rx-angular - npm

This library serves as a bridge between the Reactive Extensions for JavaScript (RxJS) and AngularJS.

With this library, you will be able to do such things as easily watch values as they change, as observable sequences such as:

angular.module('example', ['rx'])
  .controller('AppCtrl', function($scope, observeOnScope) {
 
    
    observeOnScope($scope, 'name').subscribe(function(change) {
      $scope.observedChange = change;
      $scope.newValue = change.newValue;
      $scope.oldValue = change.oldValue;
    });
  });

And with your HTML markup you can use it like this:

<div class="container" ng-app="example" ng-controller="AppCtrl">
  <h2>Reactive Angular</h2>
  <ul class="list-unstyled">
    <li>observedChange {{observedChange}}</li>
    <li>newValue: {{newValue}}</li>
    <li>oldValue: {{oldValue}}</li>
  </ul>  
 
  <input type="text" ng-model="name" />
</div>

Another example is where we can create an Observable sequence from such things ng-click expressions where we can search Wikipedia:

angular.module('example', ['rx'])
  .controller('AppCtrl', function($scope, $http, rx) {
 
    function searchWikipedia (term) {
      return rx.Observable
        .fromPromise($http({
          url: "http://en.wikipedia.org/w/api.php?&callback=JSON_CALLBACK",
          method: "jsonp",
          params: {
            action: "opensearch",
            search: term,
            format: "json"
          }
        }))
        .map(function(response){ return response.data[1]; });             
    }
 
    $scope.search = '';
    $scope.results = [];
 
    
    $scope.$createObservableFunction('click')
      .map(function () { return $scope.search; })
      .flatMapLatest(searchWikipedia)
      .subscribe(function(results) {
        $scope.results = results;
      });
  });

And the HTML markup you can simply just use a ng-click directive much as you have before, but now it is an Observable sequence.

<div class="container" ng-app="example" ng-controller="AppCtrl">
 
  <input type="text" ng-model="search">
  <button ng-click="click()">Search</button>
 
  <ul>
    <li ng-repeat="result in results">{{result}}</li>
  </ul>
 
</div>

This only scratches the surface of what is possible when you combine the two libraries together.
