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

​
Files

Dotenv Linter will run on files with the following patterns:
  • **/.env
  • **/.env.*
We will not run against files that do not start with .env (e.g., test.env). However .env.dev or .env.local is fine.
Dotenv Linter does not require configuration to run and automatically anlysises .env files. If no configuration file is found, it will use default settings.

​
When we skip dotenv-linter

CodeRabbit will skip running dotenv-linter when:
  • No .env files are found in the pull request.
  • dotenv-linter is already running in GitHub workflows.

​
Notes

  • All dotenv-linter issues are treated as warnings (dotenv-linter does not distinguish severity levels).

​
Features

Dotenv Linter can detect:
  • Key duplication
  • Missing values
  • Incorrect formatting
  • Invalid characters
  • And many more issues
