I am trying to connect socket.io with my angular application. I have come across some examples of creating a service that can be accessed by the controller, and I understand that part. However, I am looking for a solution where all controllers can respond to event calls from socket.io.
For example:
socket.on('user joined', function (data) {});
I know how to do this in one controller, but I need a way to implement it for all controllers. How can I achieve this?
To optimize your socket usage in Angular controllers, you should create a service to encapsulate the socket and inject it as necessary.
Here is how you can create a socket service:
app.factory('socket', function ($rootScope) {
var socket = io.connect();
return {
on: function (eventName, callback) {
socket.on(eventName, function () {
var args = arguments;
$rootScope.$apply(function () {
callback.apply(socket, args);
});
});
},
emit: function (eventName, data, callback) {
socket.emit(eventName, data, function () {
var args = arguments;
$rootScope.$apply(function () {
if (callback) {
callback.apply(socket, args);
}
});
})
}
};
});
Next, we will inject this service into a controller and utilize it using the socket.io API:
function AppCtrl($scope, socket) {
socket.on('init', function (data) {
$scope.name = data.name;
$scope.users = data.users;
});
}
You have the flexibility to customize the controller based on your requirements with the socket service.
