`@socket.io/component-emitter`

Event emitter component.

This project is a fork of the component-emitter project, with Socket.IO-specific TypeScript typings.

Installation

$ npm i @socket.io/component-emitter

API

Emitter(obj)

The Emitter may also be used as a mixin. For example a "plain" object may become an emitter, or you may extend an existing prototype.

As an Emitter instance:

1import { Emitter } from '@socket.io/component-emitter';
2
3var emitter = new Emitter;
4emitter.emit('something');

As a mixin:

1import { Emitter } from '@socket.io/component-emitter';
2
3var user = { name: 'tobi' };
4Emitter(user);
5
6user.emit('im a user');

As a prototype mixin:

1import { Emitter } from '@socket.io/component-emitter';
2
3Emitter(User.prototype);

Emitter#on(event, fn)

Register an event handler fn.

Emitter#once(event, fn)

Register a single-shot event handler fn, removed immediately after it is invoked the first time.

Emitter#off(event, fn)

Pass event and fn to remove a listener.
Pass event to remove all listeners on that event.
Pass nothing to remove all listeners on all events.

Emitter#emit(event, ...)

Emit an event with variable option args.

Emitter#listeners(event)

Return an array of callbacks, or an empty array.

Emitter#hasListeners(event)

Check if this emitter has event handlers.
