bun.Serve.Options

type Options<WebSocketData, R extends string = string> = Bun.__internal.XOR<HostnamePortServeOptions<WebSocketData>, UnixServeOptions<WebSocketData>> & Bun.__internal.XOR<FetchOrRoutes<WebSocketData, R>, FetchOrRoutesWithWebSocket<WebSocketData, R>>

Options for serve, with support for routes and a safer requirement for fetch

export default {
  fetch: req => Response.json(req.url),

  websocket: {
    message(ws) {
      ws.data.name; // string
    },
  },
} satisfies Bun.Serve.Options<{ name: string }>;
