Improve this AngularJS factory to use with socket.io

Question

I want to use socket.io in AngularJS. I found the following factory:

app.factory(\'socket\', function ($rootScope) {
    var socket = io.connect();
    retur         


        

Answer 1

I use something like the code below. socketsService is only instantiated once and I believe Angular takes care of GC the $on's

If you don't like $broadcast/$on, there are some slightly more solid Message Bus implementations for Angular available...

app.service('socketsService', ['$rootScope', function ($rootScope) {
    var socket = window.io.connect();

    socket.on('info', function(data) {
        $rootScope.$broadcast("info_received", data);
    });

    socket.emit('ready', "Hello");
}]);

app.controller("infoController",['$scope',
    function ($scope) {
        $scope.$root.$on("info_received", function(e,data){
            console.log(data);
        });
        //...
    }]);

app.run(
    ['socketsService',
        function (socketsService) {
        //...
    }]);
