What is a .env file?
A .env file is a simple text file used to store environment variables for your application. These files typically contain configuration settings, API keys, database credentials, and other sensitive information that shouldn't be hardcoded in your source code.
.env File Format
The .env format follows simple rules:
- Each line contains a
KEY=valuepair - Lines starting with
#are comments - Values with spaces should be wrapped in quotes:
KEY="value with spaces" - Variable names should only contain letters, numbers, and underscores
- Empty lines are ignored
Common Issues
This tool detects several common .env file issues:
- Duplicate keys: Multiple definitions of the same variable
- Unquoted spaces: Values containing spaces that aren't properly quoted
- Invalid variable names: Names with special characters or starting with numbers
- Missing equals sign: Lines that look like variables but lack the = separator
Security Best Practices
- Never commit .env files to version control (add to .gitignore)
- Use different .env files for development, staging, and production
- Regularly rotate sensitive credentials
- Use the mask feature when sharing your screen or taking screenshots
