# RxDB

A JavaScript NoSQL database that runs in-browser or in-app, providing local-first offline storage and synchronization with any backend.

**Route:** surfaced by the Web Application and Frontend Hosting Platform lane's de-branded queries → dependency to vercel.com.

**Why it's on the map:** Vercel's deployed applications commonly need client-side data persistence that continues working offline and syncs back when online — RxDB provides that local-first database capability that a Vercel-hosted app would depend on for offline functionality.

**Receipts** (verbatim from its page this run):

> RxDB is a NoSQL database for JavaScript that runs directly in your app

> delivers zero-latency queries even offline, and syncs seamlessly with any backend

**Edges:**
