JarCastingAngular bluebird promises
This is a drop in replacement for $q that makes the bluebird API compatible with angulars subset of $q then simply swaps it out.
With this module you can use all of bluebirds additional promise methods on the $q service, the full list can be found here:
http://bluebirdjs.com/docs/api-reference.html
Installation
The library depends on angularJS and Bluebird.
It is recommended that you install the library and its dependencies through bower:
bower install --save angular-bluebird-promises
You will then need to include the JS files for the plugin:
<script src="bower_components/bluebird/js/browser/bluebird.js"></script>
<script src="bower_components/angular/angular.min.js"></script>
<script src="bower_components/angular-bluebird-promises/dist/angular-bluebird-promises.min.js">
And finally add the module dependency in your AngularJS app:
angular.module('myApp', ['mwl.bluebird']);
Alternatively you can install through npm:
npm install --save angular-bluebird-promises
Then add as a dependency to your app:
angular.module('myApp', [require('angular-bluebird-promises')]);
Usage
Simply use $q as you normally would. It will function exactly as before, however you will now have bluebirds additional API methods available as well on all promises throughout your angular app.
$q.all vs. bluebird Promise.all
The behavior of the $q.all(...) function is actually a combination of bluebird's Promise.props and Promise.all function depending on whether an object or an array is passed, respectively. This behavior is preserved such that calling $q.all with an object will pass through to Promise.props while calling it with an array will pass through to Promise.all.
Unhandled rejections
By default the value of onPossiblyUnhandledRejection is set to angular.noop. You can and should override this with your own handler in order to catch uncaught errors. For example:
angular.module('mwl.bluebird').run(function($q, $log) {
$q.onPossiblyUnhandledRejection(function(err) {
$log.warn('Unhandled rejection', err);
});
});
If using the ui-router this will produce some noise. To get around this you can do something like:
$q.onPossiblyUnhandledRejection(function(exception) {
if (exception.message.match(/transition (superseded|prevented|aborted|failed)/)) {
return;
}
// Handle exception
});
Example
angular.module('mwl.example', ['mwl.bluebird']).run(function($q, $http) {
var promises = [
$http.get('test/angular.json'),
$http.get('test/bluebird.json')
];
//Note the use of spread which isn't available normally on $q
$q.all(promises).spread(function(angular, bluebird) {
console.info('\\m/ It worked! \\m/', angular.data.name, bluebird.data.name);
}).catch(console.error);
});
