[TomChv]

What are you trying to do?

Expose the GraphQL client directory from the dag variable

See https://discord.com/channels/707636530424053791/1230428619755753553

Why is this important to you?

Allow greater flexibility and special use case like calling other module

How are you currently working around this?

Current workaround from this discord message

connect(
  async (client: Client) => {
    await client
      .moduleSource("github.com/shykes/daggerverse/hello")
      .asModule()
      .initialize()
      .serve();
    const res = await (
      await client["_ctx"].connection()
    ).request(gql`
      query {
        hello {
          hello
        }
      }
    `);
    console.log(res);
  },
  { LogOutput: process.stderr },
);
