Worker Entrypoint

The Worker entrypoint usually exports:

• a default fetch handler
• each Durable Object class as a named export

Worker.make(...) supplies the Worker-side runtime for ordinary HTTP handling. ActorNamespace provides the Worker-side Durable Object binding, while ActorRuntime.make(...) defines the Durable Object class.

Build the entrypoint

 
export { TicTacToeRuntime as TicTacToe }
 
const layerApi = Layer.mergeAll(
  HttpRouter.add("GET", "/", Effect.succeed(HttpServerResponse.text("ok"))),
  HttpRouter.add(
    "GET",
    "/play",
    Effect.gen(function* () {
      const { gameId, player } = yield* GameState.init
      return yield* TicTacToeNamespace.bind(gameId).upgrade({ player })
    }),
  ),
  HttpRouter.cors({
    allowedHeaders: ["*"],
    allowedMethods: ["*"],
    allowedOrigins: ["*"],
  }),
  HttpRouter.add("*", "/*", Assets.forward),
)
 
export default Worker.make({
  handler: layerApi.pipe(HttpRouter.toHttpEffect, Effect.flatten),
  prelude: Layer.mergeAll(
    layerKv,
    TicTacToeNamespace.layer,
    Assets.layer("ASSETS"),
  ),
})

Things to notice

• HttpRouter.add(method, path, effect) mounts a single route.
• HttpRouter.cors(...) wires up CORS for every route in the router.
• HttpRouter.add("*", "/*", Assets.forward) falls through to the Cloudflare Assets binding for unmatched requests.
• Worker.make({ handler, prelude }) produces the Worker fetch export.
• The Durable Object runtime class must be re-exported from the Worker entrypoint under the binding's class name.
