Implementing Optimistic Updates
Learn to provide an instant user experience by implementing optimistic updates with tRPC and a client-side cache.
Instant Feedback with Optimistic Updates
Imagine clicking 'Like' on a post. You expect it to show 'Liked' instantly, right? That's the magic of Optimistic Updates!
Optimistic updates make your app feel incredibly fast and responsive. They improve the user experience by giving immediate feedback.
What Are Optimistic Updates?
An optimistic update means updating the user interface (UI) before the server has confirmed the change. You 'optimistically' assume the server request will succeed.
- Instant UI update: The user sees their action immediately reflected.
- Background server call: The actual data change is sent to the backend.
- Rollback on error: If the server fails, the UI reverts to its previous state.
