$ npm install @mdx-js/loader
@mdx-js/loader
webpack loader for MDX.
This package is a webpack loader to support MDX.
This integration is useful if you’re using webpack (or another tool that uses webpack, such as Next.js).
This integration can be combined with the Babel loader to support nonstandard JSX runtimes (such as Vue) or compile modern JavaScript features to ones your users support.
If you want to evaluate MDX code then the lower-level compiler (@mdx-js/mdx
)
can be used manually.
This package is ESM only:
Node 12+ is needed to use it and it must be import
ed instead of require
d.
npm:
npm install @mdx-js/loader@next
yarn:
yarn add @mdx-js/loader@next
Add something along these lines to your webpack.config.js
:
module.exports = {
module: {
// …
rules: [
// …
{
test: /\.mdx?$/,
use: [
{
loader: '@mdx-js/loader',
/** @type {import('@mdx-js/loader').Options} */
options: {}
}
]
}
]
}
}
See also ¶ Create React App (CRA), ¶ Next.js, and ¶ Vue CLI, if you’re using webpack through them, for more info.
This package exports a webpack plugin as the default export.
Source maps are supported based on how you configure webpack.
You do not need to pass options.SourceMapGenerator
.
options
options
are the same as compile
from @mdx-js/mdx
.
If you use modern JavaScript features you might want to use Babel through
babel-loader
to compile to code that works:
// …
use: [
// Note that Webpack runs right-to-left: `@mdx-js/loader` is used first, then
// `babel-loader`.
{loader: 'babel-loader', options: {}},
{
loader: '@mdx-js/loader',
/** @type {import('@mdx-js/loader').Options} */
options: {},
},
];
// …
webpack-cli
webpack-cli
doesn’t support loaders in ESM directly or even indirectly.
Because @mdx-js/mdx
itself is ESM, this means the @mdx-js/loader
loader
(even though it’s CJS) doesn’t work with webpack-cli
(it does work when using
the webpack API).
To use this loader with webpack-cli
, set the DISABLE_V8_COMPILE_CACHE=1
environment variable.
See this issue for details.
DISABLE_V8_COMPILE_CACHE=1 webpack
