Automated React codebase scanner that detects security, performance, correctness, and architecture issues. Generates a 0-100 diagnostic score with actionable findings across four categories: security vulnerabilities, performance bottlenecks, correctness errors, and architectural problems Designed for post-change workflows: run after code modifications, fix flagged issues, then re-run to verify improvements Supports verbose output and diff mode to highlight changes between scans Ideal for code review checkpoints, feature completion, and bug-fix verification in React projects 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 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 react-doctor@latest --verbose (without --diff) to scan the full codebase. Fix issues by severity — errors first, then warnings. Command npx react-doctor@latest --verbose --diff
