ng-observe

Installation

$ bower install ng-observe --save

Add this tags to you index.html file:

<script src="path-to-bower_components/angular/angular.js"></script>
<script src="path-to-bower_components/ng-observe/ng-obseve.js"></script>

And add this package as dependency to you main AngularJs module:

angular.module('YouModule', [... 'ngObserve']);

Now you can use Obseve factory in you AngularJs app.

Example

app.js

var app = angular.module('ExampleApp', ['ngObserve']);

app.factory('dataService', function(Observe) {
  var data = new Observe('test');
  return data;
});

app.controller('MainCtrl', function($scope, dataService) {
  $scope.message = '';
  $scope.onSubmit = function() {
    dataService.next($scope.message);
    $scope.message = '';
  };
});

app.controller('OtherCtrl', function($scope, dataService) {
  var sbscr = dataService.subscribe(function(data) {
    $scope.data = data;
  });
  $scope.$on('$destroy', function() {
    sbscr.cancel();
  });
});
