TypeScript Structure & Architecture FAQs

Question 1

Why does this skill discourage default exports?

Accepted Answer

Named exports are preferred because they provide better IDE autocomplete, allow for easier refactoring, and ensure consistent naming across the entire codebase.

Question 2

How does this skill improve tree-shaking?

Accepted Answer

By enforcing explicit re-exports and avoiding 'export *' in barrel files, the skill ensures that build tools can accurately identify and prune unused code from your production bundle.

Question 3

Is this skill compatible with both frontend and backend projects?

Accepted Answer

Yes, these structural guidelines and TypeScript best practices are universal and apply to Node.js backends, React/Vue frontends, and shared libraries.

Question 4

What is the benefit of feature-based directory organization?

Accepted Answer

Organizing code by feature (e.g., user, order) rather than technical type (e.g., controller, model) makes it easier to locate related logic and reduces the cognitive load of navigating large projects.

Question 5

How does it handle circular dependencies?

Accepted Answer

The skill provides guidance on using tools like Madge for detection and suggests refactoring patterns, such as extracting shared types or interfaces into independent files.
