Markdown Tools

createEmbedRuleBlock(md, options)

Creates an embed rule block for parsing @[type info](source) syntax in markdown.

import { createEmbedRuleBlock } from 'vitepress-plugin-toolkit'

createEmbedRuleBlock(md, {
  type: 'video',
  meta: (info, source) => ({ src: source, title: info }),
  content: meta => `<video src="${meta.src}" title="${meta.title}"></video>`,
})

Usage in markdown:

@[video My Video](https://example.com/video.mp4)

Options:

Parameter	Type	Description
type	string	Embed type identifier, e.g. 'video', 'embed'
name	string	Optional, custom token name, defaults to embed_${type}
meta	(info: string, source: string) => Meta	Parses info and source into a metadata object
content	(meta: Meta, env: MarkdownEnv) => string	Optional, generates HTML content from metadata

createContainerPlugin(md, type, options?)

Creates a custom container plugin based on markdown-it-container. Content is processed normally by markdown-it.

import { createContainerPlugin } from 'vitepress-plugin-toolkit'

md.use(createContainerPlugin, 'tip', {
  before: info => `<div class="tip">${info}`,
  after: () => '</div>',
})

Usage in markdown:

::: tip Note
This is a tip message
:::

Options:

Parameter	Type	Description
before	(info: string, ...args: RenderRuleParams) => string	Optional, callback for container opening tag
after	(info: string, ...args: RenderRuleParams) => string	Optional, callback for container closing tag

createContainerSyntaxPlugin(md, type, render?)

Creates a custom container syntax plugin. Content inside the container is NOT processed by markdown-it, but passed entirely to a custom render function.

import { createContainerSyntaxPlugin } from 'vitepress-plugin-toolkit'

createContainerSyntaxPlugin(md, 'chart', (tokens, idx) => {
  const { content, meta } = tokens[idx]
  return `<div class="chart">${content}</div>`
})

VitePress Config Utilities

getVitepressConfig()

Retrieves the current VitePress site configuration from globalThis.VITEPRESS_CONFIG.

import { getVitepressConfig } from 'vitepress-plugin-toolkit'

const config = getVitepressConfig()
console.log(config.userConfig.title)

createLocales(builtinLocales, userLocales?)

Creates a locales configuration by merging built-in locale data with user-provided locale data.

import { createLocales } from 'vitepress-plugin-toolkit'

const locales = createLocales(
  [
    [['en', 'en-US'], { title: 'English' }],
    [['zh', 'zh-CN'], { title: '中文' }],
  ],
  { zh: { title: 'My Site' } },
)

resolveRouteLink(url, env)

Resolves markdown links according to VitePress routing rules:

• External links returned as-is
• Absolute paths prefixed with site base
• Relative .md links converted to .html based on cleanUrls
• index.md collapsed to directory path
• Hash fragments auto-slugified

import { resolveRouteLink } from 'vitepress-plugin-toolkit'

resolveRouteLink('./guide.md', env) // -> './guide.html' (depends on cleanUrls)

getLocaleWithPath(path)

Returns the language code and locale prefix for a given path.

import { getLocaleWithPath } from 'vitepress-plugin-toolkit'

getLocaleWithPath('/zh/guide/') // { lang: 'zh-CN', locale: '/zh/' }
getLocaleWithPath('/guide/')   // { lang: 'en', locale: '' } (root)

Vite Plugin

iconPlugin(icons)

Creates a Vite plugin that registers SVG icons as CSS custom properties (--icon), generating CSS selectors like .vpi-<name>.

import { iconPlugin } from 'vitepress-plugin-toolkit'

defineConfig({
  vite: {
    plugins: [
      iconPlugin([
        { name: 'github', svg: '<svg>...</svg>' },
        { name: 'twitter', svg: '<svg>...</svg>' },
      ]),
    ],
  },
})

Display icons by adding class names:

<span class="vpi-github"></span>

Node Utility Functions

resolveAttrs(info) / resolveAttr(info, key)

Parses an attribute string into an object, or extracts a single attribute value. Supports key="value" format and boolean attributes (disabled, etc.).

import { resolveAttrs, resolveAttr } from 'vitepress-plugin-toolkit'

resolveAttrs('width="100" height="50"') // { width: '100', height: '50' }
resolveAttr('width="100" height="50"', 'width') // '100'

stringifyAttrs(attrs, withUndefinedOrNull?, forceStringify?)

Stringifies an attributes object into an HTML attribute string. Automatically handles Boolean, Number, and String types.

import { stringifyAttrs } from 'vitepress-plugin-toolkit'

stringifyAttrs({ width: 100, disabled: true })
// ' :width="100" disabled'

parseRect(str, unit?)

Parses a size string, appending a unit (default px) to bare numbers.

import { parseRect } from 'vitepress-plugin-toolkit'

parseRect('100')    // '100px'
parseRect('50%')    // '50%'
parseRect('200', 'rpx') // '200rpx'

slugify(str)

Generates a URL-friendly slug, removing accents, control characters, and special characters, and merging consecutive separators.

import { slugify } from 'vitepress-plugin-toolkit'

slugify('Hello World!') // 'hello-world'

genHash(data, length?)

Generates a SHA-256 hash for any data, with optional truncation length.

import { genHash } from 'vitepress-plugin-toolkit'

genHash('hello')      // full SHA-256 hash
genHash({ a: 1 }, 8)  // 8-character hash

treatAsHtml(filename)

Determines whether a file should be treated as an HTML route (not a static asset).

import { treatAsHtml } from 'vitepress-plugin-toolkit'

treatAsHtml('about')   // true
treatAsHtml('logo.png') // false

createLogger(prefix, defaultLevel?)

Creates a formatted logger instance with colored labels and timestamps.

import { createLogger } from 'vitepress-plugin-toolkit'

const logger = createLogger('my-plugin', 'info')
logger.info('Build started')
logger.warn('Deprecated feature used')
logger.debug('Verbose details', 'debug')

Constants

import {
  isBuild,           // Whether building for production
  isDev,             // Whether in development mode
  EXTENSION_VIDEOS,  // Browser-supported video file extensions
  EXTENSION_IMAGES,  // Browser-supported image file extensions
  EXTENSION_AUDIOS,  // Browser-supported audio file extensions
} from 'vitepress-plugin-toolkit'

Client API

Vue Components

Composables

useSize(el, options, extraHeight?)

Reactive size calculation based on width, height, and aspect ratio options. Automatically listens for window resize and orientationchange events.

import { useSize } from 'vitepress-plugin-toolkit/client'

const el = ref<HTMLElement>()
const { width, height, resize } = useSize(
  el,
  toRefs({ width: '100%', ratio: '16:9' }),
)

useZoomAndDrag(parentEl)

Provides zoom and drag interaction for a content stage, supporting mouse drag, touch drag, and pinch-to-zoom.

const stageEl = ref<HTMLDivElement>()
const { actorStyle, zoom, zoomIn, zoomOut, resetZoom, reset } = useZoomAndDrag(stageEl)
