I enjoy your videos but the text editor you use drives me crazy :p

[@MonsterlessonsAcademy]

Sorry about that :)

[@knowa130]

@@MonsterlessonsAcademy I mean I also highly appreciate your skill with that. I can see you're super proficient with this way of coding :)

​@@MonsterlessonsAcademy how do you replace the below code using the new injet() method? @Inject(SOME_TOKEN) private _service: Service

NOW i get this! thanks!

[@MonsterlessonsAcademy]

Great!

[@stickyamp5996]

Finally i understand what is "provide"

[@MonsterlessonsAcademy]

Glad to hear that!

[@sivakumartadisetti3885]

Thanks for the explanation. But what is the advantage of injecting the constant instead of just export and importing the constant into the component files? Just curious to know

[@MonsterlessonsAcademy]

We use injection token to register things in angular. you can't just use constant there.

[@MonsterlessonsAcademy]

Thanks!

Another great video! Thanks. How do Injection Tokens work with services in a stand alone environment with no NgModules?

[@MonsterlessonsAcademy]

The same way. You just register it in component and not in module.

[@MultiWarrr]

If you may make a video about ngrx entities related data normalization

[@MonsterlessonsAcademy]

Thanks for the idea. I will add it to the list.

[@MaheshKumar-bg5re]

Please make a video for ssr auth

[@MonsterlessonsAcademy]

I will add it to the list of ideas for future videos.

[@anmolsingh4969]

nice

[@MonsterlessonsAcademy]

thanks

[@slowmoshotsPZ]

can you please provide me the use case when to use it?

[@MonsterlessonsAcademy]

It happens automatically for you every time when you register service. Injection token allow you to write custom code of using/defining services for your needs. I you don't see use cases for your project you might not have any.

[@user-oh4cn7ub2m]

Can you explain why do we need string to be provided in InjectionToken, it is just description, in your case, you left it blank, so why we need it at all? can we use this string or it is just description

[@MonsterlessonsAcademy]

It is just a description not a value

[@user-oh4cn7ub2m]

@@MonsterlessonsAcademy so why do we need it. And thanks for making the best video on Token i have seen, very informative
