React Doctor

Scans React codebases for security, performance, correctness, and architecture issues. Outputs a 0–100 health score.

After making React code changes:

Run npx -y react-doctor@latest . --verbose --diff and check the score did not regress.

If the score dropped, fix the regressions before committing.

For general cleanup or code improvement:

Run npx -y react-doctor@latest . --verbose (without --diff) to scan the full codebase. Fix issues by severity — errors first, then warnings.

Command

npx -y react-doctor@latest . --verbose --diff
