Designing Elixir Applications with Ecto Best Practices

Structuring an Elixir application for long-term maintainability can be challenging when database queries and business logic become tightly coupled. This text-based course guides you through clean architectural patterns in Elixir, showing you how to isolate side effects, design clear boundaries, and write highly testable code. You will learn to think in systems, separating pure functional logic from database interactions. What you'll learn: - Understand foundational Elixir design principles and how Ecto fits into a clean architecture. - Separate pure business logic from impure database operations to improve code reliability. - Organize domain logic effectively using Ecto contexts and repository patterns. - Design modular applications using Elixir umbrella projects to manage growing codebases. - Apply modern testing strategies using Ecto sandbox and explicit boundaries. - Implement schema-less queries and custom validations for flexible data processing. This course begins with essential architectural definitions before guiding you through step-by-step structural transformations and design patterns. It is designed for developers who have a basic grasp of Elixir syntax and want to learn professional application architecture.
