# What is React Doctor?

React Doctor deterministically scans React code for issues across state and effects, performance, architecture, security, and accessibility.

Run React Doctor from a project root:

```bash
npx react-doctor@latest
```

To check every pull request, install the CI workflow:

```bash
npx react-doctor@latest ci install
```

React Doctor supports React, Next.js, Vite, TanStack, React Native, Expo, and Preact projects.

## How it fits with linting

React Doctor complements your existing lint setup. The CLI runs its curated rules, dead-code analysis, and dependency checks. It also adopts JSON ESLint or oxlint configuration when present. You can run the standalone plugins when you want React Doctor diagnostics inside an existing lint command.
