Elixir GenServer for State Management in Quiz Applications

Managing state in concurrent applications requires a solid understanding of process isolation and fault tolerance. This text-based course guides you through the foundational concepts of Elixir's OTP, focusing on how to build robust, isolated state containers for interactive applications. You will transition from basic process concepts to structured state management using GenServer. Learn to design clean interfaces, handle asynchronous events, and maintain data integrity across multiple concurrent sessions. What you will learn: Understand the core principles of Elixir processes and state isolation; Implement GenServer callbacks to initialize and update session state; Handle synchronous calls and asynchronous casts for quiz actions; Manage state transitions as users progress through questions; Apply modern Elixir patterns for error recovery and supervision. The course starts with fundamental concepts of stateful processes before moving into step-by-step implementation patterns for handling multi-user sessions. This course is designed for developers who have a basic understanding of Elixir syntax and want to learn real-world state management with OTP. Start building reliable, concurrent applications today.
