We're excited to announce that[Dotenv Linter](https://github.com/dotenv-linter/dotenv-linter) is now supported on CodeRabbit!

-**Dotenv Linter**: A fast, opinionated linter for`.env` files. It helps prevent misconfigurations by detecting typos, invalid syntax, and duplicated keys.

Here's why you'll love it:

- 🧪**Catches common mistakes** in environment files before they cause runtime errors.

- 🚀**Super fast** with zero config required.

- 📦**Supports multiple`.env` formats** like`.env.local`,`.env.production`, and more.

For more details, visit our[tools documentation](https://docs.coderabbit.ai/tools/dotenv).

**Dotenv Linter** is a lightning-fast linter for`.env` files. It helps ensure your environment files are consistent, typo-free, and follow best practices.

CodeRabbit automatically detects`.env`,`.env.local`, and other dotenv-style files and runs`dotenv-linter` on them.

Issues like key duplication, missing values, incorrect formatting, or invalid characters are flagged directly in pull request reviews.

Dotenv Linter works out-of-the-box with zero config. But if needed, you can ignore rules or configure behavior via comments in the`.env` file or project-level config.
