A production Socket.IO server should be configured according to application requirements.

Important configuration options include:

• maxHttpBufferSize: Maximum incoming message size.
• pingInterval: Interval between server ping packets.
• pingTimeout: Time allowed for the client to respond.
• connectTimeout: Time allowed for a client to establish a namespace connection.
• transports: Available transport mechanisms.

These values influence connection behavior and resource usage.

Do not arbitrarily increase message size or timeout values. Choose settings based on actual payload requirements, network conditions, and infrastructure limits.

const io = new Server(httpServer, {
  maxHttpBufferSize: 1e6,
  pingInterval: 25000,
  pingTimeout: 20000,
  connectTimeout: 45000
});
