Question

How to create environment variables?

I am new to DevOps and all this. I am using an Ubuntu server to host my node.js application. Previously it was hosted in heroku. In heroku there is a special area to store environment variables, but I don’t know how to store it here. I have tried creating a variable and then exporting, but it gets flushed as the server restarts. Please, someone, help me out!

Hi @nemo011,

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
