Environment Variables

The application uses environment variables to manage configuration across different environments (Development, Production, etc.).

🔧 Setup

  1. Copy .env.example to create your local .env file: 
    cp .env.example .env
  2. Fill in the values for each variable.
  3. DO NOT COMMIT your .env file to version control.
