README for tiny-emitter

tiny-emitter

A tiny (less than 1k) event emitter library.

Install

npm

npm install tiny-emitter --save

Usage

var Emitter = require('tiny-emitter');
var emitter = new Emitter();

emitter.on('some-event', function (arg1, arg2, arg3) {
 //
});

emitter.emit('some-event', 'arg1 value', 'arg2 value', 'arg3 value');

Alternatively, you can skip the initialization step by requiring tiny-emitter/instance instead. This pulls in an already initialized emitter.

var emitter = require('tiny-emitter/instance');

emitter.on('some-event', function (arg1, arg2, arg3) {
 //
});

emitter.emit('some-event', 'arg1 value', 'arg2 value', 'arg3 value');

Instance Methods

on(event, callback[, context])

Subscribe to an event

  • event - the name of the event to subscribe to
  • callback - the function to call when event is emitted
  • context - (OPTIONAL) - the context to bind the event callback to

once(event, callback[, context])

Subscribe to an event only once

  • event - the name of the event to subscribe to
  • callback - the function to call when event is emitted
  • context - (OPTIONAL) - the context to bind the event callback to

off(event[, callback])

Unsubscribe from an event or all events. If no callback is provided, it unsubscribes you from all events.

  • event - the name of the event to unsubscribe from
