Real-Time Elixir: Integrating LiveView with OTP GenServer

Modern web development often requires complex frontend frameworks to achieve real-time interactivity, but Elixir offers a powerful and unified alternative. By combining the real-time rendering of Phoenix LiveView with the robust state management of OTP GenServers, you can build seamless, concurrent applications with minimal friction. This text-based course guides you through the foundational concepts of stateful Elixir development, helping you transition from static pages to dynamic, real-time interfaces. You will understand how to manage state across multiple users, handle background processes, and orchestrate communication between your web interface and the Erlang VM. What you'll learn: Understand the core architecture of Phoenix LiveView and how it maintains persistent socket connections; Configure OTP GenServers to manage state, handle asynchronous tasks, and run background processes; Integrate LiveView processes with GenServer state to push real-time updates directly to the user interface; Apply PubSub patterns to broadcast events across multiple connected user sessions; Implement testing strategies for LiveView and GenServer interactions to ensure application reliability. The course starts with essential definitions and foundational concepts of the Actor model and OTP. You will then progress through step-by-step written explanations and clear code examples, moving from basic state management to a fully integrated, multi-user system. This course is designed for developers who have a basic familiarity with Elixir syntax and want to learn how to build real-time web applications. No advanced OTP or LiveView experience is required.
