Building a Quiz Manager with Elixir GenServer Processes

Modern concurrent applications require robust state management and fault tolerance. This text-based course guides you through building a structured Quiz Manager in Elixir, leveraging the power of OTP and processes to handle state isolation and data validation seamlessly. You will start with the absolute fundamentals of Elixir processes before moving into real-world application architectures. By completing this course, you will understand how to design, implement, and supervise stateful processes that keep your application resilient even when unexpected errors occur. What you'll learn: - Understand the core principles of Elixir processes and the Actor model - Implement stateful GenServer processes to manage quiz data and user sessions - Configure supervision trees to isolate errors and ensure high availability - Apply data validation patterns to secure state transitions within your application - Learn modern testing techniques for asynchronous and concurrent Elixir code This course begins with foundational concepts, defining how processes communicate and store state, before guiding you step-by-step through the implementation of a fully functioning quiz management backend. It is designed for developers who are new to OTP and want a clear, practical introduction to building resilient systems. No prior experience with GenServer or OTP is required, though a basic familiarity with Elixir syntax will help you get the most out of the material.
