Frequently Asked Questions(click to expand)

What is a .env file?

A .env file stores environment variables as key-value pairs. It's used across Node.js, Python, Docker, and CI/CD systems to configure applications without hardcoding secrets.

How are quoted values handled?

Both single and double quoted values are supported. Quotes are stripped from the parsed value. Inline comments (# after value) are also handled correctly.
