When you use process.env, you retrieve environment variables as strings. If a variable is not set, accessing it returns undefined. Common use cases include:

  • Storing secret keys and passwords;
  • Configuring database connection details;
  • Setting application mode (such as "development" or "production");
  • Defining API endpoints or feature flags.

Always be cautious when working with environment variables. Avoid printing sensitive values to logs or exposing them in client-side code. Use environment variable management tools or .env files with care, ensuring these files are not committed to public repositories. This helps maintain the security and flexibility of your applications.
