ontime-eventemitter v1.0.0

The class is used to implement pattern Mediator. The common idea of the class has been taken from NodeJS native class EventEmitter and class BackboneJS Events.

npm install ontime-eventemitter

import { EvenEmitter } from 'ontime-eventemitter';

const emitter: EvenEmitter = new EvenEmitter();

// create callback function
const cb = (name: string): void => console.log('Hello', name);

// subscribe callback
emitter.on('say', cb);

// send event
emitter.emit('say', 'John'); // -> Hello John
emitter.emit('say', 'Helen'); // -> Hello Helen

// unsubscribe callback
emitter.off('say', cb);

on(name: name, callback: Function) - Subscribe callback. The callback will be invoked whenever the event is fired.

once(name: name, callback: Function) - Just like "on", but causes the callback to fire only once before being removed.

off(name: name, callback: Function) - Unsubscribe previously callback.

emit(name: name, ...args) - Emit callbacks for the given event. Subsequent arguments to trigger will be passed along to the event callbacks.

stopListening() - Remove all listeners.
