# angular-promise-extras
[](https://circleci.com/gh/ohjames/angular-promise-extras)
## Installation
1. Install the package
```
bower install --save angular-promise-extras
```
2. Add the bower source file to your web page.
3. Add the angular module `ngPromiseExtras` as a dependency of your application module.
## Usage
```javascript
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:
```javascript
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 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`.
