vue-loader example

Example using vue-loader with Webpack.

Setup

# install dependencies
npm install

# serve with hot reload at localhost:8080
npm run dev

# build for production with minification
npm run build

# run unit tests
npm test

sass/scss&postcss

vue: {
  loaders: {
    js: 'babel!eslint',
    scss: 'style!css!sass!postcss'
  },
  postcss: [require('cssnext')(),require('postcss-nested')(),require('postcss-mixins')()]
}

<style scoped lang="scss">
.red{
  .test{
    color:blue !important;
    transform:rotateX(30deg) rotateY(30deg) translateY(50px);
  }
}
</style>

<!-- retult: -->
<style>
.red .test[_v-3def8906]{
    color: blue !important;
    -webkit-transform: rotateX(30deg) rotateY(30deg) translateY(50px);
    transform: rotateX(30deg) rotateY(30deg) translateY(50px);
}
</style>

ES2015 by Default

vue-loader automatically applies Babel transforms to the JavaScript inside *.vue components. Write ES2015 today!

The default Babel options used for Vue.js components are:

{
  presets: ['es2015'],
  plugins: ['transform-runtime']
}

If you wish to mofidy this, you can add a babel field in your webpack config, which will be merged with the default options. For example:

// webpack.config.js
module.exports = {
  // other configs...
  babel: {
    // enable stage-0 features, make sure to install
    // babel-preset-stage-0
    presets: ['es2015', 'stage-0'],
    plugins: ['transform-runtime']
  }
}

Using Per-file Pre-processors

If you only want to use pre-processors in a specific file, you can add an inline lang attribute to a language block:

<style lang="stylus">
  /* use stylus here */
</style>

Note you will have to install stylus-loader so that Webpack can handle the compilation. The lang attribute will be used to automatically locate the loader to use, and you can pass Webpack loader queries in it as well:

<style lang="sass?outputStyle=expanded">
  /* use sass here with expanded output */
</style>

Scoped CSS

Experimental. Requires vue-loader ^4.0.0

You can add the scoped attribute to a <style> block to make it scoped to the current component. A few things to take note:

1. You can include both scoped and non-scoped styles in the same component.

2. A child component's root node will be affected by both the parent's scoped CSS and the child's scoped CSS.

3. Partials are not affected by scoped styles.
