Nano Events

Simple and tiny event emitter library for JavaScript.

Only 108 bytes (minified and brotlied). It uses Size Limit to control size.
The on method returns unbind function. You don’t need to save callback to variable for removeListener.
TypeScript and ES modules support.
No aliases, just emit and on methods. No Node.js EventEmitter compatibility.

import { createNanoEvents } from 'nanoevents'

const emitter = createNanoEvents()

const unbind = emitter.on('tick', volume => {
  summary += volume
})

emitter.emit('tick', 2)
summary //=> 2

unbind()
emitter.emit('tick', 2)
summary //=> 2
