GraphQL — forge/server has it built in

const { WebApp, GraphQLEngine } =
  require(class="tk-str">'@hyperbridge/forge/server');

const app = new WebApp();

const gql = new GraphQLEngine({
  typeDefs: class="tk-str">`
    type Query {
      hello: String
      user(id: Int!): User
    }
    type User { id: Int, name: String }
  `,
  resolvers: {
    Query: {
      hello: () => class="tk-str">'world',
      user:  (_, { id }) => ({ id, name: class="tk-str">`User ${id}` }),
    },
  },
});

app.post(class="tk-str">'/graphql', async (c) => {
  const { query, variables } = await c.req.json();
  return c.json(await gql.execute(query, variables));
});

app.listen(3000);
