Usage
var deferreds = [ $q.defer(), $q.defer() ]
var asyncVals = deferreds.map(function(deferred) {
return deferred.promise
})
asyncVals.push(3)
$q.allSettled(asyncVals).then(function(values) {
expect(values).toEqual([
{ state: 'fulfilled', value: 1 },
{ state: 'rejected', reason: 2 },
{ state: 'fulfilled', value: 3 },
])
})
deferreds[0].resolve(1)
deferreds[1].reject(2)
Also works with objects:
var deferreds = [ $q.defer(), $q.defer() ]
var promisesArray = deferreds.map(function(deferred) {
return deferred.promise
})
var promises = { a: promisesArray[0], b: promisesArray[1], c: 3 }
$q.allSettled(promises).then(function(values) {
expect(values).toEqual({
a: { state: 'fulfilled', value: 1 },
b: { state: 'rejected', reason: 2 },
c: { state: 'fulfilled', value: 3 },
})
})
deferreds[0].resolve(1)
deferreds[1].reject(2)
Also provides
$q.map: works likeBluebird.maporBluebird.propsdepending on whether an array or an object is passed.$q.mapSettled: Works like$q.mapbut with the settled semantics.$q.resolve: Works likeBluebird.resolve.
