RxDB

A NoSQL database for JavaScript that runs directly inside the application to store data locally, provide zero-latency queries while offline, and synchronize data with a backend. It is for developers and engineering teams building JavaScript applications for businesses that need offline-capable and realtime functionality. It is positioned with a local-first approach that stores data on the client and uses a sync engine with prebuilt replication plugins for many backends and observable realtime queries.
