State Management in Elixir: Building Stateful Applications

Managing state in a highly concurrent, distributed system requires a shift in how we think about data flow. Elixir provides powerful, built-in primitives to handle state safely without relying on external databases for every operation. In this text-based course, you will transition from basic functional concepts to designing robust, stateful Elixir applications. You will learn to leverage OTP behaviors and persistent connection patterns to build responsive, real-time systems.\n\nWhat you'll learn:\n- Understand foundational state concepts and how Elixir handles immutability and processes\n- Implement GenServers and Agents to maintain state across concurrent operations\n- Design supervision trees to ensure state recovery and application fault tolerance\n- Configure Phoenix Channels and LiveView to manage real-time, persistent client-server state\n- Apply modern state-sharing patterns and pub/sub mechanisms safely in distributed environments\n\nThis course starts with the essential definitions of state and processes before guiding you through hands-on written exercises and code breakdowns. You will progress from simple memory-based state to building real-time, connected stateful flows.\n\nThis course is designed for developers new to Elixir who want to understand OTP and state management from the ground up, with no advanced prerequisites required.
