How can I use a config library in Node.js?

You can use libraries like config or dotenv to manage configuration settings in Node.js applications.

What are the benefits of using a config library?

Using a config library helps in managing environment variables, separating configuration from code, and making your app more flexible.

Can you show me a simple example of using dotenv?

Sure! First, install it using npm install dotenv. Then, create a .env file with your variables, and load it in your app with require('dotenv').config();.

Is it safe to store sensitive information in .env files?

It's generally safe as long as you don't commit your .env file to version control. Use .gitignore to exclude it.
