PostCSS Import Fontawesome Fix

laravel tip laravel-mix gotchas

So I recently created a new Laravel application based on the Jetstream starter template; which I highly recommend by the way if you just want to focus on your application logic and not have to reinvent the authentication proverbial wheel.

I knew I wanted to use Fontawesome for all my icons (Hero and Feather icons are also great alternatives) but I was having an issue getting it to import into my project with laravel-mix throwing the following error.

Unknown error from PostCSS plugin. Your current PostCSS version is 8.2.10, but postcss-import uses 7.0.35. Perhaps this is the source of the error below.
ERROR in ./resources/css/app.css
Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):
ModuleBuildError: Module build failed (from ./node_modules/postcss-loader/dist/cjs.js):
Error: Failed to find '~@fortawesome/fontawesome-pro/css/all.min.css'

After reading forum posts about changing versions of PostCSS/Import and trying the Tailwind PostCSS 7 compatibility build it still wasn't working.

I re-read the Fontawesome documentation again (after just skimming it through the first time) and I noticed they were referencing the JS versions of their scripts over CSS.

  <!-- Our project just needs Font Awesome solid + brand -->
  <script defer src="/your-path-to-fontawesome/js/brands.js"></script>
  <script defer src="/your-path-to-fontawesome/js/solid.js"></script>
  <script defer src="/your-path-to-fontawesome/js/fontawesome.js"></script>
  <i class="fas fa-user"></i> <!-- uses solid style -->
  <i class="fab fa-github-square"></i> <!-- uses brand style -->

So I tried just importing the Fontawesome JS in the resources/js/app.js instead of the CSS in resources/js/app.css and the error disappeared.

Below is the working app.js.

// js/app.js
import './bootstrap';

import 'alpinejs';

// Import through JS and not CSS.
import '@fortawesome/fontawesome-pro/js/all.min';
