EE First
Get the first event in a set of event emitters and event pairs, then clean up after itself.
Install
$ npm install ee-first
API
var first = require('ee-first')
first(arr, listener)
Invoke listener on the first event from the list specified in arr. arr is
an array of arrays, with each array in the format [ee, ...event]. listener
will be called only once, the first time any of the given events are emitted. If
error is one of the listened events, then if that fires first, the listener
will be given the err argument.
The listener is invoked as listener(err, ee, event, args), where err is the
first argument emitted from an error event, if applicable; ee is the event
emitter that fired; event is the string event name that fired; and args is an
array of the arguments that were emitted on the event.
var ee1 = new EventEmitter()
var ee2 = new EventEmitter()
first([
[ee1, 'close', 'end', 'error'],
[ee2, 'error']
], function (err, ee, event, args) {
// listener invoked
})
.cancel()
The group of listeners can be cancelled before being invoked and have all the event listeners removed from the underlying event emitters.
var thunk = first([
[ee1, 'close', 'end', 'error'],
[ee2, 'error']
], function (err, ee, event, args) {
// listener invoked
})
// cancel and clean up
thunk.cancel()
