bling dot js


Because you want the $ of jQuery without the jQuery.

You may be interested in bling.js if you get tired of the [] 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.


  • 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:
  • 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 */
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);

Is this safe to use in production?

@Ollie-w yeah totally.

I think I have an interesting fork:

  • only mutates the nodes queried with the exported function
  • offers 'off'
  • offers nice attribute CRUD operations

@AdaRoseCannon has a nice extension of this idea which maps ALL things in the Element prototype onto the NodeList prototype

A (proxied) Nodelist with all Apis of Elements (also future).
