What is this?

This package implements the logic needed to integrate MDX into Volar. It implements a language plugin which makes Volar understand MDX files. It also implements a service plugin, which provides some additional functionality specific to MDX files.

When should I use this?

This package is intended for use by @mdx-js/language-server. It can also be used with other Volar integrations, such as @volar/monaco.

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install @mdx-js/language-service

In Deno with esm.sh:

import {
  createMdxLanguagePlugin,
  createMdxServicePlugin,
  resolveRemarkPlugins
} from 'https://esm.sh/@mdx-js/language-service'

In browsers with esm.sh:

<script type="module">
  import {
    createMdxLanguagePlugin,
    createMdxServicePlugin,
    resolveRemarkPlugins
  } from 'https://esm.sh/@mdx-js/language-service?bundle'
</script>

Use

This package exports functions for use with Volar. See the API documentation for each function to see what it does.

API

This package exports the identifiers createMdxLanguagePlugin, createMdxServicePlugin, and resolveRemarkPlugins. There is no default export.

createMdxLanguagePlugin([plugins][, checkMdx][, jsxImportSource])

Create a Volar language plugin to support MDX.

Parameters

• plugins (PluggableList, optional) — A list of remark syntax plugins. Only syntax plugins are supported. Transformers are unused.
• checkMdx (boolean, default: false) — If true, check MDX files strictly.
• jsxImportSource (string, default: react) — The JSX import source to use in the embedded JavaScript file.

Returns

A Volar language plugin to support MDX.

createMdxServicePlugin()

Create a Volar service module to support MDX. The service supports:

• Reporting diagnostics for parsing errors.
• Document drop support for images.
• Custom commands for toggling delete, emphasis, inlineCode, and strong text.

Parameters

This function doesn’t take any parameters.

Returns

The Volar service plugin for MDX files.

resolveRemarkPlugins(mdxConfig, resolvePlugin)

Resolve remark plugins from TypeScript’s parsed command line options.

Parameters

• mdxConfig (unknown) — The parsed command line options from which to resolve plugins.
• resolvePlugin (Function) — A function which takes a plugin name, and resolvs it to a remark plugin.

Returns

An array of resolved plugins, or undefined in case of an invalid configuration.

Compatibility

Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js and 16.0+. Our projects sometimes work with older versions, but this is not guaranteed.

Types

This package is fully typed with TypeScript.

Security

This package provides editor support for MDX files. Some editor features modify your source code, for example suggestions and automatic refactors. It is recommended to keep your source code under version control.
