    Library Documentation | Migrate from 2.0 to 3.0 | Migrating from jQuery guide

    Covers your javascript needs for those rainy days. A <3kb performant jQuery-like library born from the question: You might not need jQuery, then what do you need?

    You probably need awesome CSS (like Picnic CSS) and a lightweight, modern and performant javascript library. This does:

    • DOM traversal (selector, filter, find, each, etc.)
    • DOM editing (classes & attributes, html, before, etc.)
    • Event handling

    A couple of simple examples:

    // Simple events like jQuery
    u("button").on('click', e => {
      alert("Hello world");
    // Handle form submissions
    u('form.login').handle('submit', async e => {
      const user = await fetch('/login', {
        method: 'POST', body: new FormData(e.target)
      }).then(res => res.json());
      window.href = '/user/' + user.id;

    Getting started

    There are few ways to use Umbrella JS:

    Play with it

    Instead of installing it, you can just play with it in JSFiddle:

    Try on JSFiddle

    Use a CDN

    jsdelivr.com is an awesome OSS service that hosts many open source projects so you don't need to even download the code:

    <script src="https://cdn.jsdelivr.net/npm/umbrellajs"></script>

    Install with npm

    Using npm is a front-end package manager that makes it super-easy to add a new package:

    npm install umbrellajs

    Module support

    If you use a front-end module bundler like Webpack or Browserify, u is exposed as CommonJS exports. You can pull them in like so:

    // ES Modules/Webpack/etc
    import u from 'umbrellajs';
    // Commonjs
    var u = require('umbrellajs');

    ES Module support

    If you use an ES Module, u and ajax are exposed as ES Module exports. You can pull them in like so:

    import u from 'umbrellajs/umbrella.esm.js'

    Download it

    If you like it or prefer to try it locally, just download umbrella.min.js:

    Download Umbrella JS

    Add it to your project:

    <script src="umbrella.min.js"></script>

    Support: IE11+

    Current usage for IE 10- is under 1% for each version (8, 9, 10) so it's not Umbrella's mission to support this. However, those extra seconds gained from loading faster on mobile might be even bigger than that percentage. You should probably test it.
