Event Dispatcher

The simplest ever event dispatcher in 117 bytes (minified).

Motivation

In the search for reducing the size of the JS bundle, I started looking at all the things that could be compressed/simplified in an MVC framework. And that's when I realized that we don't need to implement a new events system because all web browsers already have it built-in.

This library's only objective is to provide a simpler interface to trigger and listen for events on client-side Javascript.

Usage

You can listen for events this way:

on('myCustomEvent', function(evt) {
    console.log('An event of type "myCustomEvent" was triggered');
});

And you can also trigger them:

emit('myCustomEvent');

In case you are thinking: can I send data along with the event? The answer is yes, very simply:

emit('user:created', { name: 'John' });

And you can find the data object under the detail property of the event.

on('user:created', function(user) {
    console.log('User created:', user.name);
});
