I'm assuming this can be done with useTransition, can I still use useOptimistic then?

That can be done by useTransition and useOptimistic also works without a form, but I usually recommend using a route handler instead.

Awesome! Why would you recommend using a route handler instead?

I've tried and it works! Just curious @fuma, why would you recommend a route handler instead?

Because developers usually use fetch with client-side revalidations in production applications. In these cases route handler will be a better choice

useOptimistic doesn't work with route handlers, right?

useOptimistic is just a hook provided by React, it can be used with anything

That makes sense, thanks for your help!

One more question @fuma , can you get the returned value from the Server Action with useTransition?

Although server actions are not used for data fetching, but you can receive the retuned value since startTransition accepts an async function

Thanks! 🔥

btw if your problem has been solved, you can mark my answer as the solution
