Options Reference

loaders

type: Object

An object specifying Webpack loaders to use for language blocks inside *.vue files. The key corresponds to the lang attribute for language blocks, if specified. The default lang for each type is:
- <template>: html
- <script>: js
- <style>: css
For example, to use babel-loader and eslint-loader to process all <script> blocks:
```
// ...
vue: {
  loaders: {
    js: 'babel!eslint'
  }
}
```

autoprefixer

type: Boolean
default: true

Whether to enable autoprefixer for CSS inside *.vue files.

postcss

type: Array or Function or Object
Object format only supported in ^8.5.0

Specify custom PostCSS plugins to be applied to CSS inside *.vue files. If using a function, the function will called using the same loader context and should return an Array of plugins.
```
// ...
vue: {
  // note: do not nest the `postcss` option under `loaders`
  postcss: [require('postcss-cssnext')()],
  autoprefixer: false,
  loaders: {
    // ...
  }
}
```
This option can also be an object that contains options to be passed to the PostCSS processor. This is useful when you are using PostCSS projects that relies on custom parser/stringifiers:
```
postcss: {
  plugins: [...], // list of plugins
  options: {
    parser: sugarss // use sugarss parser
  }
}
```

cssSourceMap

type: Boolean
default: true

Whether to enable source maps for CSS. Disabling this can avoid some relative path related bugs in css-loader and make the build a bit faster.

Note this is automatically set to false if the devtool option is not present in the main Webpack config.

template

^8.4.0
type: Object

Pass options to the template rendering engine (via consolidate) if you are using a non-html templating language.

esModule

^9.4.3
type: Boolean
default: undefined

Whether to emit esModule compatible code. By default vue-loader will emit default export in commonjs format like module.exports = ..... When esModule is set to true, default export will be transpiled into exports.__esModule = true; exports = .... Useful for interoperating with transpiler other than Bable, like TypeScript.
