Using Environmental Variables in NodeJS with DotEnv
Today, I'm going to show you how to hide secret keys and information in JavaScript using the JavaScript library called dotenv - which is used to access environment variables in a NodeJS project.
We will start a project, download the library, import the library, create some code, set up the .env file and create some variables, then run the code to call the variables in the main file.
Then we will be creating a more realistic example with the npm library opener to open a website url hidden as an environment variable.
So let's start!
