Using the Angular Http Client in Angular v15
As part of the new standalone feature, Angular v15 introduces a new method to use the Http client API that doesn’t require using HttpClientModule:
As with the Router API, the new API exposes a provideHttpClient function that takes the features we want to use. Using interceptors is now made easier with a new feature function called withInterceptors(). It accepts a list of interceptor functions we want to use:
If you still want to use the current interceptors without changing your code, you can provide the withInterceptorsFromDi() feature:
Interceptors in Lazy Loaded Modules
The ability to define interceptors in lazy-loaded modules has been requested for a long time. A new developer preview feature in this version of Angular makes this possible to do it. We can use the withRequestsMadeViaParent() feature in our lazy loaded routes and modules:
In the above case, each request initiated by the TodoComponent and its children will use both the inline and the global interceptors 🙌 (inline runs first)
