# RxDB Documentation

> Authoritative reference documentation for RxDB, a reactive, local-first NoSQL database for JavaScript with offline support and explicit replication.

RxDB (Reactive Database) is a local-first, NoSQL database for JavaScript applications.
It stores data on the client (browser, Node.js, React Native, Electron, Capacitor) and optionally replicates with a backend server.
Data is modeled as JSON documents inside collections, validated by JSON Schema, and queried with the Mango/MongoDB query syntax.
All data access is reactive through RxJS Observables so that UI components update automatically when data changes.
