refactor

To refactor code without breaking tests or type safety, you need a process that verifies all existing tests pass and introduces no new type errors. This approach analyzes dependency graphs and maps architectural layers to prevent regressions while you restructure.

Safely restructuring code across architectural layers requires maintaining strict layer boundaries, such as Core, Service, and API. The refactoring process ensures dependency flow adheres to these architectural standards while preserving public APIs during the modification.

Maintaining public API signatures during code modifications requires verifying that function signatures and return types remain unchanged. Safe refactoring practices explicitly check these public interfaces against dependency graphs to ensure external contracts are preserved.

Yes, you can refactor a module like user authentication without regressions by ensuring all existing tests pass and type safety is maintained. The process analyzes module dependency graphs to guide safe structural changes without breaking existing functionality.

You should use an automated refactoring process when a new feature requires restructuring existing code and upholding architectural standards is critical. It prevents regressions by systematically verifying tests and types, which manual restructuring often misses.

Yes, safe refactoring works directly with existing test suites to verify code quality by ensuring all tests pass after code modifications. It integrates type safety checks and architectural layer mapping to guarantee the codebase remains maintainable.
