This post describes how to create a REST API using Node, KOA and PostgreSQL. It’s intended for beginners but is based on best practice. Most articles for beginners will tell you to focus on understanding the basics and don’t worry about design practices. They are probably right but that’s just not how my mind works. You should have your development environment ready with Node, NPM and Git installed before starting. If you need help; look at my previous articles on setting up your web development environment and getting started with Git. All of the code is documented below but the complete application code is here https://github.com/infornite/n4nite-rest-api if you want to refer to it as you follow along.
