Today we're getting Dapper with Sapper! A framework built on top of Svelte!
It's a full stack framework like Next.js, meaning it has both frontend and backend functionality built in!
Also it's pretty straight forward to pick up! It doesn't add that much more complexity, making it relatively simple to start coding right away.
In fact we managed to read through all the documentation in this video! Impressive!
