Can not access globalThis.__io

[duytnb79]

When I access globalThis.__io, it always return undefined. How can I fix it ? Thank you for supporting.

Additional, I use environment io.to(roomId).emit('function') to send message to specific room in socket. I think we need to guide to use it.

Sorry for not clearly, I mean I want to use globalThis.__io in development environment. But I see this code in file server.ts

export function createIOHandler<T extends Record<string, (io: SocketServer) => void>> (functions: T, serverOptions: Partial<ServerOptions>) {
  return eventHandler((event) => {
    if (!globalThis.__io && process.env.NODE_ENV === 'production') {
      const httpServer = (event.node.req.socket as any).server as Server
      const io = new SocketServer(httpServer, serverOptions)

      Object.keys(functions).forEach((fn) => {
        functions[fn](io)
      })

      globalThis.__io = io
    }
  })
}

Can you point me how to use it.

I found this aswell. I have no clue why its only set to run this code while in production and not in development

Is it possible to access the socket from middlewares so that it can be attached to the context?

You would have to set your .env.NODE_ENV = 'production'

However. Nitro seems to have issues with websockets, it doesnt allow new connections after 6 clients has connected even if some of them disconnect. I would recommend following this thread as it seems like Nitro is working on websockets support. https://github.com/unjs/nitro/issues/678
