Using Laravel Mix Without Laravel

APRIL 5, 2018

Laravel ships with the laravel-mix npm module installed. Laravel Mix is a wrapper around Webpack that simplifies the process of compiling your web assets (which seems to be useful for "80% of the use cases").

Still, if all you want is to use it for compiling your assets (say, compile your SCSS or SASS or Less styles to minified CSS, or compile and minify your JavaScript assets) it is not a trivial process to follow. I hope this notes help remove any problems you might find to get going.

Setting Up Your Project

Let's assume we are starting from scratch; a new empty folder. We'll want to initialize our npm directory as follows.

npm init

You can accept all the defaults of the npm init command. This will create a package.json in your directory.

Install Laravel Mix

Next, we need to install the following node packages: laravel-mix, webpack, and cross-env.

npm install laravel-mix cross-env

You can expect this command to take several minutes to install and compile all of the required dependencies. (It will also install webpack as it is a dependency of laravel-mix.)

Create Your webpack.mix.js File

Now, create the webpack.mix.js file, which serves as a configuration to specify via laravel-mix what you want webpack to do. Places this contents inside it:

let mix = require('laravel-mix');

mix.sass('assets/style.scss', 'dist')
   .js('assets/app.js', 'dist');

This will compile your SCSS assets (style.scss) to CSS (style.css) and place it inside the dist folder, and compile your JavaScript assets (app.js) also into the dist folder (app.js). (Make sure that you do place those files style.scs and app.js inside the assets folder (or specify what files you'd like to compile.

Add npm Commands to Your package.json

The only piece we are missing is a command to tell Webpack to process our operations. Place this command inside the "scripts" dictionary of your package.json file (that should have been created when you ran the npm init command.

"scripts": {
	"dev": "npm run development",
	"development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
	"watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
	"watch-poll": "npm run watch -- --watch-poll",
	"hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
	"prod": "npm run production",
	"production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},

Compile Your Assets

Now you can compile your assets for development (no minifying but faster).

npm run development

Or for production (slower but minified and less file size).

npm run production

Note that you can use npm run dev and npm run prod as shorthands instead of npm run development and npm run production.


You can also run the watch command while you are editing your assets during development — Laravel Mix will re-compile everything you make changes to one of your asset files and save. This will make your development experience even better. Just remember to compile in production before deploying your application so your assets get minified.

npm run watch

You are all set!
