Hi @laribright8,

There are a few ways to load them up.

  • Loaded from environment variables,
  • Loaded from a JSON file on disk,

Environment variables can be access by the object process.env.NameOfVariable.

Having said that, I’ll recommend checking out the following tutorial as it will help you better understand how to call and actually work with variables in nodejs - Tutorial

If you are referring to the App Platform service of DigitalOcean, then you can check the below link which explains how to use environment variables with the App Platform
