The Decisions Behind It.
What made this hard?
In real-time messaging, message ordering, delivery guarantees, and reconnection handling are the part nobody sees in a demo and the part that breaks everything in production.
How was the system structured?
The Socket.io event layer is kept separate from the REST layer: persistent data over REST, live events over sockets. A room-based channel model lets group conversations scale horizontally, and message persistence is decoupled from socket delivery so an offline user's message is never lost.
What does the codebase look like now?
Socket events follow a naming convention and a central event registry, which keeps client and server contracts in sync. Reconnection and retry logic is isolated on the client, so network-failure behaviour is controlled from one place.
