How to use uWebSocketsTransport with colyseus

[chiragpetals]

Hey @endel, I am currently working on a project that uses colyseus, i came across this documentation for using uwebsocketsjs for production environments (https://docs.colyseus.io/server/transport/uwebsockets#uwebsocketsjs), but i am unable to find a way to use it with my existing colyseus code,

• How can i use express with this ?
• How can i define room types?

I also noted one issue, when i passed the config object to new Server(config), the transport field became undefined

Sample Code

const config = {
  gracefullyShutdown: true,
  transport: new uWebSocketsTransport({
    maxPayloadLength: 4096,
  }),
};

console.log("transport -", config.transport); // exists
const gameServer = new Server(config);
console.log("transport -", config.transport); // undefined

gameServer.define('GameRoom', RoomInstance, {});

Hi @chiragpetals, since Colyseus 0.16 the uWebSocketsTransport() comes with uwebsockets-express compatibility layer built-in (see source-code).

You can access the express instance via:

const app = config.transport['expressApp'];

Beware that express v5 is not supported by the compatibility layer yet. I'm working to make the uwebsockets-express layer compatible with express v5 at this exact moment (work in progress is on express-v5 branch).
