A reactive</emdata store & sync</emengine.
TinyBase lets you listen to changes made to any part of your data. This means your app will be fast, since you only spend rendering cycles on things that change. The optional bindings to React and pre-built components let you easily build fully reactive UIs on top of TinyBase. You even get a built-in undo stack, and developer tools!
Consumer app? Enterprise app? Or even a game? Model key-value data and tabular data with optional typed schematization, whatever its data structures. There are built-in indexing, metric aggregation, and tabular relationships APIs - and a powerful query engine to select, join, filter, and group data (reactively!) without SQL.
TinyBase has native CRDT support, meaning that you can deterministically synchronize and merge data across multiple sources, clients, and servers. And although TinyBase is an in-memory data store, you can easily persist your data to file, browser storage /persister-browser, IndexedDB, SQLite or PostgreSQL databases, and more.
TinyBase works anywhere that JavaScript does, but it's especially great for local-first apps: where data is stored locally on the user's device and that can be run offline. It's tiny by name, tiny by nature: just 5.3kB - 11.5kB and with no dependencies - yet 100% tested, fully documented, and of course, open source!
