Is it possible to inject a service into apollo-client's middleware? There is Apollo module. https://www.npmjs.com/package/apollo-angular At the documentation there is an advice how to implement authentication. The communication is done using localStorage. http://dev.apollodata.com/angular2/auth.html It is not Angular2 way. I need confirmation. I've been for solution for some time.

I would use one of two options:
Option 1:
- Have an Auth service that manages login/tokens etc.
- Inject the Auth service into the service where you construct Apollo.
- Inside the middleware that adds your token, retrieve the token from the injected Auth service.
Option 2:
Have the service that constructs your Apollo client also manage Auth state. Inject it into the page where you log in to handle authentication and store the token after.
I know it's very old, but just in case, the injection is made into deps:
providers: [
{
provide: APOLLO_NAMED_OPTIONS,
deps: [HttpLink, AuthService],
useFactory: createApollo,
},
],
then you just add a parameter into your createApollo(httpLink: HttpLink, authService: AuthService) factory function.
