on-first experimental

Attach an EventEmitter listener that emits before all other existing listeners for that event.

Note: it's also worth checking out timoxley's overshadow-listeners. The API offers more flexibility, and unlike on-first only uses the public EventEmitter API.

Usage

on-first

require('on-first')(emitter, event, listener)

  • emitter is the EventEmitter to listen to.
  • event is the event to listen to.
  • listener is the event callback.
