For centuries, members of the B’doul Bedouin tribe lived in the caves around the ancient city of Petra, Jordan. Then, in the 1980s, the government forced the tribe to move in the name of preserving the geological site for tourists. But if the residents are forced to leave, and if their heritage has been permanently changed, then what exactly is being preserved?

Ryan and Sam discuss the purpose and usage of the useOptimistic() hook, a new experimental API from React.

Topics include:

0:00 - Intro
2:18 - Problem: RSCs require a server roundtrip before the UI can be updated
10:13 - Solution: useOptimistic() lets you merge ephemeral client-side state with server-side data so you can update the UI during a Server Action or Transition
14:03 - How useOptimistic() avoids the notion of identity by discarding the ephemeral state after the app settles
21:17 - How useOptimistic() lets you safely “fork” state that eventually syncs with the server
27:32 - Handling error states
29:26 - Differences between useOptimistic() and Remix fetchers
34:57 - How useOptimistic() lets you avoid managing a long-lived client-side cache
