vue-compile

Compile the blocks in Vue single-file components to JS/CSS from Babel/Sass/Stylus.

Why This Approach

We want to publish .vue files instead of transformed .js files on npm because the .vue file is preferred in some scenarioes, e.g. vue-server-renderer can inline critical CSS from <style> blocks.

This tool will transform each block in the .vue file to their standard conterparts like sass -> css so your users don't have to install additional libraries to compile it.

Install

yarn global add vue-compile
# or
npm i -g vue-compile

Usage

# normalize a .vue file
vue-compile example.vue -o output.vue
# normalize a directory
# non .vue files will be simply copied to output directory
vue-compile src -o lib

Then you can publish normalized .vue files to npm registry without compiling them to .js files.

Supported transforms (via lang attribute):

  • <template> tag:
    • html (default)
  • <script> tag:
    • babel (default): use our default babel preset or your own .babelrc
    • ts typescript: use our default babel preset + @babel/preset-typescript
  • <style> tag:
    • postcss (default): use your own postcss.config.js
    • stylus sass scss
  • Custom blocks: They are not touched.

Gotchas:

  • We only handle src attribute for <style> blocks, we simply replace the extension with .css and remove the lang attribute.
Example

In:

<template>
  <div class="foo">
    {{ count }}
  </div>
</template>

<script>
export default {
  data() {
    return {
      count: 0
    }
  }
}
</script>

<style lang="scss" src="./foo.scss">

<style lang="stylus" scoped>
@import './colors.styl'

.foo 
  color: $color
</style>

Out:

<template>  
  <div class="foo">
    {{ count }}
  </div>
</template>

<script>
export default {
  data: function data() {
    return {
      count: 0
    };
  }
};
</script>

<style src="./foo.css">

<style scoped>
.foo {
  color: #f00;
}
</style>

Compile Standalone CSS Files

CSS files like .css .scss .sass .styl will be compiled to output directory with .css extension, all relevant import statements in .js .ts or <script> blocks will be changed to use .css extension as well.

You can exclude them using the --exclude "**/*.{css,scss,sass,styl}" flag.
