### `exportOnlyLocals`

Type: `Boolean`
Default: `false`

Export only locals.

**Useful** when you use **css modules** for pre-rendering (for example SSR).
For pre-rendering with `mini-css-extract-plugin` you should use this option instead of `style-loader!css-loader` **in the pre-rendering bundle**.
It doesn't embed CSS but only exports the identifier mappings.

**webpack.config.js**

```js
module.exports = {
module: {
rules: [
{
test: /\.css$/i,
loader: 'css-loader',
options: {
modules: {
exportOnlyLocals: true,
},
},
},
