# nuxt typecheck

> The typecheck command runs vue-tsc or Golar to check types throughout your app.

```bash [Terminal]
npx nuxt typecheck [ROOTDIR] [--cwd=<directory>] [--logLevel=<silent|info|verbose>] [--dotenv] [-e, --extends=<layer-name>] [--checker]
```

The `typecheck` command runs [`vue-tsc`](https://github.com/vuejs/language-tools/tree/master/packages/tsc) or [Golar](https://golar.dev/languages/vue/) to check types throughout your app. If neither is installed, you will be prompted to install one, or shown installation instructions when running in a non-interactive terminal.

This command sets `process.env.NODE_ENV` to `production`. To override, define `NODE_ENV` in a [`.env`](https://nuxt.com/docs/4.x/directory-structure/env) file or as a command-line argument.
