🍰 Dessert Box

A set of utilities to build UI and components with vanilla-extract.


⚠️ If you are not familiar with vanilla-extract, we recommend going trough their docs first and have a working setup before trying any of the dessert box packages.

$ npm install @dessert-box/react


A styled-components-like API to create components in your *.css.ts files. To use this, you can define your components

// styledComponents.css.ts
import { styled } from '@dessert-box/react';

export const StyledHeadline = styled('h1', {
  color: 'white',
  fontSize: '16px',
  fontWeight: 'bold
import { StyledHeadline } from './styledComponents.css.ts';

function App() {
  return (
    <StyledHeadline>I have 0 runtime styles 🤯</StyledHeadline>


A box component that will make consuming your sprinkles from a breeze. It provides a zero-CSS-runtime <Box /> component (similar to the one in Braid or Chakra).

Try it on CodeSandbox!

It works by consuming atoms created with vanilla-extract) and sprinkles. Shout out to the team at Seek for making these awesome libraries!

  1. Step 1, create your Box with your atoms created with sprinkles:
// Box.tsx
import { createBox } from '@dessert-box/react';
import { atoms } from './sprinkles.css';

const { Box } = createBox({
  // optional: pass your CSS reset className here
  // useful if you want to scope your reset to your Box element
  defaultClassName: 'resetClassName',

export default Box;
  1. Step 2, import it enjoy the sweetness:
// OtherFileOrComponent.tsx
import Box from './Box';

const MyComponent = () => {
  return <Box padding="large">What a sweet treat!</Box>;

Wondering how to use variants with this library? Check out the variants section.

Install the package:

$ npm install @dessert-box/react

Configure vanilla-extract and sprinkles and have your atoms ready:

// atoms.css.ts
import { defineProperties, createSprinkles } from '@vanilla-extract/sprinkles';

const space = {
  none: 0,
  small: 4,
  medium: 8,
  large: 16,

const colors = {
  primary: 'blue',
  // ...

const atomicStyles = defineProperties({
  conditions: {
    mobile: {},
    tablet: { '@media': 'screen and (min-width: 768px)' },
    desktop: { '@media': 'screen and (min-width: 1024px)' },
  properties: {
    padding: space,
    backgroundColor: colors,
    // ...
  // ...

export const atoms = createSprinkles(atomicStyles);

Check sprinkles docs for more context into how to create these atoms.

Now let's create our <Box /> using these atoms:

// Box.ts
import { createBox } from '@dessert-box/react';
import { atoms } from './sprinkles.css';

const { Box } = createBox({ atoms });

export default Box;
// otherFile.tsx
import Box from './Box';

const App = () => {
  return <Box padding="large">Hello</Box>;

Notice we can pass every property, shorthand, or condition we can normally pass to our atomsFn function. For example, we could leverage the conditions for responsive design we have here:

<Box padding={{ mobile: 'none', tablet: 'small', desktop: 'large' }} />

If you need to render a tag different than a div, you can use the as prop:

<Box as="a" href="" padding="small">
  Link to example

Escape Hatch

We have a way of specifying an arbitrary value (non design token) for any of your atoms properties like the following:

<Box padding="small" __margin="42px" __backgroundColor="yellow">
  Link to example

This is useful for those cases where we need to exit our system to accomplish something.

Try it on CodeSandbox!


The official @vanilla-extract/recipes package has an excelent API for dealing with variants, this can be combined with our Box component to create variant-based components:

NOTE: (Assuming you already have created your Box component following the example above).

  1. First define your recipe using the recipe function:
// Button.css.ts
import { recipe } from '@vanilla-extract/recipes';
import { atoms } from '../atoms.css';

export const buttonRecipe = recipe({
  variants: {
    kind: {
      primary: atoms({ background: 'blue50' }),
      secondary: atoms({ background: 'yellow' }),
    size: {
      md: atoms({ fontSize: 'large' }),
      lg: atoms({ fontSize: 'extraLarge' }),

export type ButtonVariants = Parameters<typeof buttonRecipe>[0];
  1. Then use the recipes function to create variants and apply them to your Box:
// Button.tsx
import { Box } from './Box';
import { buttonRecipe, ButtonVariants } from './Button.css';

type Props = {
  children: React.ReactNode;
} & ButtonVariants;

export const Button = ({
  size = 'md',
  kind = 'secondary',
}: Props) => {
  return (
    <Box as="button" className={buttonRecipe({ size, kind })}>

export default Button;

For more context, refer to @vanilla-extract/recipe or feel free to open an issue in this project if the integration is not working as you'd expect!


createBox(options: { atoms: AtomsFn, defaultClassName?: string })

Creates a <Box /> component that takes atoms at the root level.

import { createBox } from '@dessert-box/react';
import { atoms } from './atoms.css';

const Box = createBox({ atoms });

<Box padding="small" />;

createBoxWithAtomsProp(options: { atoms: AtomsFn, defaultClassName?: string })

Creates a <Box /> component that takes atoms as a prop called atoms.

import { createBoxWithAtomsProp } from '@dessert-box/react';
import { atoms } from './atoms.css';

const Box = createBoxWithAtomsProp({ atoms });

<Box atoms={{ padding: 'small' }} />;

Running the example app

Run npm install then npm run build in the root folder (the one with this README file).

Then move into the example folder cd example and run npm install and npm start.

How does it work?

This works by depending on build-time generated CSS by sprinkles, and then using the atomsFn function to lookup classNames in runtime. So it does have a runtime footprint, but should be pretty minimal. I'm still experimenting to see if it's possible to remove that, but other approaches may lead to other constraints or similar runtime.


  • Thanks to the team at Seek for vanilla-extract and sprinkles, this would not be possible without these great libs and the technical feats they accomplish.


  • What is a Box component?

It's a generic element that allows you to prototype fast and takes a variety of styling props (think of exposing a lot of CSS attributes as props on a component).

  • Why should I use a Box component?

There are many versions and flavors of a Box component, some are more flexible, while others are more restrictive. The Box in this library falls into the latter category (restrictive), and it's more geared towards being the a lower level API of your Design System (or serving as inspiration for it).

This Box component is meant to be used as a primitive for consuming design tokens, giving you a nice balance between flexibility and constraints. You can use it as an lower level API to implement your other components (Buttons, Card, Layout components, ...), and also as a prototyping and general usage component:

  • As a prototyping tool, it allows you to use all of your design tokens to generate new designs and evaluate if you need to iterate on your foundations, or to validate if they work for your use cases.
  • For general usage you can still have the guarantee that users of your system won't do anything impossible (e.g.: using a value that is not part of the design tokens) but still have a productive experience working on UI.
