AssetMapper

Build a cutting-edge frontend by leveraging modern web standards like ECMAScript modules (ESM), importmaps & preloading, with zero building or complex Node setup.

1. Install JavaScript packages in your application: 

$ composer require symfony/asset-mapper
$ php bin/console importmap:require js-confetti

2. Start using them immediately: 

// assets/app.js
import JSConfetti from 'js-confetti';

const jsConfetti = new JSConfetti();
jsConfetti.addConfetti();

That's all. No build required.
Refresh and it works!
