Socket.IO Namespaces: Channels on One Connection
Socket.IO namespaces are virtual channels over a single WebSocket connection, letting you split app logic without multiple connections. Use them for separate areas like `/admin` or for multi-tenancy.
Think of Socket.IO namespaces as virtual channels multiplexed over one WebSocket connection, letting you split logic for `/users` vs. `/orders` without extra network overhead. They're perfect for creating distinct areas with their own authentication and event handlers, like a private `/admin` section or a separate workspace for each tenant in a SaaS app. The main footgun is accidentally disabling multiplexing; creating multiple client sockets or using `forceNew: true` will create new connections, defeating the purpose.
