Using the Sass indented syntax with Vueify and VueJS 2

Among many CSS preprocessors available these days, SASS is definitely my favorite, especially because of its indented syntax (.sass files).

These days I’m rewriting a web app using VueJS 2, using the Browserify template generated by the VueJS CLI. Since this framework is almost entirely based on components, the author provided a way to write a component in one file, which is split into three portions: template, logic and style. These can be written in a single .vue file which contains a template tag, a script tag and a style tag:

  <h1>Hello, World!</h1>

  export default {
    name: "HeaderComponent"

  h1 {
    color: #bada55

It’s important to note that the Vue ecosystem includes a Browserify plugin (transform) that handles these .vue files and it’s called Vueify, which is installed with the other NPM packages when a project is bootstrapped using the official Vue CLI using the Browserify template.

Now, in the style portion of your .vue file, you can write SASS just by adding a lang attribute to the tag:

<style lang="sass">
    color: #bada55

However, in order for this to work, we have to make a couple of changes to our projects. Assuming you have the SASS Ruby Gen installed on your system, we first need to install the node-sass package:

npm install --save-dev node-sass

The next step is to create a file named vue.config.js at the root of our project directory (if it’s not there already), with the following code:

module.exports = {
  sass: {
    includePaths: ['./src/sass'],
    indentedSyntax: true

Note the indentedSyntax property set to true. This tells Vueify that our sass syntax is, obviously, the indented one. Of course if we set it to false, or just don’t set it at all, Vueify will compile SASS written in its normal syntax (the one using braces and semicolons).

Don’t hesitate to contact me if you have questions.
