This app is meant to help demonstrate how easy it can be to migrate a Go application that renders HTML into a JSON API, and how nearly all of the logic in the application will remain unchanged. It intentionally starts out with a pretty poor design and structure so that we can look at the benefits of each individual set of changes we will be making.
To setup your local dev you will need to setup a PostgreSQL database. I provided a setup.sql file to help make that a little easier - you should be able to run it like this:
psql -f setup.sql
If you need help figuring our Postgres, I have a pretty in-depth series on using it here: https://www.calhoun.io/using-postgresql-with-go/
