What are environment variable tools and how do they work?

Environment variable tools are utilities that help manage environment variables in software development. They allow you to set, modify, and retrieve environment variables that can affect the behavior of applications.

Can you give me some examples of these tools?

Sure! Some popular environment variable tools include Dotenv, Envman, and Cross-env. Each of these tools helps manage environment variables in different ways.

How do I use Dotenv in my project?

To use Dotenv, first install it via npm. Then, create a .env file in your project root and define your variables there. Finally, require it at the top of your main file to load the variables into your application.

Are there any security concerns with using environment variables?

Yes, it's important to avoid committing your .env files to version control, as they may contain sensitive information like API keys. Use .gitignore to prevent this.
