To structure software modules using Domain-Driven Design and Clean Architecture, follow best practices for separation of concerns, domain-specific naming, and early return patterns to ensure a maintainable and robust codebase.

The library-first approach in software architecture promotes using existing libraries and services over custom implementations for common functionalities, ensuring code reusability and reducing duplication.

You need Clean Architecture when developing quality-focused software that requires maintainability and robust codebases, ensuring your code structure remains domain-aligned and separated from external concerns.

Anti-patterns to avoid in Domain-Driven Design include poor naming conventions, logic duplication, and ignoring separation of concerns, which compromise code quality and domain alignment.

You can apply DDD principles to improve code quality by enforcing rules for code structure, readability, and reusability, utilizing domain-specific naming and early return patterns.

The best way to decide between custom logic and external libraries is adopting a library-first approach, evaluating if common functionalities can be handled by existing services before building custom implementations.
