angular-promise-extras-extended v0.2.3

angular-promise-extras-extended

This is a fork of angular-promise-extras in order to improve semantic with isFulfilled and isRejected

Installation

WebPack

1. Install the package

   npm install --save angular-promise-extras-extended

2. require/import angular-promise-extras.

3. Add the angular module ngPromiseExtras as a dependency of your application module.

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, isFulfilled: true, isRejected: false },
    { state: 'rejected', reason: 2, isFulfilled: false, isRejected: true },
    { state: 'fulfilled', value: 3, isFulfilled: true, isRejected: false },
  ])
})

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, isFulfilled: true, isRejected: false },
    b: { state: 'rejected', reason: 2, isFulfilled: false, isRejected: true },
    c: { state: 'fulfilled', value: 3, isFulfilled: true, isRejected: false },
  })
})

deferreds[0].resolve(1)
deferreds[1].reject(2)

Also provides

• $q.map: works like Bluebird.map or Bluebird.props depending on whether an array or an object is passed.
• $q.mapSettled: Works like $q.map but with the settled semantics.
• $q.resolve: Works like Bluebird.resolve.
