How to refactor code safely: a step by step approach for production systems
📰 Dev.to AI
Learn a step-by-step approach to safely refactor production code using small, measurable steps and strong test coverage
Action Steps
- Use compiler and type-system guarantees as safety nets to catch regressions early
- Write tests that enforce external boundaries and validate functionality
- Prefer incremental changes over big-bang rewrites to minimize risk
- Implement explicit quality gates to ensure code quality and stability
- Apply a safety net approach to rely on compiler's type checks and strict invariants
