Learn How to Use the Inject Method in Angular 14

In Angular 14 we can use the inject() method which is a new way to apply Dependency Injection in our Angular applications.
We can use this method during the class creation or initialization and can be used as a class field, in the class constructor body, and in a factory method.

Good teacher! Easy to understand you deserve more subs!

Thank you master Profanis!)
The most valuable one thing to learn from this is that inheritance begins to seem a little more useful now)
Btw, inject() in a context of factory provider could be used for a pretty long time, I think when ivy got into a play or so

[hadirahmani]

How did you make the param name to show on vscode? Like in the logger token, it shows _desc as param name. Really helpful video. Thanks man

Hello . I would like to add that we can use the Inject method in any other hook or lifecycle, except from constructor utilizing the power of closures, as we are able to store the injected token inside the closure scope and still use values in the returned function. 😁😁😁|

exort const dispatchSearch = (): ((search: string) => void) => {
const store = inject(Store);
return (search) => store.dispatch(new SetSearch(search))
}

Hello.. thanks for your video...! why i am facing this issue? " NG0203: inject() must be called from an injection context"

[fahadgaliwango]

Thak you profanis .
Have understood it as way to reduce dependecies in the constructor, so they can be declared as global functions or variables, is that a correct take home

Pluck is being deprecated. You should update to use map operator

Thank you, very interesting, I think I need to repeat a lot of stuff about Class, to properly understand what is going on here ). Also what is a difference between take(1) and first()?

Well, that's a mess. inject() anywhere and everywhere. Peer Reviews, debugging and defect fixing are going to be more fun.
