Elixir Game State Management with GenServer and ETS

Building real-time multiplayer games requires a reliable way to manage fast-moving data without losing progress when things go wrong. Elixir provides powerful built-in tools to handle concurrent state and recover from failures instantly. This text-only course guides you through the core concepts of state management, helping you design robust game servers that keep player data safe, fast, and accessible under heavy load. What you'll learn: - Understand the fundamentals of state, processes, and the actor model in Elixir - Implement GenServer processes to manage individual game sessions and state transitions - Configure ETS (Erlang Term Storage) tables for ultra-fast, in-memory data retrieval - Design supervision trees to automatically recover game state after process crashes - Apply dynamic supervision strategies to scale game instances on demand - Integrate modern telemetry and structured logging to monitor state health and performance You will start with foundational definitions of Elixir processes and OTP behaviors before moving step-by-step into building a structured state storage system. Through clear written explanations and code examples, you will learn how to connect GenServers with ETS tables to create a production-ready persistence layer. This course is perfect for developers who understand basic Elixir syntax and want to transition into building reliable, stateful backend systems.
