vueify

Browserify transform for Vue.js components, with scoped CSS and component hot-reloading.

This transform allows you to write your components in this format:

// app.vue
<style>
  .red {
    color: #f00;
  }
</style>

<template>
  <h1 class="red">{{msg}}</h1>
</template>

<script>
  module.exports = {
    data: function () {
      return {
        msg: 'Hello world!'
      }
    }
  }
</script>

You can also mix preprocessor languages in the component file:

// app.vue
<style lang="stylus">
.red
  color #f00
</style>

<template lang="jade">
h1(class="red") {{msg}}
</template>

<script lang="coffee">
module.exports =
  data: ->
    msg: 'Hello world!'
</script>

And you can import using the src attribute:

<style lang="stylus" src="style.styl"></style>

Under the hood, the transform will:

extract the styles, compile them and insert them with the insert-css module.
extract the template, compile it and add it to your exported options.

You can require() other stuff in the <script> as usual. ~~Note that for CSS-preprocessor @imports, the path should be relative to your project root directory.~~ Starting in 7.0.0, @import in LESS, SASS and Stylus files can be either relative to your build tool root working directory, or to the file being edited.

Usage

npm install vueify --save-dev
browserify -t vueify -e src/main.js -o build/build.js

If you are using npm 3+, it no longer auto install the peer dependencies. So you will also have to do:

npm install\
  vueify-insert-css vue-hot-reload-api\
  babel-core babel-preset-es2015\
  babel-plugin-transform-runtime babel-runtime@5\
  --save-dev

And this is all you need to do in your main entry file:

// main.js
var Vue = require('vue')
var App = require('./app.vue')

new Vue({
  el: 'body',
  components: {
    app: App
  }
})

In your HTML:

<body>
  <app></app>
  <script src="build.js"></script>
</body>

If you are using vueify in Node:

var fs = require("fs")
var browserify = require('browserify')
var vueify = require('vueify')

browserify('./entry.js')
  .transform(vueify)
  .bundle()
  .pipe(fs.createWriteStream("bundle.js"))

ES2015 by Default

Vueify automatically transforms the JavaScript in your *.vue components using Babel. Write ES2015 today!

The default Babel (6) options used for Vue.js components are:

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

If you wish to override this, you can add a .babelrc file at the root of your project:

{
  "presets": ["es2015", "stage-2"],
  "plugins": ["transform-runtime"]
}

You can also configure babel with the babel field in vue.config.js, which will take the highest priority.

Enabling Pre-Processors

You need to install the corresponding node modules to enable the compilation. e.g. to get stylus compiled in your Vue components, do npm install stylus --save-dev.

These are the built-in preprocessors:

stylus
less
scss (via node-sass)
jade
coffee-script

Autoprefix by Default

Starting in 5.0.0, all CSS output via vueify will be autoprefixed by default. See config section below on customizing the options.

PostCSS

Vueify uses PostCSS for scoped CSS rewrite and autoprefixing. You can also provide your own PostCSS plugins! See config section below for an example.

Configuring Options

Create a vue.config.js file at where your build command is run (usually the root level of your project):

module.exports = {
  // configure a built-in compiler
  sass: {
    includePaths: [...]
  },
  // provide your own postcss plugins
  postcss: [...],
  // configure autoprefixer
  autoprefixer: {
    browsers: ['last 2 versions']
  },
  // register custom compilers
  customCompilers: {
    // for tags with lang="ts"
    ts: function (content, cb) {
      // compile some TypeScript...
      cb(null, result)
    }
  }
}

Example using custom PostCSS plugin:

var cssnext = require('cssnext')

module.exports = {
  postcss: [cssnext()],
  // disable autoprefixer since cssnext comes with it
  autoprefixer: false
}

Alternatively, if you are using vueify in Node and don't want to create a vue.config.js file:

var fs = require("fs")
var browserify = require('browserify')
var vueify = require('vueify')

// apply custom config
vueify.compiler.applyConfig({
  // ...same as in vue.config.js
})

browserify('./entry.js')
  .transform(vueify)
  .bundle()
  .pipe(fs.createWriteStream("bundle.js"))

Scoped CSS

Experimental

When a <style> tag has the scoped attribute, its CSS will apply to elements of the current component only. This is similar to the style encapsulation found in Shadow DOM, but doesn't require any polyfills. It is achieved by transforming the following:

<style scoped>
.example {
  color: red;
}
</style>
<template>
  <div class="example">hi</div>
</template>

Into the following:

<style>
.example[_v-1] {
  color: red;
}
</style>
<template>
  <div class="example" _v-1>hi</div>
</template>

Notes

You can include both scoped and non-scoped styles in the same component.
A child component's root node will be affected by both the parent's scoped CSS and the child's scoped CSS.
Partials are not affected by scoped styles.

Hot Reload

Experimental

To enable hot component reloading, you need to install the browserify-hmr plugin:

npm install browserify-hmr --save-dev
watchify -p browserify-hmr index.js -o bundle.js

A full setup example with hot reloading is available at vuejs/vueify-example.

Compiler API

The compiler API (originally vue-component-compiler) is also exposed:

var compiler = require('vueify').compiler

// filePath should be an absolute path
compiler.compile(fileContent, filePath, function (err, result) {
  // result is a common js module string
})

Syntax Highlighting

Currently there are syntax highlighting support for Sublime Text, Atom, Vim and Visual Studio Code. Contributions for other editors/IDEs are highly appreciated! If you are not using any pre-processors in Vue components, you can also get by by treating *.vue files as HTML in your editor.

Example

For an example setup using most of the features mentioned above, see vuejs/vueify-example.

If you use Webpack, there's also vue-loader that does the same thing.

Changelog

8.1.0

Vueify now respects .babelrc over default options.

8.0.0

babel-core is now a peer dependency.

7.0.0

Added relative @import path support and import dependency tracking for LESS, SASS & Stylus. Now you can @import files using relative paths to the file being edited, and editing these imported files will also trigger watchify rebuild.
Removed built-in compiler for myth. Prefer using PostCSS + CSSNext.

6.0.0

Upgraded to Babel 6. This is a breaking change because the babel configuration is now different.

5.0.4

Added postcss option for providing custom PostCSS plugins.

5.0.0

New: CSS output is now autoprefixed by default.
Changed: New config file format

4.0.0

Support ES2015 by default.

3.0.0

Added support for scoped CSS and component hot reloading.

2.0.1

Built-in lang for ES2015 has been renamed from es6 to es.
es transforms now uses loose mode and optional runtime by default. This means in addition to installing babel, you should also install babel-runtime.
Templates and CSS are now non-minified by default. To enable minification, run the build with NODE_ENV=production.
Options for built-in pre-processors can now be configured in vue.config.js.
vue-component-compiler has been merged into vueify. It is now exposed as require('vueify').compiler.
