propagate

Propagate events from one event emitter into another.

Install

$ npm install propagate

Propagate

var ee1 = new EventEmitter()
var ee2 = new EventEmitter()
propagate(ee1, ee2)
 
ee2.on('event', function(a, b) {
  console.log('got propagated event', a, b)
})
 
ee1.emit('event', 'a', 'b')

Unpropagate

You can unpropagate by ending the propagation like this:

var ee1 = new EventEmitter()
var ee2 = new EventEmitter()
var p = propagate(ee1, ee2)
 
// ...
 
p.end()

Only propagate certain events:

var ee1 = new EventEmitter()
var ee2 = new EventEmitter()
var p = propagate(['event1', 'event2'], ee1, ee2)

Propagate certain events as other events:

var ee1 = new EventEmitter()
var ee2 = new EventEmitter()
var p = propagate(
  {
    event1: 'other-event1',
    event2: 'other-event2',
  },
  ee1,
  ee2
)
