# Linting
The Next.js repository runs [ESLint ](https://eslint.org ), [Prettier ](https://prettier.io ) and [alex ](https://alexjs.com ) to lint and format all code and documentation.
To lint all code you can run:
```sh
pnpm lint
```
If you get errors, you can run the ESLint and Prettier auto-fix using:
```sh
pnpm lint-fix
```

Not all rules can be auto-fixed, some require manual changes.
