Web App with OTP
You know about GenServers, you've heard about Phoenix, but you're not quite sure how they can work together to create a web application.
This series was made for those wanting to bridge that gap. In it we'll build a web application that tracks the prices of different cryptocurrencies. We'll start by fetching data from an API and managing that state in a GenServer.
We'll then add an interface with Phoenix and persist data to the database so it's not deleted when we restart our application.
