Long polling service in AngularJS

README.md

Then in your controller, inject $polling and start polling like this.

General use

$polling.startPolling({name_of_this_polling}, {url_to_fetch_data_from}, {time_in_milli_seconds}, {callback});

Example,

$polling.startPolling('fetchNotifications', 'http://localserver.local/fetch/notifications', 10000, $scope.processData);

To stop a polling

$polling.stopPolling('fetchNotifications');
