Simplify an Angular Service using a JavaScript Object as a Value Provider
Often it might be simply easier to create the implementation out of a simple JavaScript object rather than a full blown class. That’s where value providers come in play!
Instructor: [00:00] Often, rather than defining an entire class here for our service in Angular, it might be much simpler to simply provide a predefined JavaScript object. What we can do is, as the definition where we basically define our service, we can actually create here something like a simple logger. Which is nothing else than a JavaScript object.
[00:21] It obviously has to match the API of our logger, which we will override. We can now go here below and define that in a different kind of way. We say whenever you see something like the logger service, then use a value.
[00:43] We use the simple logger here. If you click here now on our component, you can see that our simple logger JavaScript object is being picked up, rather than a full-blown ECMAScript class.
[00:58] This one here can be moved out to dedicated file, it shouldn't be defined inline here in that app module.
