Webpack

TODO: Add plugin documentation

MDX provides a built in webpack loader you need to install and configure for webpack projects.

Installation

npm install --save-dev @mdx-js/loader@next

Configuration

The loader needs to be used in tandem with the babel-loader. Most projects will typically already include this if you are using JSX syntax.

For webpack projects you can define the following webpack.config.js extension handler for .md and .mdx files:

module.exports = {
module: {
// ...
rules: [
// ...
{
test: /\.mdx?$/,
use: [
'babel-loader',
'@mdx-js/loader'
]
}
]
}
}

If you only want the loader for .mdx files you can change the regex to /\.mdx$/.

The transpiled output for MDX requires babel to be run. This is typically by adding in the babel-loader to run after the MDX loader. Webpack starts from the end of the loaders array and works backward, so it is important to follow the ordering above.

Babel configuration

You will also need to configure babel to support the language features that MDX uses. One way you can achieve that is using the following .babelrc at your project root.

{
"presets": [
"@babel/env",
"@babel/react"
]
}

And installing the dependencies:

npm install --save-dev @babel/preset-env @babel/preset-react
