# process.env
`process.env` is a Node.js object that contains all environment variables available to the current process. These can be set in the shell, in a `.env` file via a library like dotenv, or by the deployment platform. Configuration values like port numbers, API keys, and database URLs are commonly stored and accessed this way.
