EventEmitter based on EventTarget

evem

evem is a simple EventTarget based event emitter. The following methods are available on the emitter:

• on - attach a listener
• off - remove a listener
• once - attach a listener to listen only once
• emit - dispatch an event with optional custom payload

The original emitter instance is exported as well for those just in case scenarios. The only reason this package exists is so that code duplication may be prevented. Otherwise, I end up recreating these in every other library project.

Usage

Use it simply as:

import evem from 'evem'

function handler(e) {
    console.log('received an event with payload: ', e);
}

evem.on('my-custom-event', handler);
evem.emit('my-custom-event'); // this prints the console message
