This is a fork of tiny-emitter with generic type support for events!

typed-tiny-emitter

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

Install

npm

npm install typed-tiny-emitter --save

Usage

1var Emitter = require('typed-tiny-emitter');
2var emitter = new Emitter();
3
4emitter.on('some-event', function (arg1, arg2, arg3) {
5 //
6});
7
8emitter.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.

1var emitter = require('typed-tiny-emitter/instance');
2
3emitter.on('some-event', function (arg1, arg2, arg3) {
4 //
5});
6
7emitter.emit('some-event', 'arg1 value', 'arg2 value', 'arg3 value');
