Less Preprocessing

Basic Usage

Here's a quick example to get you started. Imagine that you have the following Less file that needs to be compiled to vanilla CSS.

// src/app.less
@primary: grey;

.app {
    background: @primary;

No problem. Let's add Less compilation to our webpack.mix.js file.

// webpack.mix.js
let mix = require('laravel-mix');

mix.less('src/app.less', 'dist');

Compile this down as usual (npx mix), and you'll find a /dist/app.css file that contains:

.app {
    background: grey;


Plugin Options

Behind the scenes, Laravel Mix of course defers to webpack's less-loader to load and compile your Less files. From time to time, you may need to override the default options that we pass to it. Use the third argument to mix.less() in these scenarios.

mix.less('src/app.less', 'dist', {
    lessOptions: {
        strictMath: true

For a full list of supported options, please refer to the webpack documentation for less-loader.

Multiple Outputs

Should you need to compile more than one root file, you may call mix.less() as many as times as necessary. For each call, webpack will output a new file with the relevant contents.

mix.less('src/app.less', 'dist/') // creates 'dist/app.css'
    .less('src/forum.less', 'dist/'); // creates 'dist/forum.css'
