@astrojs/mdx 📝
This Astro integration enables the usage of MDX components and allows you to create pages as .mdx
files.
Why MDX?
MDX allows you to use variables, JSX expressions and components within Markdown content in Astro. If you have existing content authored in MDX, this integration allows you to bring those files to your Astro project.
Installation
Quick Install
The astro add
command-line tool automates the installation for you. Run one of the following commands in a new terminal window. (If you aren't sure which package manager you're using, run the first command.) Then, follow the prompts, and type "y" in the terminal (meaning "yes") for each one.
# Using NPM
npx astro add mdx
# Using Yarn
yarn astro add mdx
# Using PNPM
pnpm astro add mdx
If you run into any issues, feel free to report them to us on GitHub and try the manual installation steps below.
Manual Install
First, install the @astrojs/mdx
package using your package manager. If you're using npm or aren't sure, run this in the terminal:
npm install @astrojs/mdx
Then, apply this integration to your astro.config.*
file using the integrations
property:
astro.config.mjs
import { defineConfig } from 'astro/config';
import mdx from '@astrojs/mdx';
export default defineConfig({
// ...
integrations: [mdx()],
});
Editor Integration
VS Code supports Markdown by default. However, for MDX editor support, you may wish to add the following setting in your VSCode config. This ensures authoring MDX files provides a Markdown-like editor experience.
"files.associations": {
"*.mdx": "markdown"
}
Usage
With the Astro MDX integration, you can add MDX pages to your project by adding .mdx
files within your src/pages/
directory. You can also import .mdx
files into .astro
files.
Astro's MDX integration adds extra features to standard MDX, including Markdown-style frontmatter. This allows you to use most of Astro's built-in Markdown features like a special frontmatter layout
property and a property for marking a page as a draft.
See how MDX works in Astro with examples in our Markdown & MDX guide.
Visit the MDX docs to learn about using standard MDX features.
Configuration
Once the MDX integration is installed, no configuration is necessary to use .mdx
files in your Astro project.
You can configure how your MDX is rendered with the following options:
Options inherited from Markdown config
All markdown
configuration options except drafts
can be configured separately in the MDX integration. This includes remark and rehype plugins, syntax highlighting, and more. Options will default to those in your Markdown config (see the extendMarkdownConfig
option to modify this).
:::note There is no separate MDX configuration for including pages marked as draft in the build. This Markdown setting will be respected by both Markdown and MDX files and cannot be overridden for MDX files specifically. :::
astro.config.mjs
import { defineConfig } from 'astro/config';
import mdx from '@astrojs/mdx';
import remarkToc from 'remark-toc';
import rehypeMinifyHtml from 'rehype-minify-html';
export default defineConfig({
integrations: [
mdx({
syntaxHighlight: 'shiki',
shikiConfig: { theme: 'dracula' },
remarkPlugins: [remarkToc],
rehypePlugins: [rehypeMinifyHtml],
remarkRehype: { footnoteLabel: 'Footnotes' },
gfm: false,
})
]
})
:::caution MDX does not support passing remark and rehype plugins as a string. You should install, import, and apply the plugin function instead. :::
📚 See the Markdown Options reference for a complete list of options.
extendMarkdownConfig
- Type:
boolean
- Default:
true
MDX will extend your project's existing Markdown configuration by default. To override individual options, you can specify their equivalent in your MDX configuration.
For example, say you need to disable GitHub-Flavored Markdown and apply a different set of remark plugins for MDX files. You can apply these options like so, with extendMarkdownConfig
enabled by default:
astro.config.mjs
import { defineConfig } from 'astro/config';
import mdx from '@astrojs/mdx';
export default defineConfig({
markdown: {
syntaxHighlight: 'prism',
remarkPlugins: [remarkPlugin1],
gfm: true,
},
integrations: [
mdx({
// `syntaxHighlight` inherited from Markdown
// Markdown `remarkPlugins` ignored,
// only `remarkPlugin2` applied.
remarkPlugins: [remarkPlugin2],
// `gfm` overridden to `false`
gfm: false,
})
]
});
You may also need to disable markdown
config extension in MDX. For this, set extendMarkdownConfig
to false
:
astro.config.mjs
import { defineConfig } from 'astro/config';
import mdx from '@astrojs/mdx';
export default defineConfig({
markdown: {
remarkPlugins: [remarkPlugin1],
},
integrations: [
mdx({
// Markdown config now ignored
extendMarkdownConfig: false,
// No `remarkPlugins` applied
})
]
});
recmaPlugins
These are plugins that modify the output estree directly. This is useful for modifying or injecting JavaScript variables in your MDX files.
We suggest using AST Explorer to play with estree outputs, and trying estree-util-visit
for searching across JavaScript nodes.
Examples
- The Astro MDX starter template shows how to use MDX files in your Astro project.
