What problem does it solve?
Upgrading a React 17 codebase to React 18 safely requires careful planning, phased execution, and validation to avoid breaking changes, performance regressions, or SSR incompatibilities.
Core Features & Use Cases
- Provides a phased upgrade plan that covers dependencies, rendering API changes, automatic batching, Strict Mode adjustments, testing updates, and React 19 preparation.
- Includes practical guidance and real-world pitfalls to audit multiple entrypoints, root rendering patterns, and module compatibility.
- Useful for teams modernizing large React apps, especially those with SSR or custom wrappers, and for validating compatibility before production.
