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
