Vue separate files Webpack loader

Creates .vue single file components on fly, allowing you to have clean separated components files and still enjoy
advantages of vue-loader.

• Handles files by their names (instead of loading all files in folder) and creates .vue file on fly (instead of
  creating physical one)
• Allows to add custom attributes through options.global, options[FILE_TYPE] and options[TAG_NAME]
• Allows to handle vue custom blocks
• Allows to have scoped style by component
• Allows to define support for other file extensions / types
• Allows to define test condition for loader (eg. .vue., etc.)

Based on these ideas vue-builder-webpack-plugin and
vue-separate-files-loader.

Example application

See this repository.

Install

 npm i -D vue-separate-files-webpack-loader

or

 yarn add -D vue-separate-files-webpack-loader

Usage

VueLoader v15 onward
As vue-loader introduced mandatory plugin usage in version 15,
which updates webpack rules, there's need to use plugin provided by vue-separate-files-webpack-loader/plugin in order to work
with this version onward.

VueLoader v14 and below
Just don't include vue-separate-files-webpack-loader/plugin to your webpack configuration.

Configuration

Simple

 // webpack.config.js

const VueSeparateLoaderPlugin = require('vue-separate-files-webpack-loader/plugin')

module.exports = {
  module: {
    rules: [
      {
        // notice modified file test
        test: /\.vue\./,
        use: [
          {
            loader: 'vue-loader'
          },
          {
            loader: 'vue-separate-files-webpack-loader'
          }
        ]
      }
    ]
  },
  plugins: [
    // mandatory from VueLoader v15 onward
    // has to be added AFTER "new VueLoaderPlugin()"
    // available options below
    new VueSeparateLoaderPlugin(options),
  ]
}

Complex (with options definition)

 // webpack.config.js

const VueSeparateLoaderPlugin = require('vue-separate-files-webpack-loader/plugin')

module.exports = {
  module: {
    rules: [
      // regular VueLoader definition
      // use it when you want to use both component styles, otherwise you may omit it
      // ie SFC: Component.vue and Separated: Component.vue.html Component.vue.js
      {
        test: /\.vue$/,
        loader: 'vue-loader'
      },
      // VueSeparateFilesWebpackLoader definition
      {
        // notice modified file test
        test: /\.vue\./,
        use: [
          {
            loader: 'vue-loader',
            options: {/* usual vue-loader options */}
          },
          {
            loader: 'vue-separate-files-webpack-loader',
            options: {
              // add support for other file types
              types: {
                script: '\\.re$',
                template: '\\.hb$'
              },
              global: {
                // all files will have these
                attr: 'value'
              },
              sass: {
                // only SASS files will have these
                attr: 'value'
              },
              style: {
                // only style files will have these
                attr: 'value'
              }
            }
          }
        ]
      }
    ]
  },
  plugins: [
    // mandatory from VueLoader v15 onward
    // has to be added AFTER "new VueLoaderPlugin()"
    // available options below
    new VueSeparateLoaderPlugin(options),
  ]
}

With VueCLI 3 generated project

 // vue.config.js

const VueSeparateFilesWebpackLoaderPlugin = require('vue-separate-files-webpack-loader/plugin')

module.exports = {
  chainWebpack: config => {
    config
      .plugin('vue-separate-files-webpack-loader')
      .use(VueSeparateFilesWebpackLoaderPlugin, [options])
      .after('vue-loader')

    config.module
      .rule('vue-separate-files-webpack-loader')
      .test(/\.vue\./)
      .use('vue-loader')
        .loader('vue-loader')
        .end()
      .use('vue-separate-files-webpack-loader')
        .loader('vue-separate-files-webpack-loader')
  }
}

Plugin options

Passed as regular Object.

Option	Default value	Description
test	/\.vue\./	When you use different file test condition in loader definition than default /\.vue\./, you have to define it also in plugin options.

Example

 // webpack.config.js

const VueSeparateLoaderPlugin = require('vue-separate-files-webpack-loader/plugin')

module.exports = {
  module: {
    rules: [
      {
        test: /\.condition\./,
        use: [
          {
            loader: 'vue-loader'
          },
          {
            loader: 'vue-separate-files-webpack-loader'
          }
        ]
      }
    ]
  },
  plugins: [
    new VueSeparateLoaderPlugin({
      test: /\.condition\./
    })
  ]
}

Supported file extensions / types

These file extensions are supported and automatically assigned to proper tag type by default.

• html, jade, pug
• js, jsx, coffee, ts, tsx
• css, sass, scss, styl, less

You can add support for other file extensions simply by adding following to loader configuration.

 types: {
  script: '\\.re$|\\.oj$' // add support for ".re" and ".oj" extensions for "script" type 
}

IMPORTANT! configurations are MERGED together, so there is no way do remove default configuration

How it works

Loader check files with .vue. within the name and creates actual .vue file structure on fly

Example

Taken this component structure

Component.vue.js
Component.vue.scoped.scss
Component.vue.pug

Generated structure

 <template src="Component.vue.pug" lang="pug"></template>
<style src="Component.vue.scss" lang="scss" scoped></style>
<script src="Component.vue.js"></script>

This generated string is then passed to vue-loader

Custom block support

Loader allows to use vue custom blocks.
Simply define file and its extension will be used as tag name.

Example

Component file

Component.vue.docs

Generated structure

 <docs src="Component.vue.docs"></docs>
