Definition

ENV files (.env) store environment variables and configuration settings, particularly API keys and sensitive credentials for AI applications.

How It Works

ENV files use simple KEY=VALUE pairs, one per line. Applications load these variables at runtime, keeping sensitive data separate from code.

The format supports comments and multiline values, with libraries like python-dotenv parsing them into environment variables.

Why It Matters

ENV files prevent accidental exposure of API keys in version control. They enable different configurations for development, testing, and production environments.

Every AI application using cloud APIs relies on ENV files for secure credential management.
