README

          
=== What's This?

Demo for the https://github.com/smallrye/smallrye-graphql[SmallRye GraphQL] extension library to add https://www.apollographql.com/docs/federation/federation-spec/[GraphQL Federation].

There's also an experiment for a Quarkus extension.

=== Howto Run The Demo

==== Backend Services: Java

The `film` and `review` services build a `war` that can run on a JEE server (tested with WildFly 23.0.1), either when the GraphQL feature pack is installed, or when built with the `fat` profile, so it includes the SmallRye GraphQL dependencies.

[NOTE]

The feature-pack currently contains a version of SmallRye GraphQL that has a bug that turns the `_Any` type into `_AnyInput`. So you'll have to use the `fat` deployment for now.

It contains the federation classes and a demo app delivering reviews for the films.

==== Gateway Service: Node

The federating `gateway` is a node service. Start it with the `start-gateway` commands defined in the `package.json`

==== Testing

Open the gateway playground at http://localhost:4000

An example query is:
