A bitwise powered event emitter :-)

Bee - Bitwise Event Emitter

Bee is a JavaScript event emitter which support topics as bitmasks and OFFC (of fucking course) it also works like a charm with normal topics such as string ones; as you already do and probably don't knew.

Well, what?

Nothing. Probably your code hurts 'cause you always spend more keystrokes when you want to listen to both events and have the same callback for them. Don't understand what I mean? Great, let's zoom it:

var myAwesomeCallback = function() {
    // some sort of voodoo happens here.
    // ...
};

target.on('event:a', myAwesomeCallback);
target.on('event:b', myAwesomeCallback);

Hell yeah. .

We already overcome those kind of stuff, let's go ahead playing with simple bitwise operations such as:

var EVENT_A = 1; // 1 << 0
var EVENT_B = 2; // 1 << 1

target.on(
    EVENT_A | EVENT_B,
    myAwesomeCallback
);

IHA! We're on the way, much better, nein?

Why? when?

I'm drunk, can't explain now.

That's why GitHub exists, bro. Then, you can, always and all ways. And also we'll bid you a beer if your PR change my life.

bee.js's Issues

Add tests and integration with Travis

Move from 6to5 to babel

Alias for `.on`, addEventListener

Also for .off too, removeEventListener?

Create a standard event object

This event object should be passed as first argument for the callbacks.

It must have:

• .source the object which emitted the event
• .name the topic used to emit the event
• .stopImmediatePropagation to break the emit loop
