# pnpm
pnpm add @borstihd/vue-custom-tooltip

# yarn
yarn add @borstihd/vue-custom-tooltip

Usage

Global Registration (Plugin)

import { VueCustomTooltip } from '@borstihd/vue-custom-tooltip'
import { createApp } from 'vue'
import App from './App.vue'
import '@borstihd/vue-custom-tooltip/dist/style.css'

const app = createApp(App)
app.use(VueCustomTooltip)
app.mount('#app')

Global Registration with Custom Defaults

You can configure global defaults for all tooltips in your application:

import { VueCustomTooltip } from '@borstihd/vue-custom-tooltip'
import { createApp } from 'vue'
import App from './App.vue'
import '@borstihd/vue-custom-tooltip/dist/style.css'

const app = createApp(App)

// Configure global defaults for all tooltips
app.use(VueCustomTooltip, {
  globalConfig: {
    position: 'top', // Default position for all tooltips
    trigger: 'hover', // Default trigger behavior
    showDelay: 200, // Default show delay (ms)
    hideDelay: 150, // Default hide delay (ms)
    dark: true, // Force dark mode for all tooltips
    showArrow: true, // Show arrow by default
    offset: 12, // Default offset from trigger
    maxWidth: '300px', // Default max width
  }
})

app.mount('#app')

How it works:

• Global configuration provides default values for all tooltips
• Individual tooltip props override global configuration
• Priority order: Component Props > Global Config > Built-in Defaults

Example:

<template>
  <!-- Uses global config (position: 'top', showDelay: 200) -->
  <Tooltip content="Uses global defaults">
    <button>Default</button>
  </Tooltip>

  <!-- Overrides position, but uses global showDelay: 200 -->
  <Tooltip content="Custom position" position="bottom">
    <button>Custom Position</button>
  </Tooltip>

  <!-- Overrides both position and showDelay -->
  <Tooltip content="All custom" position="right" :show-delay="0">
    <button>All Custom</button>
  </Tooltip>
</template>

Component Usage

<script setup lang="ts">
import { Tooltip } from '@borstihd/vue-custom-tooltip'
import '@borstihd/vue-custom-tooltip/dist/style.css'
</script>

<template>
  <!-- Basic usage -->
  <Tooltip content="Simple tooltip text">
    <button>Hover me</button>
  </Tooltip>

  <!-- With custom positioning -->
  <Tooltip content="I'm on the right" position="right">
    <button>Right tooltip</button>
  </Tooltip>

  <!-- Click trigger -->
  <Tooltip content="Click to toggle" trigger="click">
    <button>Click me</button>
  </Tooltip>

  <!-- Rich content with slots -->
  <Tooltip>
    <button>Rich content</button>
    <template #content>
      <div class="space-y-2">
        <h4>Rich Tooltip</h4>
        <p>With <strong>formatted</strong> content</p>
      </div>
    </template>
  </Tooltip>
</template>

Directive Usage

The v-tooltip directive also respects global configuration. Any modifiers or configuration you pass to the directive will override the global defaults.

<script setup lang="ts">
import { vTooltip } from '@borstihd/vue-custom-tooltip'
import '@borstihd/vue-custom-tooltip/dist/style.css'
</script>

<template>
  <!-- Simple text (uses global config if set) -->
  <button v-tooltip="'Tooltip text'">
    Hover me
  </button>

  <!-- With modifiers (overrides global config) -->
  <button v-tooltip.top.click="'Click me'">
    Top tooltip on click
  </button>

  <!-- With configuration object (overrides global config) -->
  <button v-tooltip="{ content: 'Custom', position: 'right', showDelay: 0 }">
    Fast tooltip
  </button>

  <!-- Available modifiers -->
  <button v-tooltip.top="'Top'">
    Top
  </button>
  <button v-tooltip.bottom="'Bottom'">
    Bottom
  </button>
  <button v-tooltip.left="'Left'">
    Left
  </button>
  <button v-tooltip.right="'Right'">
    Right
  </button>
  <button v-tooltip.auto="'Auto'">
    Auto-position
  </button>

  <!-- Trigger modifiers -->
  <button v-tooltip.hover="'Hover only'">
    Hover
  </button>
  <button v-tooltip.focus="'Focus only'">
    Focus
  </button>
  <button v-tooltip.both="'Hover and focus'">
    Both
  </button>
  <button v-tooltip.click="'Click to toggle'">
    Click
  </button>

  <!-- Timing modifiers -->
  <button v-tooltip.fast="'Fast'">
    Fast (10ms delay)
  </button>
  <button v-tooltip.slow="'Slow'">
    Slow (1000ms delay)
  </button>
</template>

API

Component Props

Prop	Type	Default	Description
content	string	undefined	Text content for the tooltip
position	'top' | 'bottom' | 'left' | 'right' | 'auto'	'auto'	Position relative to trigger
trigger	'hover' | 'focus' | 'both' | 'click'	'both'	How to trigger the tooltip
showDelay	number	100	Delay before showing (ms)
hideDelay	number	100	Delay before hiding (ms)
disabled	boolean	false	Disable the tooltip
maxWidth	string	'250px'	Maximum width of tooltip
tooltipClass	string	''	Custom CSS class
showArrow	boolean	true	Show arrow pointer
offset	number	8	Offset from trigger (px)
dark	'auto' | boolean	'auto'	Dark mode behavior (see below)

Dark Mode Options

The dark prop controls the tooltip's appearance in dark environments:

• 'auto' (default): Automatically detects dark mode using both CSS prefers-color-scheme: dark media query and Tailwind's .dark class. This is the recommended setting for most use cases.
• true: Always use dark theme, regardless of system or class-based settings
• false: Always use light theme, regardless of system or class-based settings

Examples:

<!-- Auto-detect (recommended) - works with both OS dark mode and Tailwind -->
<Tooltip content="Auto dark mode" dark="auto">
  <button>Hover me</button>
</Tooltip>

<!-- Always dark -->
<Tooltip content="Always dark" :dark="true">
  <button>Dark tooltip</button>
</Tooltip>

<!-- Always light -->
<Tooltip content="Always light" :dark="false">
  <button>Light tooltip</button>
</Tooltip>

Component Slots

Slot	Description
default	The trigger element
content	Rich content for the tooltip (alternative to content prop)

Directive Modifiers

Modifier	Description
.top	Position tooltip on top
.bottom	Position tooltip on bottom
.left	Position tooltip on left
.right	Position tooltip on right
.auto	Auto-detect best position
.hover	Show on hover only
.focus	Show on focus only
.both	Show on hover and focus

Advanced Configuration

Runtime Configuration Management

You can programmatically manage global configuration at runtime:

import {
  getTooltipGlobalConfig,
  resetTooltipGlobalConfig,
  setTooltipGlobalConfig
} from '@borstihd/vue-custom-tooltip'

// Set or update global configuration
setTooltipGlobalConfig({
  position: 'bottom',
  showDelay: 300,
  dark: true
})

// Get current global configuration
const currentConfig = getTooltipGlobalConfig()
console.log(currentConfig)

// Reset to no global configuration
resetTooltipGlobalConfig()

TypeScript

The package includes full TypeScript support with type definitions for props, slots, globally registered components and directives.

Type Imports

import type { TooltipProps, TooltipSlots } from '@borstihd/vue-custom-tooltip'

Global Component Types

When you install the plugin using app.use(VueCustomTooltip), the Tooltip component is automatically registered globally and TypeScript will recognize it in your templates with full autocomplete and type checking.

No additional configuration needed! The package includes Vue component type augmentation, so your IDE will provide:

• ✅ Prop autocomplete for <Tooltip>
• ✅ Type checking for prop values
• ✅ IntelliSense documentation

Example:

<template>
  <!-- TypeScript knows about these props and validates them -->
  <Tooltip
    content="Hello"
    position="top"
    :show-delay="200"
  >
    <button>Hover me</button>
  </Tooltip>
</template>

Note for local imports: If you import the component directly instead of using the plugin, you'll need to import it explicitly:

<script setup lang="ts">
import { Tooltip } from '@borstihd/vue-custom-tooltip'
</script>

<template>
  <Tooltip content="Hello">
    <button>Hover me</button>
  </Tooltip>
</template>

Global Directive Types

The v-tooltip directive is also fully typed when you install the plugin. TypeScript will recognize the directive and validate its modifiers.

Available modifiers with full type support:

• ✅ Position modifiers: .top, .bottom, .left, .right, .auto
• ✅ Trigger modifiers: .hover, .focus, .both, .click
• ✅ Timing modifiers: .fast, .slow
• ✅ Theme modifiers: .dark, .light

Example:

<template>
  <!-- TypeScript validates these modifiers -->
  <button v-tooltip.top.fast="'Quick tooltip'">
    Hover me
  </button>

  <!-- Object syntax with full type checking -->
  <button v-tooltip="{ content: 'Hello', position: 'right' }">
    Click me
  </button>
</template>

Styling

The tooltip uses CSS custom properties for theming. You can customize the appearance by overriding these variables:

:root {
  /* Focus outline color for keyboard navigation */
  --vct-focus-color: #3b82f6;

  /* Tooltip text color */
  --vct-text-color: #374151;

  /* Tooltip background color */
  --vct-background: #ffffff;

  /* Tooltip border color */
  --vct-border-color: #d1d5db;

  /* Tooltip border radius */
  --vct-border-radius: 8px;

  /* Dark mode colors (optional, used when dark="auto" or dark={true}) */
  --vct-text-color-dark: #e0e0e0;
  --vct-background-dark: #2a2a2a;
  --vct-border-color-dark: #444444;
}

Custom Theme Example

/* Dark theme example */
:root {
  --vct-text-color: #e0e0e0;
  --vct-background: #2a2a2a;
  --vct-border-color: #444444;
  --vct-border-radius: 12px;
  --vct-focus-color: #60a5fa;
}

/* Or scope to specific components */
.my-custom-tooltips {
  --vct-background: #1e40af;
  --vct-text-color: white;
  --vct-border-color: #1e3a8a;
}

Tailwind CSS Integration

The tooltip automatically detects Tailwind's dark mode when using dark="auto" (default):

<script setup lang="ts">
import { Tooltip } from '@borstihd/vue-custom-tooltip'
</script>

<template>
  <!-- Automatically works with Tailwind's dark mode -->
  <Tooltip content="I automatically adapt to Tailwind's dark mode!">
    <button>Hover me</button>
  </Tooltip>
</template>

How it works:

• When dark="auto" (default), the tooltip responds to both the system's prefers-color-scheme: dark and Tailwind's .dark class
• No additional configuration needed - just ensure your tailwind.config.js uses class-based dark mode:

module.exports = {
  darkMode: 'class', // or 'selector'
  // ... rest of config
}

Note: The package is completely independent and does not rely on any other UI library (like PrimeVue, Element Plus, or similar). All CSS variables have sensible defaults, so the tooltips work out-of-the-box without any configuration.

Accessibility

• ✅ Keyboard navigation (Tab, Escape)
• ✅ Screen reader compatible
• ✅ ARIA attributes
• ✅ Focus management
• ✅ Reduced motion support
• ✅ High contrast mode support
