TanStack DB

The reactive client-first (local-first?) store for your API. TanStack DB gives you a reactive, client-first store for your API data with collections, live queries and optimistic mutations that keep your UI reactive, consistent and blazing fast... Built on a Typescript implementation of differential dataflow, TanStack DB gives you real-time sync, live queries and local writes. With no stale data, super fast re-rendering and sub-millisecond cross-collection queries — even for large complex apps. (data store) https://tanstack.com/db
