With just these two lines, we've let our configuration know that we want to interact with a PostgreSQL database. If you already have a PostgreSQL database running locally, that's great. You'll be able to continue the rest of this guide locally and see the results when browsing localhost. If you don't have PostgreSQL, don't fret—we'll show you just how easy it is to deploy this app on Heroku, which will take care of the infrastructure for you.
