A small library that adds a number of utility methods to Angular's $q promises.
Simply add ngPromseDsl as a dependency in your module definition
angular.module('myAwesomeApp', ['ngPromiseDsl'])
Sets the value the promise resolves to onto the given object under the given property name.
promise.thenSet($scope, 'myValue');
Alternatively, sets a constant value when the promise resolves:
promise.thenSet($scope, 'showSpinner', false);
Sets all keys from a $q.all() call to the given object under those same keys. Do note that this
will wait for all promises to resolve before setting them, which may appear slower than setting
the values individually
$q.all([myPromise, myOtherPromise])
.thenSetAll($scope);
Alias for .catch(), so it can be used with ES 3 (IE 8)
promise.except(function(error) { $log.error(error); });
Similar to .thenSet(), only for error cases
promise.exceptSet($scope, 'showError', true);
Picks a given property from the resolved value and passes it to the next callback in the promise chain
promise
.thenTake('subValue')
.thenSet($scope, 'value');
Returns a fixed value on success or failure; useful for converting promises that contain business logic (resolves when successful, rejects when failed) to booleans that can be put on the scope
promise
.thenReturn(true, false)
.thenSet($scope, 'wasSuccessful')
Calls the given method with the promise value when it resolves, returning the original value. Useful for chaining and not having to declare an explicit return for the callback
promise.thenExec(calculateTotals);
Calls the given method (by name) on the object the promise resolves to. Useful in combination with Restangular
promise.thenApply('get', 'sub-resource');
Redirects the user to the given path on success using $location, optionally replacing the url.
promise.thenRedirectTo('/success');
promise.thenRedirectTo('/success', true); // calls $location.replace()
- Publish on npm repositories
- Write installation instructions once there
thenLog(logLevel)method that calls $log with the promise result or a constant value
