bacon.js bindings for AngularJS.

Make your AngularJS apps even more reactive, by using bacon.js FRP library to process your scope properties.

Simply require angular-bacon in your AngularJS module, and both $rootScope and Bacon objects are augmented automatically with the following functions:

$scope.$watchAsProperty(property)

Exposes an AngularJS scope property as a bacon.js property. If the property already has a value in the scope (i.e. is not undefined), that value becomes the property's initial value.

$scope.$watchCollectionAsProperty(property)

Exposes an AngularJS scope Array or Object property as a bacon.js property. If the property already has a value in the scope (i.e. is not undefined), that value becomes the property's initial value.

This function is equivalent to $scope.$watchAsProperty but using $watchCollection instead of $watch, so that changes in Array and Object values are properly detected.

Bacon.Observable.digest($scope, property)

Digests a bacon.js observable (stream or property) back to an AngularJS scope property. Attaches an .onValue handler to the observable, which simply $applies the property in the selected scope with the selected key.

$scope.digestObservables(observables)

Digests multiple bacon.js observables at once. Simple syntactic sugar, when multiple observables are involved. observables is a map with object keys representing $scope property names into which the observables are digested into.

$scope.$asEventStream(event)

Subscribes to scope hierarchy events as Bacon.EventStream. event is a name of the event. Created stream will contain AngularJS scope event objects, augmented with an .args property, containing a list of all additional arguments passed in the $emit call.

For examples, see here. This example somewhat mimics raimohanska's awesome bacon.js tutorials: it features a simple login validation form, where a slow backend "is-nickname-taken" check is simulated by a stream with a 5-second delay. In addition, the two selected passwords must match, and be at least five characters long before the submit button is enabled.
