What are the differences between cross-env and dotenv?
Cross-env is a package that allows you to set environment variables across different operating systems, while dotenv is used to load environment variables from a .env file into process.env.
Can you give me an example of how to use both in a project?
Sure! With dotenv, you would create a .env file with your variables, and then use require('dotenv').config()
in your code. For cross-env, you would set environment variables in your npm scripts like this: cross-env NODE_ENV=production node app.js
.
Which one should I use for my Node.js application?
It depends on your needs. Use dotenv if you want to manage environment variables from a file, and cross-env if you need to ensure compatibility across different OS environments.
