  Loads environment variables from .env for nodejs projects.

In my app here, I have the used a .env file to keep all these secret keys and using the dotenv node package https://www.npmjs.com/package/dotenv to manage my env variables and secret credentials. Basically this module loads environment variables from a .env file that you create and adds them to the process.env object that is made available to the application. Just remember NEVER EVER commit the .env file to Github. They also strongly recommend against committing your .env file to any version control. If you do, you will receive an email from Github and also from AWS informing you about this security breach in your account.
