# Cash
Cash is an absurdly small jQuery alternative for modern browsers (IE11+) 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.
## Comparison
| Size | Cash | Zepto 1.2.0 | jQuery Slim 3.4.1 |
| ------------------ | ----------- | ----------- | ----------------- |
| Unminified | **34.9 KB** | 58.7 KB | 227 KB |
| Minified | **15.3 KB** | 26 KB | 71 KB |
| Minified & Gzipped | **5.7 KB** | 9.8 KB | 24.4 KB |
A **76.6%** gain in size reduction compared to jQuery. If you need a smaller bundle, we support [partial builds](https://github.com/fabiospampinato/cash/blob/master/docs/partial_builds.md) too.

If you're migrating from jQuery be sure to read our [migration guide](https://github.com/fabiospampinato/cash/blob/master/docs/migration_guide.md).
## Usage
Get Cash from [CloudFlare](https://cdnjs.cloudflare.com/ajax/libs/cash/7.0.3/cash.min.js) or [jsDelivr](https://cdn.jsdelivr.net/npm/cash-dom@7.0.3/dist/cash.min.js) and use it like this:
```html
<script src="https://cdnjs.cloudflare.com/ajax/libs/cash/7.0.3/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](http://npmjs.com) as the [`cash-dom`](https://www.npmjs.com/package/cash-dom) package:
```sh
npm install --save cash-dom
```
That you can then use like this:
```js
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](#collection-methods) and some [library methods](#cash-methods). If you need more details about our API just check out [jQuery's](http://api.jquery.com), 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](https://github.com/fabiospampinato/cash/blob/master/docs/extending_cash.md).
### $()
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.
```js
$( 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](#fn)) are available once you create a collection with `$()` and are called like so:
```js
$(element).addClass ( className ) // => collection
```
Some [extra methods](https://github.com/fabiospampinato/cash/tree/master/src/extra) are available but [disabled](https://github.com/fabiospampinato/cash/blob/master/pacco.json#L3) by default.
