Why Markdoc?

Markdoc allows you to enhance your Markdown with UI components. If you have existing content authored in Markdoc, this integration allows you to bring those files to your Astro project using content collections.

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 markdoc
# Using Yarn
yarn astro add markdoc
# Using PNPM
pnpm astro add markdoc

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/markdoc package using your package manager. If you're using npm or aren't sure, run this in the terminal:

npm install @astrojs/markdoc

Then, apply this integration to your astro.config.* file using the integrations property:

astro.config.mjs

import { defineConfig } from 'astro/config';
import markdoc from '@astrojs/markdoc';

export default defineConfig({
  // ...
  integrations: [markdoc()],
});

Usage

Markdoc files can only be used within content collections. Add entries to any content collection using the .mdoc extension:

src/content/docs/
  why-markdoc.mdoc
  quick-start.mdoc

Then, query for these files using the Content Collection APIs:

---
import { getEntryBySlug } from 'astro:content';

const entry = await getEntryBySlug('docs', 'why-markdoc');
const { Content } = await entry.render();
---

<!--Access frontmatter properties with `data`-->
<h1>{entry.data.title}</h1>
<!--Render Markdoc contents with the Content component-->
<Content />

📚 See the Astro Content Collection docs for more information.

Configuration

You can configure how your Markdoc content is rendered using props via the Content component. This component is returned by a content collection render() result.

config prop

The config prop accepts all Markdoc configuration options, including tags and variables.

This example defines a version variable to use within a why-markdoc.mdoc entry:

---
import { getEntryBySlug } from 'astro:content';

const entry = await getEntryBySlug('docs', 'why-markdoc');
const { Content } = await entry.render();
---

<Content
  config={{
    variables: {
      version: '0.0.1',
    }
  }}
/>

components prop

The components prop defines mappings from an HTML element name to an Astro or UI framework component (React, Vue, Svelte, etc).

:::note components does not support the client: directive for hydrating components. To embed client-side components, create a wrapper .astro file to import your component and apply a client: directive manually. :::

This example renders all h1 headings using a Title component:

---
import { getEntryBySlug } from 'astro:content';
import Title from '../components/Title.astro';

const entry = await getEntryBySlug('docs', 'why-markdoc');
const { Content } = await entry.render();
---

<Content
  components={{
    h1: Title,
  }}
/>
