2023-12-15

Fixed

• Fix issue where style props wouldn't be properly passed when using config.jsxStyleProps set to minimal or none with JSX patterns (Box, Stack, Flex, etc.)
• Fix an issue with config change detection when using a custom config.slotRecipes[xxx].jsx array
• Fix performance issue where process could get slower due to postcss rules held in memory.
• Fix an issue with the postcss plugin when a config change sometimes didn't trigger files extraction
• Fix & perf improvement: skip JSX parsing when not using config.jsxFramework / skip tagged template literal parsing when not using config.syntax set to "template-literal"
• Fix a parser issue where we didn't handle import aliases when using a {xxx}.raw() function.

ex:

// button.stories.ts
import { button as buttonRecipe } from '@ui/styled-system/recipes'

export const Primary: Story = {
  // ❌ this wouldn't be parsed as a recipe because of the alias + .raw()
  //  -> ✅ it's now fixed
  args: buttonRecipe.raw({
    color: 'primary',
  }),
}

Added

• Add support for emit-pkg command to emit just the package.json file with the required entrypoints. If an existing package.json file is present, the exports field will be updated.

When setting up Panda in a monorepo, this command is useful in monorepo setups where you want the codegen to run only in a dedicated workspace package.

• Automatically extract/generate CSS for sva even if slots are not statically extractable, since it will only produce atomic styles, we don't care much about slots for sva specifically

Currently the CSS won't be generated if the slots are missing which can be problematic when getting them from another file, such as when using Ark-UI like import { comboboxAnatomy } from '@ark-ui/anatomy'

import { sva } from '../styled-system/css'
import { slots } from './slots'

const card = sva({
  slots, // ❌ did NOT work -> ✅ will now work as expected
  base: {
    root: {
      p: '6',
      m: '4',
      w: 'md',
      boxShadow: 'md',
      borderRadius: 'md',
      _dark: { bg: '#262626', color: 'white' },
    },
    content: {
      textStyle: 'lg',
    },
    title: {
      textStyle: 'xl',
      fontWeight: 'semibold',
      pb: '2',
    },
  },
})

Changed

• Log stacktrace on error instead of only logging the message

[0.22.1] - 2023-12-15

Fixed

• Fix slotRecipes typings, the recently added recipe.staticCss added to config.recipes weren't added to config.slotRecipes
• Fix a typing issue with config.strictTokens when using the [xxx] escape-hatch syntax with property-based conditionals

css({
  bg: '[#3B00B9]', // ✅ was okay
  _dark: {
    // ✅ was okay
    color: '[#3B00B9]',
  },

  // ❌ Not okay, will be fixed in this patch
  color: {
    _dark: '[#3B00B9]',
  },
})

• Fix a regression with the @pandacss/astro integration where the automatically provided base.css would be ignored by the @pandacss/postcss plugin

• Fix a CSS generation issue with config.strictTokens when using the [xxx] escape-hatch syntax with ! or !important

css({
  borderWidth: '[2px!]',
  width: '[2px !important]',
})

0.22.0 - 2023-12-14

Fixed

• Fix issue where static-css types was not exported.
• Fix conditional variables in border radii
• Fix regression where styled-system/jsx/index had the wrong exports
• Fix potential cross-platform issues with path resolving by using pathe instead of path
• Fix issue where children does not work in styled factory's defaultProps in React, Preact and Qwik
• Fixes a missing bracket in _indeterminate condition
• Fix issue where array syntax did not generate reponsive values in mapped pattern properties

Changed

• Update csstype to support newer css features

• Redesign astro integration and studio to use the new Astro v4 (experimental) JavaScript API

• Update Astro version to v4 for the @pandacss/studio

• Improve initial css extraction time by at least 5x 🚀

  Initial extraction time can get slow when using static CSS with lots of recipes or parsing a lot of files.

  Scenarios

  • Park UI went from 3500ms to 580ms (6x faster)
  • Panda Website went from 2900ms to 208ms (14x faster)

  Potential Breaking Change

  If you use hooks in your panda.config file to listen for when css is extracted, we no longer return the css string for performance reasons. We might reconsider this in the future.

0.21.0 - 2023-12-09

Fixed

• Fix static extraction issue when using JSX attributes (props) that are other JSX nodes

While parsing over the AST Nodes, due to an optimization where we skipped retrieving the current JSX element and instead kept track of the latest one, the logic was flawed and did not extract other properties after encountering a JSX attribute that was another JSX node.

const Component = () => {
  return (
    <>
      {/* ❌ this wasn't extracting ml="2" */}
      <Flex icon={<svg className="icon" />} ml="2" />

      {/* ✅ this was fine */}
      <Stack ml="4" icon={<div className="icon" />} />
    </>
  )
}

Now both will be fine again.

• Fix an edge-case when Panda eagerly extracted and tried to generate the CSS for a JSX property that contains an URL.

const App = () => {
  // here the content property is a valid CSS property, so Panda will try to generate the CSS for it
  // but since it's an URL, it would produce invalid CSS
  // we now check if the property value is an URL and skip it if needed
  return <CopyButton content="https://www.buymeacoffee.com/grizzlycodes" />
}

• Fix an issue where recipe variants that clash with utility shorthand don't get generated due to the normalization that happens internally.
• Fix issue where Preact JSX types are not merging recipes correctly
• Fix vue styled factory internal class merging, for example:

<script setup>
import { styled } from '../styled-system/jsx'

const StyledButton = styled('button', {
  base: {
    bgColor: 'red.300',
  },
})
</script>
<template>
  <StyledButton id="test" class="test">
    <slot></slot>
  </StyledButton>
</template>

Will now correctly include the test class in the final output.

Added

• Add configPath and cwd options in the @pandacss/astro integration just like in the @pandacss/postcss

This can be useful with Nx monorepos where the panda.config.ts is not in the root of the project.

• Add an escape-hatch for arbitrary values when using config.strictTokens, by prefixing the value with [ and suffixing with ], e.g. writing [123px] as a value will bypass the token validation.

import { css } from '../styled-system/css'

css({
  // @ts-expect-error TS will throw when using from strictTokens: true
  color: '#fff',
  // @ts-expect-error TS will throw when using from strictTokens: true
  width: '100px',

  // ✅ but this is now allowed:
  bgColor: '[rgb(51 155 240)]',
  fontSize: '[12px]',
})

• Add a shortcut for the config.importMap option

You can now also use a string to customize the base import path and keep the default entrypoints:

{
  "importMap": "@scope/styled-system"
}

is the equivalent of:

{
  "importMap": {
    "css": "@scope/styled-system/css",
    "recipes": "@scope/styled-system/recipes",
    "patterns": "@scope/styled-system/patterns",
    "jsx": "@scope/styled-system/jsx"
  }
}

• Add a way to specify a recipe's staticCss options from inside a recipe config, e.g.:

import { defineRecipe } from '@pandacss/dev'

const card = defineRecipe({
  className: 'card',
  base: { color: 'white' },
  variants: {
    size: {
      small: { fontSize: '14px' },
      large: { fontSize: '18px' },
    },
  },
  staticCss: [{ size: ['*'] }],
})

would be the equivalent of defining it inside the main config:

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  // ...
  staticCss: {
    recipes: {
      card: {
        size: ['*'],
      },
    },
  },
})

• Add Open Props preset

0.20.1 - 2023-12-01

Fixed

• Fix issue where conditional recipe variant doesn't work as expected
• Fix issue with the token(xxx.yyy) fn used in AtRule, things like:

css({
  '@container (min-width: token(sizes.xl))': {
    color: 'green.300',
  },
  '@media (min-width: token(sizes.2xl))': {
    color: 'red.300',
  },
})

Added

• Add a --watch flag to the panda ship command
• Add support for granular config change detection
• Improve the codegen experience by only rewriting files affecteds by a config change
• Added strokeWidth to svg utilities.
• Connected outlineWidth utility to borderWidths token.
• Add borderWidth, borderTopWidth, borderLeftWidth, borderRightWidth, borderBottomWidth to berder utilities.
• Add support for staticCss in presets allowing you create sharable, pre-generated styles
• Add support for extending staticCss defined in presets

const presetWithStaticCss = definePreset({
  staticCss: {
    recipes: {
      // generate all button styles and variants
      button: ['*'],
    },
  },
})

export default defineConfig({
  presets: [presetWithStaticCss],
  staticCss: {
    extend: {
      recipes: {
        // extend and pre-generate all sizes for card
        card: [{ size: ['small', 'medium', 'large'] }],
      },
    },
  },
})

0.19.0 - 2023-11-24

Fixed

• Fix issue where typescript error is shown in recipes when exactOptionalPropertyTypes is set.

  To learn more about this issue, see this issue

• Fix issue in preflight where monospace fallback pointed to the wrong variable
• Fix issue where css variables were not supported in layer styles and text styles types.
• Fix issue where recipe artifacts might not match the recipes defined in the theme due to the internal cache not being cleared as needed.

Changed

• Require explicit installation of @pandacss/studio to use the panda studio command.
• Improves the config.strictTokens type-safety by allowing CSS predefined values (like 'flex' or 'block' for the property 'display') and throwing when using anything else than those, if no theme tokens was found on that property.

Before:

// config.strictTokens = true
css({ display: 'flex' }) // OK, didn't throw
css({ display: 'block' }) // OK, didn't throw
css({ display: 'abc' }) // ❌ didn't throw even though 'abc' is not a valid value for 'display'

Now:

// config.strictTokens = true
css({ display: 'flex' }) // OK, didn't throw
css({ display: 'block' }) // OK, didn't throw
css({ display: 'abc' }) // ✅ will throw since 'abc' is not a valid value for 'display'

0.18.3 - 2023-11-15

Fixed

• Fix issue with forceConsistentTypeExtension where the composition.d.mts had an incorrect type import
• Fix issue in studio here userland @ark-ui/react version could interfere with studio version

0.18.2 - 2023-11-10

Fixed

• Fix regression in grid pattern where columns doesn't not work as expected.

0.18.1 - 2023-11-09

Fixed

• Fix issue where virtual color does not apply DEFAULT color in palette
• Fix issue where composite tokens (shadows, border, etc) generated incorrect css when using the object syntax in semantic tokens.
• Fix issue where hideBelow breakpoints are inclusive of the specified breakpoints
• Fix an issue with the grid pattern from @pandacss/preset-base (included by default), setting a minChildWidth wasn't interpreted as a token value

Before:

<div className={grid({ minChildWidth: '80px', gap: 8 })} />
// ✅ grid-template-columns: repeat(auto-fit, minmax(80px, 1fr))

<div className={grid({ minChildWidth: '20', gap: 8 })} />
// ❌ grid-template-columns: repeat(auto-fit, minmax(20, 1fr))
//                                                  ^^^

After:

<div className={grid({ minChildWidth: '80px', gap: 8 })} />
// ✅ grid-template-columns: repeat(auto-fit, minmax(80px, 1fr))

<div className={grid({ minChildWidth: '20', gap: 8 })} />
// ✅ grid-template-columns: repeat(auto-fit, minmax(var(--sizes-20, 20), 1fr))
//                                                  ^^^^^^^^^^^^^^^^^^^

css({ hideBelow: 'lg' })
// => @media screen and (max-width: 63.9975em) { background: red; }

Added

• Support arbitrary breakpoints in hideBelow and hideFrom utilities

css({ hideFrom: '800px' })
// => @media screen and (min-width: 800px) { background: red; }

Changed

• Make _requiredcondition target [data-required] and [aria-required=true] attributes

0.18.0 - 2023-11-06

Fixed

• Fix issue in template literal mode where comma-separated selectors don't work when multiline
• Fix CLI interactive mode syntax question values and prettify the generated panda.config.ts file
• Improve semantic colors in studio

Added

• Add a --only-config flag for the panda debug command, to skip writing app files and just output the resolved config.
• Add --strict-tokens flag and question in the interactive CLI
• Add a splitCssProps utility exported from the {outdir}/jsx entrypoint

import { splitCssProps, styled } from '../styled-system/jsx'
import type { HTMLStyledProps } from '../styled-system/types'

function SplitComponent({ children, ...props }: HTMLStyledProps<'div'>) {
  const [cssProps, restProps] = splitCssProps(props)
  return (
    <styled.div {...restProps} className={css({ display: 'flex', height: '20', width: '20' }, cssProps)}>
      {children}
    </styled.div>
  )
}

// Usage

function App() {
  return <SplitComponent margin="2">Click me</SplitComponent>
}

Changed

• Perf: use raw if instead of ts-pattern in the extractor (hot path)

0.17.5 - 2023-10-31

Fixed

• Fix issue where Solid.js styled factory fails with pattern styles includes a css variable (e.g. Divider)
• Fix issue where error is thrown for semantic tokens with raw values.
• Fix issue where using array syntax in config recipe generates invalid css
• Fix issue where cva composition in styled components doens't work as expected.

Changed

• Ensure dir exists before writing file for the panda cssgen / panda ship / panda analyze commands when specifying an outfile.

0.17.4 - 2023-10-30

Fixed

• Display semantic colors correctly in studio.
• Fix issue where types package was not built correctly.

0.17.3 - 2023-10-28

Fixed

• Fix regression in types due to incorrect package.json structure
• Fix issue in studio command where fs-extra imports could not be resolved.
• Fix an issue with the Postcss builder config change detection, which triggered unnecessary a rebuild of the artifacts.

CHanged

• Mark defineTokens and defineSemanticTokens with pure annotation to treeshake from bundle when using within component library.

0.17.2 - 2023-10-27

Fixed

Fix an issue with the CLI, using the dev mode instead of the prod mode even when installed from npm.

This resolves the following errors:

 Error: Cannot find module 'resolve.exports'

Error: Cannot find module './src/cli-main'

0.17.1 - 2023-10-26

Fixed

• Fix persistent error that causes CI builds to fail due to PostCSS plugin emitting artifacts in the middle of a build process.
• Fix issue where conditions don't work in semantic tokens when using template literal syntax.
• Fix issue in reset styles where button does not inherit color style
• Fix issue where FileSystem writes cause intermittent errors in different build contexts (Vercel, Docker). This was solved by limiting the concurrency using the p-limit library
• Fix issue where using scale css property adds an additional 'px'
• Fix issue where styled objects are sometimes incorrectly merged, leading to extraneous classnames in the DOM

Added

• Add --host and --port flags to studio.

Changed

• Change OmittedHTMLProps to be empty when using config.jsxStyleProps as minimal or none
• Remove export types from jsx when no jsxFramework configuration
• Extract identifier values coming from an EnumDeclaration member

Example:

enum Color {
  Red = 'red.400',
  Blue = 'blue.400',
}

const className = css({ color: Color.Red, backgroundColor: Color['Blue'] })

• Use predefined interfaces instead of relying on automatic TS type inference or type aliases. This should result in snappier

This should fix issues with the generation of typescript declaration (.d.ts) files when using @pandacss/xxx packages directly, such as:

src/config.ts(21,14): error TS2742: The inferred type of 'tokens' cannot be named without a reference to '../node_modules/@pandacss/types/src/shared'. This is likely not portable. A type annotation is necessa…

These changes are only relevant if you are directly using other Panda @pandacss/xxx packages than the @pandacss/dev.

0.17.0 - 2023-10-20

Fixed

• Fix an issue with the @layer tokens CSS declarations when using cssVarRoot with multiple selectors, like root, :host, ::backdrop

Added

• Improve support for styled element composition. This ensures that you can compose two styled elements together and the styles will be merged correctly.

const Box = styled('div', {
  base: {
    background: 'red.light',
    color: 'white',
  },
})

const ExtendedBox = styled(Box, {
  base: { background: 'red.dark' },
})

// <ExtendedBox> will have a background of `red.dark` and a color of `white`

Limitation: This feature does not allow compose mixed styled composition. A mixed styled composition happens when an element is created from a cva/inline cva, and another created from a config recipe.

• CVA or Inline CVA + CVA or Inline CVA = ✅
• Config Recipe + Config Recipe = ✅
• CVA or Inline CVA + Config Recipe = ❌

import { button } from '../styled-system/recipes'

const Button = styled('div', button)

// ❌ This will throw an error
const ExtendedButton = styled(Button, {
  base: { background: 'red.dark' },
})

• Export all types from @pandacss/types, which will also export all types exposed in the outdir/types. Also make the config.prefix object Partial so that each key is optional.
• Apply config.logLevel from the Panda config to the logger in every context. Fixes #1451
• Automatically add each recipe slots to the jsx property, with a dot notation

const button = defineSlotRecipe({
  className: 'button',
  slots: ['root', 'icon', 'label'],
  // ...
})

will have a default jsx property of: [Button, Button.Root, Button.Icon, Button.Label]

• Added a new type to extract variants out of styled components

import { StyledVariantProps } from '../styled-system/jsx'

const Button = styled('button', {
  base: { color: 'black' },
  variants: {
    state: {
      error: { color: 'red' },
      success: { color: 'green' },
    },
  },
})

type ButtonVariantProps = StyledVariantProps<typeof Button>
//   ^ { state?: 'error' | 'success' | undefined }

0.16.0 - 2023-10-15

Fixed

• Correct typings for Qwik components

Added

• Apply a few optmizations on the resulting CSS generated from panda cssgen command
• Add closed condition &:is([closed], [data-closed], [data-state="closed"])
• Adds a new --minimal flag for the CLI on the panda cssgen command to skip generating CSS for theme tokens, preflight, keyframes, static and global css

Thich means that the generated CSS will only contain the CSS related to the styles found in the included files.

Note that you can use a glob to override the config.include option like this: panda cssgen "src/**/*.css" --minimal

This is useful when you want to split your CSS into multiple files, for example if you want to split by pages.

Use it like this:

panda cssgen "src/**/pages/*.css" --minimal --outfile dist/pages.css

In addition to the optional glob that you can already pass to override the config.include option, the panda cssgen command now accepts a new {type} argument to generate only a specific type of CSS:

• preflight
• tokens
• static
• global
• keyframes

Note that this only works when passing an --outfile.

You can use it like this:

panda cssgen "static" --outfile dist/static.css

0.15.5 - 2023-10-4

Fixed

• Fix issue where unused recipes and slot recipes doesn't get treeshaken properly
• Fix issue with Promise.all where it aborts premature ine weird events. Switched to Promise.allSettled.
• Vue: Fix issue where elements created from styled factory does not forward DOM attributes and events to the underlying element.
• Vue: Fix regression in generated types
• Preact: Fix regression in generated types

0.15.4 - 2023-09-29

Fixed

• Fix preset merging, config wins over presets.
• Fix issues with class merging in the styled factory fn for Qwik, Solid and Vue.
• Fix static extraction of the Array Syntax when used with runtime conditions

Given a component like this:

function App() {
  return <Box py={[2, verticallyCondensed ? 2 : 3, 4]} />
}

the py value was incorrectly extracted like this:

 {
    "py": {
        "1": 2,
    },
},
{
    "py": {
        "1": 3,
    },
},

which would then generate invalid CSS like:

.paddingBlock\\\\:1_2 {
  1: 2px;
}

.paddingBlock\\\\:1_3 {
  1: 3px;
}

it's now correctly transformed back to an array:

{
  "py": {
-    "1": 2,
+   [
+       undefined,
+       2,
+   ]
  },
},
{
  "py": {
-    "1": 3,
+   [
+       undefined,
+       3,
+   ]
  },
},

which will generate the correct CSS

@media screen and (min-width: 40em) {
  .sm\\\\:py_2 {
    padding-block: var(--spacing-2);
  }

  .sm\\\\:py_3 {
    padding-block: var(--spacing-3);
  }
}

Added

Improved styled factory by adding a 3rd (optional) argument:

interface FactoryOptions<TProps extends Dict> {
  dataAttr?: boolean
  defaultProps?: TProps
  shouldForwardProp?(prop: string, variantKeys: string[]): boolean
}

• Setting dataAttr to true will add a data-recipe="{recipeName}" attribute to the element with the recipe name. This is useful for testing and debugging.

import { styled } from '../styled-system/jsx'
import { button } from '../styled-system/recipes'

const Button = styled('button', button, { dataAttr: true })

const App = () => (
  <Button variant="secondary" mt="10px">
    Button
  </Button>
)
// Will render something like <button data-recipe="button" class="btn btn--variant_purple mt_10px">Button</button>

• defaultProps allows you to skip writing wrapper components just to set a few props. It also allows you to locally override the default variants or base styles of a recipe.

import { styled } from '../styled-system/jsx'
import { button } from '../styled-system/recipes'

const Button = styled('button', button, {
  defaultProps: {
    variant: 'secondary',
    px: '10px',
  },
})

const App = () => <Button>Button</Button>
// Will render something like <button class="btn btn--variant_secondary px_10px">Button</button>

• shouldForwardProp allows you to customize which props are forwarded to the underlying element. By default, all props except recipe variants and style props are forwarded.

import { styled } from '../styled-system/jsx'
import { button } from '../styled-system/recipes'
import { isCssProperty } from '../styled-system/jsx'
import { motion, isValidMotionProp } from 'framer-motion'

const StyledMotion = styled(
  motion.div,
  {},
  {
    shouldForwardProp: (prop, variantKeys) =>
      isValidMotionProp(prop) || (!variantKeys.includes(prop) && !isCssProperty(prop)),
  },
)

0.15.3 - 2023-09-27

Fixed

• Fix issue where HMR does not work for Vue JSX factory and patterns
• Fix issue in template literal mode where media queries doesn't work
• Fix ExtendableUtilityConfig typings after a regression in 0.15.2 (due to #1410)
• Fix ExtendableTheme (specifically make the RecipeConfig Partial inside the theme: { extend: { ... } } object), same for slotRecipes

Added

• Add a new config.importMap option that allows you to specify a custom module specifier to import from instead of being tied to the outdir

You can now do things like leverage the native package.json imports:

export default defineConfig({
  outdir: './outdir',
  importMap: {
    css: '#panda/styled-system/css',
    recipes: '#panda/styled-system/recipes',
    patterns: '#panda/styled-system/patterns',
    jsx: '#panda/styled-system/jsx',
  },
})

Or you could also make your outdir an actual package from your monorepo:

export default defineConfig({
  outdir: '../packages/styled-system',
  importMap: {
    css: '@monorepo/styled-system',
    recipes: '@monorepo/styled-system',
    patterns: '@monorepo/styled-system',
    jsx: '@monorepo/styled-system',
  },
})

Working with tsconfig paths aliases is easy:

export default defineConfig({
  outdir: 'styled-system',
  importMap: {
    css: 'styled-system/css',
    recipes: 'styled-system/recipes',
    patterns: 'styled-system/patterns',
    jsx: 'styled-system/jsx',
  },
})

Changed

Automatically allow overriding config recipe compoundVariants styles within the styled JSX factory, example below

With this config recipe:

const button = defineRecipe({
  className: 'btn',
  base: { color: 'green', fontSize: '16px' },
  variants: {
    size: { small: { fontSize: '14px' } },
  },
  compoundVariants: [{ size: 'small', css: { color: 'blue' } }],
})

This would previously not merge the color property overrides, but now it does:

import { styled } from '../styled-system/jsx'
import { button } from '../styled-system/recipes'

const Button = styled('button', button)

function App() {
  return (
    <>
      <Button size="small" color="red.100">
        Click me
      </Button>
    </>
  )
}

• Before: btn btn--size_small text_blue text_red.100
• After: btn btn--size_small text_red.100

0.15.2 - 2023-09-26

Fixed

• Fix issue where studio uses studio config, instead of custom panda config.

Added

• Update supported panda config extensions
• Create custom partial types for each config object property

When bundling the outdir in a library, you usually want to generate type declaration files (d.ts). Sometimes TS will complain about types not being exported.

• Export all types from {outdir}/types/index.d.ts, this fixes errors looking like this:

src/components/Checkbox/index.tsx(8,7): error TS2742: The inferred type of 'Root' cannot be named without a reference to '../../../node_modules/@acmeorg/styled-system/types/system-types'. This is likely not portable. A type annotation is necessary.
src/components/Checkbox/index.tsx(8,7): error TS2742: The inferred type of 'Root' cannot be named without a reference to '../../../node_modules/@acmeorg/styled-system/types/csstype'. This is likely not portable. A type annotation is necessary.
src/components/Checkbox/index.tsx(8,7): error TS2742: The inferred type of 'Root' cannot be named without a reference to '../../../node_modules/@acmeorg/styled-system/types/conditions'. This is likely not portable. A type annotation is necessary.

• Export generated recipe interfaces from {outdir}/recipes/{recipeFn}.d.ts, this fixes errors looking like this:

src/ui/avatar.tsx (16:318) "AvatarRecipe" is not exported by "styled-system/recipes/index.d.ts", imported by "src/ui/avatar.tsx".
src/ui/card.tsx (2:164) "CardRecipe" is not exported by "styled-system/recipes/index.d.ts", imported by "src/ui/card.tsx".
src/ui/checkbox.tsx (19:310) "CheckboxRecipe" is not exported by "styled-system/recipes/index.d.ts", imported by "src/ui/checkbox.tsx".

• Export type ComponentProps from {outdir}/types/jsx.d.ts, this fixes errors looking like this:

 "ComponentProps" is not exported by "styled-system/types/jsx.d.ts", imported by "src/ui/form-control.tsx".

Changed

• Switch to interface for runtime types
• BREAKING CHANGE: Presets merging order felt wrong (left overriding right presets) and is now more intuitive (right overriding left presets)

Note: This is only relevant for users using more than 1 custom defined preset that overlap with each other.

Example:

const firstConfig = definePreset({
  theme: {
    tokens: {
      colors: {
        'first-main': { value: 'override' },
      },
    },
    extend: {
      tokens: {
        colors: {
          orange: { value: 'orange' },
          gray: { value: 'from-first-config' },
        },
      },
    },
  },
})

const secondConfig = definePreset({
  theme: {
    tokens: {
      colors: {
        pink: { value: 'pink' },
      },
    },
    extend: {
      tokens: {
        colors: {
          blue: { value: 'blue' },
          gray: { value: 'gray' },
        },
      },
    },
  },
})

// Final config
export default defineConfig({
  presets: [firstConfig, secondConfig],
})

Here's the difference between the old and new behavior:

{
  "theme": {
    "tokens": {
      "colors": {
        "blue": {
          "value": "blue"
        },
-        "first-main": {
-          "value": "override"
-        },
        "gray": {
-          "value": "from-first-config"
+          "value": "gray"
        },
        "orange": {
          "value": "orange"
        },
+        "pink": {
+            "value": "pink",
+        },
      }
    }
  }
}

0.15.1 - 2023-09-19

Fixed

• Fix an issue when wrapping a component with styled would display its name as styled.[object Object]
• Fix issue in css reset where number input field spinner still show.
• Fix issue where slot recipe breaks when slots is undefined

Added

• Reuse css variable in semantic token alias
• Add the property -moz-osx-font-smoothing: grayscale; to the reset.css under the html selector.
• Allow referencing tokens with the token() function in media queries or any other CSS at-rule.

import { css } from '../styled-system/css'

const className = css({
  '@media screen and (min-width: token(sizes.4xl))': {
    color: 'green.400',
  },
})

• Extract {fn}.raw as an identity fn

so this will now work:

import { css } from 'styled-system/css'

const paragraphSpacingStyle = css.raw({
  '&:not(:first-child)': { marginBlockEnd: '1em' },
})

export const proseCss = css.raw({
  maxWidth: '800px',
  '& p': {
    '&:not(:first-child)': { marginBlockStart: '1em' },
  },
  '& h1': paragraphSpacingStyle,
  '& h2': paragraphSpacingStyle,
})

• Use ECMA preset for ts-evaluator: This means that no other globals than those that are defined in the ECMAScript spec such as Math, Promise, Object, etc, are available but it allows for some basic evaluation of expressions like this:

import { cva } from '.panda/css'

const variants = () => {
  const spacingTokens = Object.entries({
    s: 'token(spacing.1)',
    m: 'token(spacing.2)',
    l: 'token(spacing.3)',
  })

  const spacingProps = {
    px: 'paddingX',
    py: 'paddingY',
  }

  // Generate variants programmatically
  return Object.entries(spacingProps)
    .map(([name, styleProp]) => {
      const variants = spacingTokens
        .map(([variant, token]) => ({ [variant]: { [styleProp]: token } }))
        .reduce((_agg, kv) => ({ ..._agg, ...kv }))

      return { [name]: variants }
    })
    .reduce((_agg, kv) => ({ ..._agg, ...kv }))
}

const baseStyle = cva({
  variants: variants(),
})

0.15.0 - 2023-09-13

Fixed

• Fix issue (#1365) with the unbox fn that removed nullish values, which could be useful for the Array Syntax

const className = css({
  color: ['black', undefined, 'orange', 'red'],
})

• Fix issue where slot recipe did not apply rules when variant name has the same key as a slot
• Fix issue with cva when using compoundVariants and not passing any variants in the usage (ex: button() with const button = cva({ ... }))
• Fix issue where hideFrom doesn't work due to incorrect breakpoint computation
• Fix issue where the satisfies would prevent an object from being extracted
• Fix an issue where some JSX components wouldn't get matched to their corresponding recipes/patterns when using Regex in the jsx field of a config, resulting in some style props missing.

Added

• Allow strings as zIndex and opacity tokens in order to support css custom properties

Changed

• Refactor: Prefer NativeElements type for vue jsx elements
• Move slot recipes styles to new recipes.slots layer so that classic config recipes will have a higher specificity
• Make the types suggestion faster (updated DeepPartial)

0.14.0 - 2023-09-05

Fixed

• Fix issue where pattern.raw(...) did not share the same signature as pattern(...)
• Fix issue where negative spacing tokens doesn't respect hash option
• Fix config.strictTokens: true issue where some properties would still allow arbitrary values
• Fix issue with the token() function in CSS strings that produced CSS syntax error when non-existing token were left unchanged (due to the .)

Before:

* {
  color: token(colors.magenta, pink);
}

Now:

* {
  color: token('colors.magenta', pink);
}

Added

• Add {svaFn}.raw function to get raw styles and allow reusable components with style overrides, just like with {cvaFn}.raw
• The utility transform fn now allow retrieving the token object with the raw value/conditions as currently there's no way to get it from there.
• Add generator:done hook to perform actions when codegen artifacts are emitted.
• Add each condition raw value information on hover using JSDoc annotation
• Add missing types (PatternConfig, RecipeConfig, RecipeVariantRecord) to solve a TypeScript issue (The inferred type of xxx cannot be named without a reference...)
• Add missing types (StyledComponents, RecipeConfig, PatternConfig etc) to solve a TypeScript issue (The inferred type of xxx cannot be named without a reference...) when generating declaration files in addition to using emitPackage: true
• Introduces deep nested colorPalettes for enhanced color management
• Previous color palette structure was flat and less flexible, now colorPalettes can be organized hierarchically for improved organization

Example: Define colors within categories, variants and states

const theme = {
  extend: {
    semanticTokens: {
      colors: {
        button: {
          dark: {
            value: 'navy',
          },
          light: {
            DEFAULT: {
              value: 'skyblue',
            },
            accent: {
              DEFAULT: {
                value: 'cyan',
              },
              secondary: {
                value: 'blue',
              },
            },
          },
        },
      },
    },
  },
}

You can now use the root button color palette and its values directly:

import { css } from '../styled-system/css'

export const App = () => {
  return (
    <button
      className={css({
        colorPalette: 'button',
        color: 'colorPalette.light',
        backgroundColor: 'colorPalette.dark',
        _hover: {
          color: 'colorPalette.light.accent',
          background: 'colorPalette.light.accent.secondary',
        },
      })}
    >
      Root color palette
    </button>
  )
}

Or you can use any deeply nested property (e.g. button.light.accent) as a root color palette:

import { css } from '../styled-system/css'

export const App = () => {
  return (
    <button
      className={css({
        colorPalette: 'button.light.accent',
        color: 'colorPalette.secondary',
      })}
    >
      Nested color palette leaf
    </button>
  )
}

Changed

• Change the typings for the css(...args) function so that you can pass possibly undefined values to it. This is mostly intended for component props that have optional values like cssProps?: SystemStyleObject and would use it like css({ ... }, cssProps)
• Change the css.raw function signature to match the one from css(), to allow passing multiple style objects that will be smartly merged.

0.13.1 - 2023-08-29

Fixed

• Fix issue where Panda does not detect styles after nested template in vue
• Fix issue where cva is undefined in preact styled factory

Added

• Allow .mts and .cts panda config extension
• Add forceConsistentTypeExtension config option for enforcing consistent file extension for emitted type definition files. This is useful for projects that use moduleResolution: node16 which requires explicit file extensions in imports/exports.

  If set to true and outExtension is set to mjs, the generated typescript .d.ts files will have the extension .d.mts.

0.13.0 - 2023-08-26

Fixed

• Fix issue where panda --minify does not work.
• Fix issue where defineTextStyle and defineLayerStyle return types are incompatible with config.theme type.
• Fix an issue with custom JSX components not finding their matching patterns.

Added

• Add support for minification in cssgen command.

0.12.2 - 2023-08-25

Fixed

• Fix bug in generated js code for atomic slot recipe where splitVariantProps didn't work without the first slot key.

Changed

• Change the css function signature to allow passing multiple style objects that will be smartly merged, and revert the cx method to string concatenation behaviour.

import { css, cx } from '../styled-system/css'

const App = () => {
  return (
    <>
-      <div className={cx(css({ mx: '3', paddingTop: '4' }), css({ mx: '10', pt: '6' }))}>
+      <div className={css({ mx: '3', paddingTop: '4' }, { mx: '10', pt: '6' })}>
        Will result in `class="mx_10 pt_6"`
      </div>
    </>
  )
}

• To design a component that supports style overrides, you can now provide the css prop as a style object, and it'll be merged correctly.

import { css } from '../styled-system/css'

export const Button = ({ css: cssProp = {}, children }) => {
  const className = css({ display: 'flex', alignItem: 'center', color: 'black' }, cssProp)
  return <button className={className}>{children}</button>
}

Then you can use the Button component like this:

import { Button, Thingy } from './Button'

export default function Page() {
  return (
    <Button css={{ color: 'pink', _hover: { color: 'red' } }}>
      will result in `class="d_flex items_center text_pink hover:text_red"`
    </Button>
  )
}

• Rename the {cvaFn}.resolve function to {cva}.raw for API consistency.
• Change the behaviour of {patternFn}.raw to return the resulting SystemStyleObject instead of the arguments passed in. This is to allow the css function to merge the styles correctly.

The new {cvaFn}.raw and {patternFn}.raw functions, will allow style objects to be merged as expected in any situation.

Pattern Example:

import { hstack } from '../styled-system/patterns'
import { css, cva } from '../styled-system/css'

export const Button = ({ css: cssProp = {}, children }) => {
  // using the flex pattern
  const hstackProps = hstack.raw({
    border: '1px solid',
    _hover: { color: 'blue.400' },
  })

  // merging the styles
  const className = css(hstackProps, cssProp)

  return <button className={className}>{children}</button>
}

CVA Example:

import { css, cva } from '../styled-system/css'

const buttonRecipe = cva({
  base: { display: 'flex', fontSize: 'lg' },
  variants: {
    variant: {
      primary: { color: 'white', backgroundColor: 'blue.500' },
    },
  },
})

export const Button = ({ css: cssProp = {}, children }) => {
  const className = css(
    // using the button recipe
    buttonRecipe.raw({ variant: 'primary' }),

    // adding style overrides (internal)
    { _hover: { color: 'blue.400' } },

    // adding style overrides (external)
    cssProp,
  )

  return <button className={className}>{props.children}</button>
}

0.12.1 - 2023-08-24

Fixed

• Fix issue where AnimationName type was generated wrongly if no keyframes were resolved in the config.

0.12.0 - 2023-08-24

Fixed

• Fix issue where styled factory does not respect union prop types like type Props = AProps | BProps
• Fix failed styled component for solid-js when using recipe

Added

• Add interactive flag to panda init command. This flag allows you to run the init command in interactive mode.

panda init -i

• Add defineUtility method. This method allows you to define custom utilities in your config.

import { defineUtility, defineConfig } from '@pandacss/dev'

const appearance = defineUtility({
  className: 'appearance',
  transform(value) {
    return { appearance: value, WebkitAppearance: value }
  },
})

export default defineConfig({
  utilities: {
    appearance,
  },
})

• Add animationName utility. This utility connects to your keyframes.

0.11.1 - 2023-08-16

Fixed

Add missing svg props types.

Added

Add new layers key to config, to make layers customizable.

Example:

In Config:

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  layers: {
    utilities: 'panda_utilities',
  },
})

In global css:

- @layer reset, base, tokens, recipes, utilities;
+ @layer reset, base, tokens, recipes, panda_utilities;

Doing this:

import { css } from '../styled-system/css'

const App = () => {
  return <div className={css({ color: 'blue.500' })} />
}

Results in:

@layer panda_utilities {
  .text_blue\.500 {
    color: var(--colors-blue-500);
  }
}

Changed

Make the cx smarter by merging and deduplicating the styles passed in.

Example:

import { css, cx } from '../styled-system/css'

export function Page() {
  return (
    <div class={cx(css({ mx: '3', paddingTop: '4' }), css({ mx: '10', pt: '6' }))}>Will result in "mx_10 pt_6"</div>
  )
}

0.11.0 - 2023-08-11

Fixed

• Fix regression where style property with multiple shorthand did not generate the correct className
• Normalize tsconfig path mapping to ensure consistency across platforms
• Fix issue where some style properties shows TS error when using !important

Added

• Add new visually hidden and bleed patterns.

  Bleed is a layout pattern is used to negate the padding applied to a parent container. You can apply an inline or block bleed to a child element, setting its value to match the parent's padding.

  import { css } from '../styled-system/css'
  import { bleed } from '../styled-system/patterns'
  
  export function Page() {
    return (
      <div class={css({ px: '6' })}>
        <div class={bleed({ inline: '6' })}>Welcome</div>
      </div>
    )
  }
  

  Visually hidden is a layout pattern used to hide content visually, but still make it available to screen readers.

  import { css } from '../styled-system/css'
  import { visuallyHidden } from '../styled-system/patterns'
  
  export function Checkbox() {
    return (
      <label>
        <input type="checkbox" class={visuallyHidden()}>
          I'm hidden
        </input>
        <span>Checkbox</span>
      </label>
    )
  }
  

• Add support for optional glob argument in the panda cssgen command. It is useful when you need to extract the css of specific pages in your application.

  This argument overrides the include config option.

  panda cssgen app/ecommerce/**/*.tsx -o ecommerce.css
  

• Added a new hook for when the final styles.css content has been generated. This is useful when you need to do something with the final CSS content.

  import { defineConfig } from '@pandacss/dev'
  
  export default defineConfig({
    hooks: {
      'generator:css'(file, content) {
        if (file === 'styles.css') {
          // do something with the final css content
        }
      },
    },
  })
  

Changed

• Removed the @pandacss/dev/astro entrypoint in favor of installing @pandacss/astro package
• Automatically inject the entry css @layer in @pandacss/astro removing the need to manually setup a css file.

0.10.0 - 2023-08-07

Fixed

• Reduce the size of the generated JS code by ~30% by optimizing the generated code.

  Check this PR to see the details.

• Fix issue in staticCss where recipe css generation does not work when recipe includes only base (no variants)
• Fix issue where opacity property is not connected to the opacity tokens

Added

Slot Recipes

Introduce new slot recipe features to define recipes that can be used to style composite or multi-part components easily.

• sva: the slot recipe version of cva
• defineSlotRecipe: the slot recipe version of defineRecipe

Atomic Slot Recipe

Use the sva function to define atomic slot recipes.

import { sva } from 'styled-system/css'

const button = sva({
  slots: ['label', 'icon'],
  base: {
    label: { color: 'red', textDecoration: 'underline' },
  },
  variants: {
    rounded: {
      true: {},
    },
    size: {
      sm: {
        label: { fontSize: 'sm' },
        icon: { fontSize: 'sm' },
      },
      lg: {
        label: { fontSize: 'lg' },
        icon: { fontSize: 'lg', color: 'pink' },
      },
    },
  },
  defaultVariants: {
    size: 'sm',
  },
})

export function App() {
  const btnClass = button({ size: 'lg', rounded: true })

  return (
    <button>
      <p class={btnClass.label}> Label</p>
      <p class={btnClass.icon}> Icon</p>
    </button>
  )
}

Config Slot Recipe

Use the defineSlotRecipe function to define slot recipes in your config.

import { defineConfig, defineSlotRecipe } from '@pandacss/dev'

export default defineConfig({
  theme: {
    slotRecipes: {
      button: defineSlotRecipe({
        className: 'button',
        slots: ['label', 'icon'],
        base: {
          label: { color: 'red', textDecoration: 'underline' },
        },
        variants: {
          rounded: {
            true: {},
          },
          size: {
            sm: {
              label: { fontSize: 'sm' },
              icon: { fontSize: 'sm' },
            },
            lg: {
              label: { fontSize: 'lg' },
              icon: { fontSize: 'lg', color: 'pink' },
            },
          },
        },
        defaultVariants: {
          size: 'sm',
        },
      }),
    },
  },
})

Here's how you can use the config slot recipe in your JSX code. The classnames generated by the slot recipe are added to the recipes cascade layer.

import { button } from 'styled-system/recipes'

export function App() {
  const btnClass = button({ size: 'lg', rounded: true })

  return (
    <button>
      <p class={btnClass.label}> Label</p>
      <p class={btnClass.icon}> Icon</p>
    </button>
  )
}

JSX Style Props

Add jsxStyleProps config option for controlling how JSX style props are handled in Panda. It helps to significantly reducing the bundle size of the generated JS code by using the jsxStyleProps config option.

This config option supports 3 values:

• all: All CSS properties can be used as JSX style props. This is the default value.

export default defineConfig({
  jsxStyleProps: 'all',
})

import { styled } from 'styled-system/jsx'

const Example = () => {
  // all CSS properties + css prop are allowed
  return <Box bg="red.400" color="white" css={{...}} />
}

• minimal: Only the css prop can be used as JSX style props. This reduced the generated JS bundle size by ~45%.

export default defineConfig({
  jsxStyleProps: 'minimal',
})

import { styled } from 'styled-system/jsx'

const Example = () => {
  // only the `css` prop is allowed
  return <Box css={{ bg: 'red.400', color: 'white' }} />
}

• none: No CSS properties can be used as JSX style props. This reduced the generated JS bundle size by ~48%.

export default defineConfig({
  jsxStyleProps: 'none',
})

Check this PR to see the details.

Changed

Update Panda preset conditions:

• _checked now supports [data-state=checked]
• _expanded now supports [data-state=expanded]
• _indeterminate now supports [data-state=indeterminate]
• _open now supports [data-open] and [data-state=open]

0.9.0 - 2023-07-28

Fixed

• Fix issue where extractor did not consider true and false branch when using tenary operator
• Fix issue where postcss plugin did not respect the cwd option in the panda config
• Fix issue where asset tokens generated invalid css variable

Added

Update the jsx property to be used for advanced tracking of custom pattern components.

import { Circle } from 'styled-system/jsx'

const CustomCircle = ({ children, ...props }) => {
  return <Circle {...props}>{children}</Circle>
}

To track the CustomCircle component, you can now use the jsx property.

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  patterns: {
    extend: {
      circle: {
        jsx: ['CustomCircle'],
      },
    },
  },
})

Changed

• BREAKING: Renamed the name property of a config recipe to className. This is to ensure API consistency and express the intent of the property more clearly.

export const buttonRecipe = defineRecipe({
-  name: 'button',
+  className: 'button',
  // ...
})

Update your config to use the new className property and run panda codegen --clean to update the generated code.

• BREAKING: Renamed the jsx property of a pattern to jsxName.

const hstack = definePattern({
-  jsx: 'HStack',
+  jsxName: 'HStack',
  // ...
})

Update your config to use the new jsxName property and run panda codegen --clean to update the generated code.

0.8.0 - 2023-07-25

Fixed

• Fix issue where panda init with jsxFramework flag generated invalid object due to missing comma.
• Fix issue where composite tokens in semantic tokens generated invalid css.
• Fix issue where extractor doesn't work reliably due to typescript module version mismatch.
• Fix issue where generated package json does not respect outExtension when emitPackage is true

Added

• Added new flags to the panda cssgen and panda ship command:

  • -w, --watch flag to watch for changes
  • -o shortcut for --outfile

• Introduce the new {fn}.raw() method to css, patterns and recipes. This function is an identity function and only serves as a hint for the extractor to extract the css.

  It can be useful, for example, in Storybook args or custom react props.

// mark the object as valid css for the extractor
<Button rootProps={css.raw({ bg: 'red.400' })} />

export const Funky: Story = {
  // mark this as a button recipe usage
  args: button.raw({
    visual: 'funky',
    shape: 'circle',
    size: 'sm',
  }),
}

Changed

• Improve virtual color processing to avoid generated unused css variables.
• Improve generated react jsx types to remove legacy ref
• Temporarily disable VSCode extension in .svelte or .vue files

0.7.0 - 2023-07-17

• Improve module detection and hot module reloading in the PostCSS plugin when external files are changed
• Fix issue where splitVariantProps in cva doesn't resolve the correct types
• Fix issue where zIndex tokens are not connected to zIndex utility

Changed

• Refactor transition utility to improve DX of adding transition. Transitions will now add a default transition property, timing function and duration. This allows you to add transitions with a single property.

<div className={css({ transition: 'background' })}>Content</div>

This will generate the following css:

.transition_background {
  transition-property: background, background-color;
  transition-timing-function: cubic-bezier(0.4, 0, 0.2, 1);
  transition-duration: 150ms;
}

  }
}

Changed

• Refactored all conditions to use :is selector to improve specificity and reduce the reliance on css order.

0.5.0 - 2023-06-26

Fixed

• Fix issue where escaping classname doesn't work when class starts with number.

Added

• Add support for tagged template literal version.

  This features is pure css approach to writing styles, and can be a great way to migrate from styled-components and emotion.

  Set the syntax option to template-literal in the panda config to enable this feature.

  // panda.config.ts
  export default defineConfig({
    //...
    syntax: 'template-literal',
  })
  

  For existing projects, you might need to run the panda codegen --clean

  You can also use the --syntax option to specify the syntax type when using the CLI.

  panda init -p --syntax template-literal
  

To get autocomplete for token variables, consider using the CSS Var Autocomplete extension.
