How to Set Up Environment Variables?

Setting up environment variables can vary depending on your system and the tools you are using. Here are some common methods:
Using .env files: Create a .env file in your project root and list your variables in KEY=VALUE format. For example:
SMTP_SERVER=smtp.example.com
API_KEY=your_api_key_here
Operating System Environment Variables: You can set environment variables directly in your operating system. For example, in Linux or macOS, you can use the export command:
export SMTP_SERVER=smtp.example.com
export API_KEY=your_api_key_here
Platform-Specific Settings: Many cloud platforms like Heroku or AWS allow you to set environment variables through their dashboards or CLI tools.
