Building the Chat Server Core

Coming Soon

This lesson will integrate all the components you’ve built into a complete, working chat server. You’ll learn how to:

• Integrate WebSocket connections with chat rooms
• Implement message routing and delivery
• Build user session management
• Create room discovery and management
• Handle connection lifecycle events

What You’ll Build

By the end of this lesson, you’ll have implemented:

• A complete chat server with multiple rooms
• User session management with authentication
• Message routing and delivery systems
• Room creation and management
• A working real-time chat application

Key Concepts Preview

% Chat server architecture
-module(chat_server).
-behaviour(gen_server).

% Core functionality
handle_websocket_message(UserId, RoomId, Message) ->
    case chat_room_manager:send_message(RoomId, UserId, Message) of
        ok -> broadcast_to_room(RoomId, {message, UserId, Message});
        {error, Reason} -> send_error(UserId, Reason)
    end.

This lesson builds on the WebSocket protocol from Lesson 15 and prepares you for the message broadcasting patterns we’ll explore in Lesson 17.
