bling.js

Because you want the $ of jQuery without the jQuery.

---

You may be interested in bling.js if you get tired of the [].slice.call( document.querySelectorAll('.foo'), function(){ … rodeo. It does this:

// forEach over the qSA result, directly.
document.querySelectorAll('input').forEach(el => /* ... */);

// on() rather than addEventListener()
document.body.on('dblclick', evt => /* ... */);

// classic $ + on()
$('p').on('click', el => /* ... */);

It doesn't do anything else. This is not a jQuery equivalent.

Notes:

• on() works on elements, document, window, and results from querySelector & querySelectorAll.
• $ is qSA so if you're grabbing a single element you'll have to [0] it.
• Bling plays well with authoring ES6
• Resig explored this stuff a while ago: github.com/jeresig/nodelist
• Bling doesn't work on Android 2.3 or iOS 5.0. Works everywhere else including IE8 (assuming Function.bind)

Nerdy implementation notes:

• The NodeList prototype usually inherits from Object, so we move it to Array.
• I'm curious how ES6/7 would let a NodeList be iterable and inherit from EventTarget
• Setting Node.prototype.on = EventTarget.prototype.addEventListener is awesome. It works in Chrome/FF but not yet in IE/Safari.
• I haven't set up any off() or trigger() to map to dispatchEvent & removeEventListener. I'm OK with that.
• I'm using semi-standard for style. I tried standard sans-semicolons, but can't get used to it.

bling.js

/* bling.js */

window.$ = document.querySelectorAll.bind(document);

Node.prototype.on = window.on = function (name, fn) {
  this.addEventListener(name, fn);
}

NodeList.prototype.__proto__ = Array.prototype;

NodeList.prototype.on = NodeList.prototype.addEventListener = function (name, fn) {
  this.forEach(function (elem, i) {
    elem.on(name, fn);
  });
}
