/List-with-Postgres-and-useOptimistic-nextjs15-react19

A list with useOptimistic, server actions(...) to test client-side interation with postgresql server delaying

Primary LanguageTypeScript

This project started as a simple list application to experiment with React's useOptimistic, startTransition, and server actions.

I kinda overengineered a bit ¯_(ツ)_/¯

The goal of this app is to create an experience that simulates a client-side application while saving and updating data in the background using a PostgreSQL database on a server that is lagging.
