Markdown Extensions

Header Anchors

Headers automatically get anchor links applied. Rendering of anchors can be configured using the markdown.anchor option.

Links

Internal Links

Internal links are converted to router link for SPA navigation. Also, every index.md contained in each sub-directory will automatically be converted to index.html, with corresponding URL /.

For example, given the following directory structure:

.
├─ index.md
├─ foo
│  ├─ index.md
│  ├─ one.md
│  └─ two.md
└─ bar
   ├─ index.md
   ├─ three.md
   └─ four.md

And providing you are in foo/one.md:

[Home](/) <!-- sends the user to the root index.md -->
[foo](/foo/) <!-- sends the user to index.html of directory foo -->
[foo heading](./#heading) <!-- anchors user to a heading in the foo index file -->
[bar - three](../bar/three) <!-- you can omit extention -->
[bar - three](../bar/three.md) <!-- you can append .md -->
[bar - four](../bar/four.html) <!-- or you can append .html -->

Page Suffix

Pages and internal links get generated with the .html suffix by default.

External Links

Outbound links automatically get target="_blank" rel="noopener noreferrer":

• vuejs.org
• VitePress on GitHub

Frontmatter

YAML frontmatter is supported out of the box:

---
title: Blogging Like a Hacker
lang: en-US
---

This data will be available to the rest of the page, along with all custom and theming components.

For more details, see Frontmatter.

Syntax Highlighting in Code Blocks

VitePress uses Prism to highlight language syntax in Markdown code blocks, using coloured text. Prism supports a wide variety of programming languages. All you need to do is append a valid language alias to the beginning backticks for the code block:

Input

```js
export default {
  name: 'MyComponent',
  // ...
}
```

Output

export default {
  name: 'MyComponent'
  // ...
}

Input

```html
<ul>
  <li v-for="todo in todos" :key="todo.id">
    {{ todo.text }}
  </li>
</ul>
```

Output

<ul>
  <li v-for="todo in todos" :key="todo.id">{{ todo.text }}</li>
</ul>

A list of valid languages is available on Prism’s site.

Line Highlighting in Code Blocks

Input

```js{4}
export default {
  data () {
    return {
      msg: 'Highlighted!'
    }
  }
}
```

Output

export default {
  data () {
    return {
      msg: 'Highlighted!'
    }
  }
}

In addition to a single line, you can also specify multiple single lines, ranges, or both:

• Line ranges: for example {5-8}, {3-10}, {10-17}
• Multiple single lines: for example {4,7,9}
• Line ranges and single lines: for example {4,7-13,16,23-27,40}

Input

```js{1,4,6-7}
export default { // Highlighted
  data () {
    return {
      msg: `Highlighted!
      This line isn't highlighted,
      but this and the next 2 are.`,
      motd: 'VitePress is awesome',
      lorem: 'ipsum',
    }
  }
}
```

Output

export default { // Highlighted
  data () {
    return {
      msg: `Highlighted!
      This line isn't highlighted,
      but this and the next 2 are.`,
      motd: 'VitePress is awesome',
      lorem: 'ipsum',
    }
  }
}

Line Numbers

You can enable line numbers for each code blocks via config:

module.exports = {
  markdown: {
    lineNumbers: true
  }
}

• Demo:

Import Code Snippets

You can import code snippets from existing files via following syntax:

<<< @/filepath

It also supports line highlighting:

<<< @/filepath{highlightLines}

Input

<<< @/snippets/snippet.js{2}

Code file

<<< @/snippets/snippet.js

Output

<<< @/snippets/snippet.js{2}

::: tip The value of @ corresponds to the source root. By default it's the VitePress project root, unless srcDir is configured. :::

You can also use a VS Code region to only include the corresponding part of the code file. You can provide a custom region name after a # following the filepath (snippet by default):

Input

<<< @/snippets/snippet-with-region.js{1}

Code file

<<< @/snippets/snippet-with-region.js

Output

<<< @/snippets/snippet-with-region.js#snippet{1}

Advanced Configuration

VitePress uses markdown-it as the Markdown renderer. A lot of the extensions above are implemented via custom plugins. You can further customize the markdown-it instance using the markdown option in .vitepress/config.js:

module.exports = {
  markdown: {
    // options for markdown-it-anchor
    anchor: { permalink: false },

    // options for markdown-it-toc
    toc: { includeLevel: [1, 2] },

    config: (md) => {
      // use more markdown-it plugins!
      md.use(require('markdown-it-xxx'))
    }
  }
}
