To refactor legacy code for modularity and decoupling, apply single responsibility principles, minimize public API surfaces, and use dependency injection to break tight coupling, making the codebase easier to modify and test.

Design patterns for single responsibility and dependency injection focus on creating small, focused files, using descriptive naming conventions, and composing simple functions to ensure predictable, testable behavior across your modules.

To structure your codebase for AI-assisted editing, optimize AI-readability by using clear naming conventions, grouping files by domain, and enforcing parameter independence so AI tools can reliably reason about and modify the code.

Yes, these software architecture principles apply across backend, frontend, and library projects, providing actionable guidance for API design, dependency management, and code organization regardless of the specific platform.

The best way to reduce cognitive load in module API design is to maintain minimal public APIs, group modules by domain, and enforce single responsibility, which keeps files focused and makes the system easier to understand.

Avoiding circular dependencies is crucial because it enables robust composition of simple functions, prevents fragile tightly-coupled code, and ensures that modules remain independently testable and maintainable.
