const server = new ApolloServer({
  typeDefs: [KeycloakTypeDefs, typeDefs], // 1. Add the Keycloak Type Defs
  schemaDirectives: KeycloakSchemaDirectives, // 2. Add the KeycloakSchemaDirectives
  resolvers,
  context: ({ req }) => {
    return {
      kauth: new KeycloakContext({ req }) // 3. add the KeycloakContext to `kauth`
    }
  }
})

server.applyMiddleware({ app })

app.listen({ 4000 }, () =>
  console.log(`🚀 Server ready at http://localhost:4000${server.graphqlPath}`)
