XMPP: AngularJs + Strophe.js

Question

I have a basic XMPP client working on strophe.js.

On login I create handlers such as

connect = new Strophe.Connection('http://localhost/http-bind');
...
...

    connect.addHandler(on_message, null, "message", "chat");
    connect.addHandler(on_presence, null, "presence");

...
...

and then I "listen" to those

function on_presence(presence) {
// handling presence
}

function on_message(presence) {
// handling presence
}

So I am trying to "convert" it into AngularJS. The first part is pretty straight forward. I have a controller which handles the login part just fine:

angular.module('app').controller('loginCtrl', function($scope) {
connect = new Strophe.Connection('http://website.com/http-bind');

connect.connect(data.jid, data.password, function (status) {
  if (status === Strophe.Status.CONNECTED) {
    connect.addHandler(on_message, null, "message", "chat");
    connect.addHandler(on_presence, null, "presence");
  }
}
})

But how do I actually begin listening to those events (on_message, on_presence) in the context of angular across all the controllers I have.

Answer 1

Wrap Strophe in an Angular Service. Angular Services are meant to be use as singletons, so you will be able to instantiate the Strophe Service once, and use it everywhere (using Dependency Injection).

Answer 2

As suggested above (or bellow) I wrapped strophe in a service so my login "mechanism" looks like this:

.controller('loginCtrl', function(xmppAuth) {

    xmppAuth.auth(login, password);

})

any my service:

.service('xmppAuth', function() {

return {

auth: function(login, password) {
   connect = new Strophe.Connection('http://mydomain.net/http-bind');
   connect.connect(login, password, function (status) {
       if (status === Strophe.Status.CONNECTED) {
           // we are in, addHandlers and stuff
       }
   }
}

}

})
