React Doctor
Use React Doctor to scan a React codebase for security, performance, correctness, and architecture issues. Use the diagnostics to prioritize fixes and improve overall code health.
Usage
npx -y react-doctor@latest . --verbose
Use @latest intentionally to run the newest rule set.
Workflow
- Run the command at the project root and capture the full output.
- Verify diagnostics before patching: confirm each reported issue against actual runtime behavior, project conventions, and framework constraints.
- Fix validated issues, starting with highest severity diagnostics.
- Re-run React Doctor and confirm the diagnostics list is reduced.
- Re-run project checks (lint, tests, typecheck/build as applicable) to ensure no regressions.
