How do environment variables differ across various frameworks?

Environment variables can vary significantly between frameworks. For example, in Node.js, you typically use the 'process.env' object, while in Django, you might use the 'os.environ' module. What specific frameworks are you interested in?

I'm mainly working with React and Express. How do they handle environment variables?

In React, you usually define environment variables in a .env file and access them using 'process.env.REACT_APP_YOUR_VARIABLE'. In Express, you can use the 'dotenv' package to load variables from a .env file into 'process.env'. Both frameworks allow you to manage sensitive information securely.

Are there any best practices for using environment variables?

Yes, some best practices include: never hardcoding sensitive information, using a .env file for local development, and ensuring that your .env file is included in your .gitignore to prevent it from being pushed to version control.

What about using environment variables in production?

In production, it's best to set environment variables directly on the server or use a secrets management tool. This way, you avoid exposing sensitive data in your codebase.
