Designing Elixir Applications: Build a Text-Based Dungeon Crawler

Learning Elixir is one of the best ways to master functional programming, but moving from basic syntax to designing structured applications can feel like a major leap. In this text-only course, you will learn how to design clean, maintainable Elixir applications by building a text-based dungeon crawler. You will start with the fundamental building blocks of functional design and progress to managing complex game state, structuring actions, and writing testable code. What you'll learn: - Model game entities using Elixir structs and enforce data integrity - Implement interactive game logic using powerful pattern matching and guard clauses - Structure reusable functions and refactor code for maximum readability - Manage application state and transitions using functional pipelines - Write type specifications and document your domain logic using modern Elixir standards - Verify your game mechanics with clean, automated unit tests using ExUnit The course begins with foundational concepts, defining Elixir structs for rooms, players, and actions. You will then learn how to compose functions, handle state transitions, and continuously refactor your codebase into a polished, modular architecture. This course is designed for beginner Elixir developers who understand basic syntax and want to learn practical software design principles. No advanced programming experience is required. Start reading today to elevate your functional programming skills and build structured Elixir applications.
