Real-Time Web Architecture with Elixir and Phoenix

Modern web users expect instant updates, but building reliable real-time systems requires a solid understanding of how data flows between the client and the server. This text-based course guides you through the core architectural layers of soft real-time applications using the powerful Elixir programming language and Phoenix framework. You will transition from a beginner to a confident developer capable of structuring, debugging, and optimizing real-time communication. By studying the distinct responsibilities of each layer, you will learn how to handle concurrent connections efficiently without compromising system stability. What you'll learn: - Understand the foundational concepts of soft real-time systems and how Elixir's concurrency model supports them. - Map the flow of data across the client, communication, and server layers. - Configure Phoenix Channels and PubSub to manage real-time messaging and state. - Practice writing clean Elixir code to handle asynchronous events and process crashes. - Explore modern LiveView principles and basic telemetry for monitoring system health. - Apply pattern matching and supervision trees to build fault-tolerant connection layers. The course begins with essential terminology and the theory of soft real-time communication before moving step-by-step through client-side integration, transport protocols, and server-side state management. You will read structured explanations, analyze clear code snippets, and complete written exercises to reinforce your architectural knowledge. This course is designed for web developers and programming enthusiasts who are new to real-time architectures, Elixir, or Phoenix. No prior experience with functional programming is required, as we start with the absolute fundamentals. Start reading today to master the underlying mechanics of modern real-time web applications.
