TL;DR
1) When you’re using a Factory you create an object, add properties to it, then return that same object. When you pass this factory into your controller, those properties on the object will now be available in that controller through your factory.
app.controller(‘myFactoryCtrl’, function($scope, myFactory){
$scope.artist = myFactory.getArtist();
});
app.factory(‘myFactory’, function(){
var _artist = ‘Shakira’;
var service = {};
service.getArtist = function(){
return _artist;
}
return service;
});
2) When you’re using Service, AngularJS instantiates it behind the scenes with the ‘new’ keyword. Because of that, you’ll add properties to ‘this’ and the service will return ‘this’. When you pass the service into your controller, those properties on ‘this’ will now be available on that controller through your service.
app.controller(‘myServiceCtrl’, function($scope, myService){
$scope.artist = myService.getArtist();
});
app.service(‘myService’, function(){
var _artist = ‘Nelly’;
this.getArtist = function(){
return _artist;
}
});
3) Providers are the only service you can pass into your .config() function. Use a provider when you want to provide module-wide configuration for your service object before making it available.
app.controller(‘myProvider’, function($scope, myProvider){
$scope.artist = myProvider.getArtist();
$scope.data.thingFromConfig = myProvider.thingOnConfig;
});
app.provider(‘myProvider’, function(){
//Only the next two lines are available in the app.config()
this._artist = ‘’;
this.thingFromConfig = ‘’;
this.$get = function(){
var that = this;
return {
getArtist: function(){
return that._artist;
},
thingOnConfig: that.thingFromConfig
}
}
});
app.config(function(myProviderProvider){
myProviderProvider.thingFromConfig = ‘This was set in config’;
});
Non TL;DR
1) Factory
Factories are the most popular way to create and configure a service. There’s really not much more than what the TL;DR said. You just create an object, add properties to it, then return that same object. Then when you pass the factory into your controller, those properties on the object will now be available in that controller through your factory. A more extensive example is below.
