We were excited to host Software Engineer Cassidy Williams for this fun interactive event! Cassidy built a Hello World React App live with HarperDB. This code along is for developers of any skill level, and will help you sharpen your React skills, as well as app development and general database knowledge. We hope you enjoy, and if you like coding with HarperDB, you can use the code CASSIDY to upgrade to any paid instances. It is worth $250 in credits!
