Frequently Asked Questions

What is an .env file?

An .env file stores environment variables as KEY=VALUE pairs. It is used by Node.js (via dotenv), Docker, and most CI/CD platforms to configure applications without hardcoding values.

How are nested objects handled?

Nested objects are flattened using the selected separator. For example, { "db": { "host": "localhost" } } becomes DB_HOST=localhost with underscore separator.
