Structuring Elixir Applications with OTP and GenServers

Writing clean, maintainable Elixir code requires more than just understanding syntax; it demands a solid grasp of how to structure your applications around OTP. Many developers struggle with mixing business logic directly into GenServer callbacks, leading to codebases that are difficult to test and maintain. This text-only course provides a clear, step-by-step guide to separating your core domain logic from OTP process machinery, ensuring your Elixir projects remain clean and modular. What you'll learn: * Understand foundational OTP terminology, processes, and state management principles * Separate pure domain logic from GenServer callback functions for better testability * Implement synchronous call and asynchronous cast patterns effectively * Configure robust supervision trees to manage process lifecycles and fault tolerance * Structure Elixir applications using modern design patterns and clean architecture * Practice writing testable OTP code using modern testing strategies You will begin by mastering essential terminology and basic process concepts before diving into practical refactoring techniques and structural patterns. This course is designed for Elixir developers who are new to OTP or looking to improve their application design skills, with no prior OTP experience required. Start reading today to build cleaner, more resilient Elixir systems.
