Hello everyone, good night,
I wanted to know two things the first is when I should use the factory directive and the other is if for example inside a factory I can make an Ajax request and return the result of it in a method of my factory, someone would have a example of this?
Using factory is one of the ways to create services with Angularjs. In addition to factory, you can use service and provider. All three variants have significant differences ( link ), however they all create a singleton service in your angularjs application.
Yes, it is possible and very common to encapsulate ajax calls within a service, see the example below:
app.factory('myService', function ($http) {
var getData = function () {
return $http.get("api/getdata/");
};
return getData; // note que factory deve ter um retorno
});
