I'm building a chat system with Socket.IO and want to understand how the pieces fit together—not just copy code from a step-by-step tutorial. Are there any guides, books, or example projects that explain concepts like the connection handshake, events, rooms, and organizing a complete application?

Start with the official Socket.IO documentation. The getting-started guide is fairly readable and explains important concepts such as the connection handshake, events, namespaces, and rooms. After each section, try combining the examples into a small chat application so you can see how the individual pieces work together.
Look for a small, complete chat application built with Socket.IO and read it alongside the documentation. A good project should show the server setup, client connection, event handling, room management, and basic error handling. General programming Q&A sites can also help when you get stuck on a specific part, but it’s best to learn the core concepts from the official guide first.
I’m already working through the documentation and it explains the individual features well, but I’m still looking for a complete example that shows how to organize everything as one application.
