The Path Through Legacy: Delicate Balance Between Tolerance and Phobia
summary
Presents a concrete approach to decide whether to tolerate or excise legacy code by showing actual steps: a refactoring checklist, use of React 18 features to isolate and modernize components, pragmatic component migration patterns, when to write codemods versus add tests, and how to measure progress with concrete signals rather than gut feeling. Includes a worked example of incrementally replacing components and the failure modes that force rollback.
