Angular Poller

Build Status devDependency Status

Lightweight AngularJS poller service which can be easily injected into controllers. It uses a timer and sends requests every few seconds to keep the client synced with the server. If you need the data to be exact real-time such as in a chat box, you should use long polling or WebSocket instead.

Error Handling

One way to capture error responses is to use the catchError option. It indicates whether poller should get notified of error responses. ```javascript var myPoller = poller.get(myResource, { catchError: true });

myPoller.promise.then(null, null, function (result) {

}); ```

Alternatively you can use AngularJS interceptors for global error handling like so: javascript angular.module('myApp', ['emguo.poller']) .config(function ($httpProvider) { $httpProvider.interceptors.push(function ($q, poller) { return { 'responseError': function (rejection) { if (rejection.status === 503) { // Stop poller or provide visual feedback to the user etc poller.stopAll(); } return $q.reject(rejection); } }; }); });

Multiple Resources

Multiple Controllers

In order to automatically stop all pollers on navigating between views with multiple controllers, you can use pollerConfig. ```javascript var myModule = angular.module('myApp', ['emguo.poller']);

myModule.config(function (pollerConfig) { pollerConfig.stopOnStateChange = true; // If you use $stateProvider from ui-router. pollerConfig.stopOnRouteChange = true; // If you use $routeProvider from ngRoute. }); ```
