Concurrent Elixir with GenServer and Anonymous Functions

Elixir's concurrency model is incredibly powerful, but managing long-running background tasks without blocking your main application requires a solid understanding of OTP behaviors. This text-based course guides you through the process of building robust, self-healing background jobs from scratch. You will transition from writing basic Elixir code to structuring resilient, concurrent workflows that handle failures gracefully. By understanding how to pass execution logic dynamically using anonymous functions, you will build highly reusable GenServer components that can manage retries, handle errors, and scale effortlessly. What you'll learn: Understand the foundational concepts of Elixir concurrency, processes, and state management; Implement anonymous functions to pass dynamic execution logic into generic workers; Configure GenServers to manage long-running concurrent jobs without blocking the main application thread; Apply modern supervision trees and Task-based patterns to monitor and restart failing processes; Design resilient error-handling and retry mechanisms for background tasks; Practice building clean, maintainable Elixir code structures using current best practices. This course starts with the core terminology of processes and message passing before diving into step-by-step implementations of GenServers and supervisor strategies. Through clear written explanations and practical code examples, you will learn to architect reliable concurrent systems. This course is designed for beginner to intermediate Elixir developers who want to deepen their understanding of concurrency and OTP behaviors. No prior experience with GenServers is required.
