Full stack build with authentication/authorization

I've mostly build static sites but I'm venturing into full stack development, this is the biggest project I've completed so far and I think it turned out pretty well. I used Auth.js for the authentication/authorization with a Neon DB and Prisma. I'm looking forward to diving into these areas more in the future, mostly in regards to scaling and working in real world production setups alongside improved performance.

The biggest challenge for me was the bookmark setup for users, first time I've worked with that sort of concept of reflecting added/removed bookmarks instantly and keeping it in sync across pages. I'm looking forward to see how others set this up that will most likely be more efficient.
