Connecting Phoenix Web Interfaces to Elixir Business Logic

Modern web applications require a seamless connection between what the user sees on the screen and the complex business logic running on the server. Developers often struggle to bridge the gap between interactive web interfaces and stateful backend systems. This text-based course guides you step-by-step through the process of connecting a Phoenix web interface with Elixir-driven application logic, using a stateful game engine as a practical model. You will start with core web-to-backend communication concepts, explore how to manage state, and learn how to handle user inputs cleanly. What you will learn: Understand the foundational principles of stateful web applications in Elixir; Configure Phoenix forms to capture and transmit user actions to backend processes; Map interface interactions directly to Elixir functional logic and GenServer states; Implement modern LiveView-inspired reactive patterns for real-time state updates; Manage concurrent user sessions and handle state recovery; Apply best practices for clean separation of concerns between UI and business logic. The course begins with essential architectural definitions and foundational Elixir communication patterns, then guides you through building and refactoring a robust interface connection step-by-step. This course is designed for web developers and Elixir beginners who want to move beyond static pages and build highly interactive, stateful web systems. No advanced architecture experience is required, though a basic familiarity with Elixir syntax is recommended. Start reading to master the bridge between Phoenix and Elixir today.
