Cash

Cash is an absurdly small jQuery alternative for modern browsers (IE10+) that provides jQuery-style syntax for manipulating the DOM. Utilizing modern browser features to minimize the codebase, developers can use the familiar chainable methods at a fraction of the file size. 100% feature parity with jQuery isn't a goal, but Cash comes helpfully close, covering most day to day use cases.

Usage

Get Cash from CloudFlare or jsDelivr and use it like this:

<script src="https://cdnjs.cloudflare.com/ajax/libs/cash/4.1.5/cash.min.js"></script>
<script>
  $(function () {
    $('html').addClass ( 'dom-loaded' );
    $('<footer>Appended with Cash</footer>').appendTo ( document.body );
  });
</script>

Cash is also available through npm as the cash-dom package:

npm install cash-dom --save-dev

That you can then use like this:

import $ from "cash-dom";

$(function () {
  $('html').addClass ( 'dom-loaded' );
  $('<footer>Appended with Cash</footer>').appendTo ( document.body );
});

Documentation

Cash gives you a query selector, collection methods and some library methods. If you need more details about our API just check out jQuery's, while we don't implement everything that jQuery provides, everything what we do implement should be compatible with jQuery. Cash can be extended with custom methods, read how here.

$()

This is the main selector method for Cash. It returns an actionable collection of nodes.

If a function is provided, the function will be run once the DOM is ready.

$( selector [, element] ) // => collection, using `element` as the context
$( selector [, collection] ) // => collection, using `collection` as the context
$(node) // => collection
$(nodeList) // => collection
$(htmlString) // => collection
$(collection) // => self
$(function () {}) // => document ready callback

Collection Methods

These methods from the collection prototype ($.fn) are available once you create a collection with $() and are called like so:

$(element).addClass ( className ) // => collection

Some extra methods are available but disabled by default.
