Published on npm as @hypertill/db

Reactive local-first data for Expo and React Native.

Hypertill DB gives teams a real npm package, native SQLite performance, reactive reads, and a working TypeScript Expo reference app instead of a private local fork workflow.

Current package reality

Reactive reads today use withObservables.
Writes and imperative access use useDatabase.
The TypeScript Expo demo is the fastest reference.

Why It Works

Designed like a product site, not a patched library mirror.

Native SQLite

Keep data in the engine until you actually need it.

Hypertill DB is built for local-first apps that should stay fast as the dataset grows.

Expo Workflow

Install from npm and wire native setup through the packaged Expo plugin.

The current package story is designed around Android and iOS native builds, not manual local patching.

Reactive UI

Use the current React surface without inventing your own database runtime.

DatabaseProvider, useDatabase, and withObservables are the supported building blocks in 0.0.1.

Read These First

The shortest path from install to a working app.

Install

Use the published package, register the Expo plugin, and build a native client.
