How to use apollo-link-batch-http with Angular?

[digeomel]

Hi,

we have been using Apollo with Angular 8 for a long time now, using the apollo-angular-link-http module. I thought I'd give the batch http link a try, but it seems it's not exactly a one-to-one replacement for the http-link, as I thought.

Specifically, I tried to replace:

    const apiLink = httpLink.create({
        uri: AppConfig.graphqlEndPoint
    });

with:

    const apiLink = new BatchHttpLink({
        uri: AppConfig.graphqlEndPoint
    });

and I'm getting the error:

NullInjectorError: StaticInjectorError(AppModule)[GraphQLModule -> BatchHttpLink]: 
  StaticInjectorError(Platform: core)[GraphQLModule -> BatchHttpLink]: 
    NullInjectorError: No provider for BatchHttpLink!

Am I missing something?
Thank you in advance.
