Mixing Laravel Mix with Vapor

Trying a different framework after using Laravel is anything but easy. And as I was expecting, it didn’t take me too long to realize this. Laravel is not only a solid, well-written, and well-documented framework but it also brings with it a handful of essential packages such as Cashier, Socialite, Echo, Dusk etc. These packages are officially supported and make your day to day job as a web developer much enjoyable and very productive.

The first thing I missed right away using Vapor was the lack of a good front end build tool for compiling assets such as JavaScripts and CSS. I’m sure there exists one but I didn’t find any “officially promoted” one and nothing as good as Laravel Elixir, or it’s next version - Laravel Mix.

Yes, I know there are many build tools such as Gulp, Webpack, Grunt, Rollup etc. But, for better or worse, Laravel has spoiled me. I want to be more productive writing actual code and not spent hours fiddling with configurations.

Thankfully, Laravel Mix, despite its name, seems to work well with any other kind of frameworks including Vapor. There are few Laravel specific features such as the need for a function called mix if you need versioning but nothing that should block us from using it in our own Vapor project. In this post, I’ll show you how to integrate Laravel Mix in your own Vapor project. …

Initializing project and adding dependencies

1: Create a new Vapor project:

$ vapor new Hello

2: cd into Hello directory and initialize npm to create a new package.json file:

$ cd Hello && npm init -y

3: Let’s install laravel-mix package:

$ npm install laravel-mix --save-dev

Adding assets for compiling

We are now ready to compile our assets but first we need some assets. For this article, let’s create one .js file and one .scss file:

1: Create app.js under Resources/Assets/js folder:

$ mkdir -p Resources/Assets/js && touch Resources/Assets/js/app.js

2: Open app.js file and add this:

console.log('Mixing Laravel Mix with Vapor')

3: Create app.scss under Resources/Assets/scss folder:

$ mkdir -p Resources/Assets/scss && touch Resources/Assets/scss/app.scss

4: Open app.scss file and add this:

body {
background: red;

Adding a mix file and Webpack commands

You need a webpack.mix.js file in the project’s root folder. webpack.mix.js is like a master control for your assets. This is where you mix and remix your JavaScript files, CSS styles, copy fonts etc. Read Laravel Mix documentation to learn more about this file.

1: Create a new file webpack.mix.js under project’s root folder, open it and add the following:

let mix = require('laravel-mix').mix
mix.js('Resources/Assets/js/app.js', 'Public/js')
.sass('Resources/Assets/scss/app.scss', 'Public/css')

Here, we are saying that we want to compile Resources/Assets/js/app.js to Public/js/app.js file and Resources/Assets/scss/app.scss to Public/css/app.css file.

Now, we need to add some triggers to actually run compilation using this file.

2: Open package.json file and add/ modify scripts object to include these npm scripts:

"scripts": {
"webpack": "cross-env NODE_ENV=development webpack --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"dev": "cross-env NODE_ENV=development webpack --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"production": "cross-env NODE_ENV=production webpack --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"

3: Now from the command line run:

$ npm run webpack

If everything goes well, you should see a Compiled successfully message.


You should have two new files under your Public folder: Public/js/app.js and Public/css/app.css (Don’t worry about manifest.json file for now). You can add these assets to your view files the way you would include any other .js or .css files.

If you want your assets to be compiled every time you make changes to one of your assets file, run this command:

$ npm run dev

When you are ready to publish your web app, you want your assets to be minified. In such case, you want to run:

$ npm run production
