AI tools make large-scale code refactoring faster and safer by applying consistent transformations across a codebase. This guide covers the best refactoring patterns, tools, and how to verify AI-generated changes without breaking production code.
Five years of "just make it work" and your monolith has become a 300,000-line codebase that nobody fully understands. Functions call functions that call functions across domain boundaries. Every change is risky. Senior engineers hoard context. Onboarding takes months.
Incrementally replace a legacy system by routing new traffic through new code, gradually strangling the old system until it can be decommissioned.
Enable strict mode incrementally in large codebases. Use migration strategies, utility types, discriminated unions for errors, branded types for safety, and satisfies for inference.
