Apollo Angular HTTP Link

apollo-angular-link-http is an Apollo Link implementation designed for Angular applications to facilitate sending GraphQL operations over standard HTTP requests. This package leverages Angular's `HttpClient` (`@angular/common/http`) for network communication. While its last stable version, `1.11.0`, was released over three years ago, its core functionality for creating an HTTP link has largely been integrated and superseded by the primary `apollo-angular` package. As such, `apollo-angular-link-http` is now considered abandoned. Modern Angular and Apollo setups typically configure `HttpLink` directly through `apollo-angular`'s `ApolloClient` creation process, often utilizing `provideApollo()` for dependency injection. This package previously served as a distinct module for HTTP-based GraphQL communication before the `apollo-angular` ecosystem evolved to incorporate this functionality directly.
