#Angular dependency injection in depth – View Providers (2021, Advanced)

Dependency Injection is a huge and advanced topic in #angular and if you have been following my channel you should know pretty much everything about it. However, there is one remaining thing to cover - View Providers. I would not say it is widely used feature but it is definitely worth to figure out what gives us View Providers and when it could be useful. Please leave your feedbacks in comments and let's get started to explore further Angular DI. Enjoy!

Men soo good the explanation!!!. I basically an ng pro now :)

[igorparampam]

Спасибо, наконец то смог разобраться.

[alexeykharchenko]

I can't understand the usefull case for that.
Why we can't just simply use required service (GalleryCustomLoggerService) inside GallerySlideComponent (inject in constructor)?

[giorgikirvalidze]

skipself would do exactly same thing as view providers does right ?

[krzysztoftokarz]

Hello Dmytro! First of all, your content is great and your explainations are very clear. However i tried to check it in Angular 15 and standalone components and it looks like the bevahior is different. Could you please check this out? Is this some kind of bug with standalone components?

[navnathjadhav]

In short does it means view providers is not available for projected content? They are only limited to current component or current component children?

[ilirbeqiri]

Great Content! But what would happen if the slides' components are declared inside the gallery component's template. Will the service will be available also to them?

[Yumo]

Pretty cool!! but what if i want to user different services instances on the app-gallery-slide component. Thanks for theses videos theyre super usefull

[waldBestMusics]

How can you use the new service in the gallery and in the slide ?, now only is used in the slide component ?

[ihor-pidhornyi]

What if we remove providers from the component where we are using gallery with gallery slides. Does "viewProviders" make providing own service optional? So what I mean, it's like es6 default argument value, if we not provide this argument, default value will be used in the function

[JavierAcrich]

So, can we conclude that if you have an ng-content in the template, you should use viewProviders ?

Couldn't spot the difference it made. Can anyone help?
