Elixir Application Design: Building a Hero Selection System

Designing interactive applications in Elixir requires a solid grasp of functional architecture, state management, and user input handling. If you want to move beyond basic syntax and build structured, real-world workflows, learning how to model a character selection system is the perfect starting point. This text-based course guides you through the process of architecting a robust interactive selection system in Elixir. You will transition from writing simple scripts to designing clean, pipeline-driven applications that parse input, manage state transitions, and handle edge cases gracefully. What you will learn: 1. Learn the core principles of Elixir application design and functional architecture. 2. Parse and validate user input safely using pattern matching and guard clauses. 3. Build interactive command-line prompts with confirmation and rollback logic. 4. Design clean, readable data transformations using functional pipelines. 5. Implement basic state management concepts for interactive tools. 6. Write maintainable Elixir code using modern typespecs and ExUnit tests. You will start with foundational Elixir concepts, exploring how data flows through pure functions, before constructing a complete, interactive selection program. This course is designed for beginners who understand basic syntax and want to learn how to structure real-world application logic.
