const Greeter = createToken<{ hello(): string }>("Greeter");

const greet = defineModule({
  name: "greet",
  providers: [
    {
      token: Greeter,
      useValue: { hello: () => "hi" },
    },
  ],
  async setup(ctx) {
    ctx.logger.info(ctx.container.resolve(Greeter).hello());

const app = createApp({ modules: [greet] });
await app.boot();
await app.dispose();
