.env.save
The .env.save file is a backup or secondary version of the .env file, which contains environment variables used by applications to manage configuration settings outside of the codebase. Here are some key points regarding .env.save:
-
Purpose: The primary purpose of a .env.save file is to provide a backup of the .env settings. This is useful in development environments where configuration changes are frequent, or during deployments where configuration might need to be reverted.
-
Usage: Developers often use .env.save files to store a copy of their environment variables before making significant changes or before deploying to a new environment. This ensures that if something goes wrong, they can quickly revert to a known working configuration.
-
Security: Just like the .env file, .env.save should not be committed to version control systems like Git due to security concerns. Sensitive information like API keys, database credentials, or any other secret should be protected.
-
Best Practices:
- Do not track .env.save in version control. Use .gitignore to exclude it.
- Keep the .env.save file in a secure location, similar to the .env file.
- Ensure that the permissions on the .env.save file are set so that only necessary users or processes can access it.
-
Context: The concept of saving environment configurations has been around since the rise of 12-factor app methodology, which advocates for the separation of configuration from code. The .env.save file emerged as a practical solution for developers needing to manage and backup their configuration settings efficiently.
-
Tools and Frameworks: Various tools and frameworks support or encourage the use of .env files and by extension, backup files like .env.save. Examples include:
