## What it is
TinyBase is a reactive in-memory data store and sync engine for local-first JavaScript and TypeScript apps, supporting tabular and keyed-value data with optional typed schemas. It offers CRDT-based synchronization, persistence to browser storage/SQLite/PostgreSQL, and UI bindings for React, Solid, and Svelte in a tiny dependency-free bundle.

## Use cases
- build a local-first offline-capable web app with sync
- manage reactive app state in React with fine-grained updates
- synchronize data across clients and servers with CRDTs
- persist app data to IndexedDB or SQLite in the browser
- build a real-time collaborative app like chat or drawing
- query and join tabular data reactively without SQL

## When to choose
- you need offline-first apps that stay consistent when back online
- you want a tiny (7-16kB), dependency-free reactive store
- you need built-in sync, persistence, indexes, and a query engine in one library
- you use React, Solid, or Svelte and want reactive UI bindings

## When to avoid
- you need a full SQL database with complex server-side queries
- your stack is not JavaScript/TypeScript
- you need heavy relational database features like stored procedures or transactions across services

## Facets
- artifact type: library
