The local Database for JavaScript Applications
- Realtime Queries
- Realtime Replication
- Works Offline
- Supports all JavaScript runtimes
- Great Performance
From the results of a query, to a single field of a document, with RxDB you can observe everything. This enables you to build realtime applications fast and reliable. Whenever your data changes, your UI reflects the new state.
RxDB supports replication with a CouchDB server or any custom GraphQL endpoint which smoothly integrates with your existing infrastructure. Also you can use the replication primitives plugin to create custom replications over any protocol like REST, Websocket, p2p or Firestore.
RxDB follows the Offline First paradigm where an application must work as well offline as it does online. This is done by persisting data on the client side and replicating it in the background. RxDB can even be used solely on the client side, with no backend at all.
RxDB is based on a storage interface that enables you to swap out the underlying storage engine. This increases code reuse because the same database code can be used in any JavaScript runtime by just switching out the storage settings.
