# 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
```bash
npx react-doctor@latest --verbose --diff
```
| Flag | Purpose |
| ----------- | --------------------------------------------- |
| `.` | Scan current directory |
| `--verbose` | Show affected files and line numbers per rule |
| `--diff` | Only scan changed files vs base branch |
| `--score` | Output only the numeric score |
