Full-stack Todo App with Remix

This was my first time building an app with Remix and learned a lot in the process.

The parts I had the most issues while implementing were:

• Optimistic UI for multiple ongoing todo creation requests: There wasn't an obvious way to do it, but after many attempts I think I got a good solution.

Since this is just a showcase app, I did not want users having to sign in to use it. So I made it so when a new user opens the app for the first time, they are automatically signed in with a visitor session, which lasts for 24 hours.
