What is Tinybase State?
TinyBase is a lightweight, open-source JavaScript library that provides a reactive data store and synchronization engine. It allows developers to model both key-value and tabular data with optional typed schematization, offering features like built-in indexing, metric aggregation, tabular relationships, and a powerful query engine for selecting, joining, filtering, and grouping data reactively without SQL. It's designed for building fast, responsive applications by enabling granular listening to data changes, ensuring that only necessary UI components re-render.
TinyBase is particularly well-suited for local-first applications, where data is stored locally on the user's device and can function offline. It boasts a tiny footprint (5.4kB - 12.1kB with no dependencies) and includes native CRDT support for deterministic synchronization and merging of data across multiple sources, clients, and servers. While primarily an in-memory store, it offers easy persistence to various storage options like browser storage, IndexedDB, SQLite, PostgreSQL, and more. It also provides optional React bindings, pre-built components, an undo stack, and developer tools to streamline UI development.

Tinybase State FAQ
How does Tinybase State facilitate building highly responsive user interfaces?
TinyBase State enables highly reactive and performant UIs by allowing granular listening to data changes. This ensures that only the necessary UI components re-render when data is updated, leading to faster and more responsive applications.
Which teams would benefit most from using Tinybase State?
TinyBase State is ideal for development teams focused on building local-first and offline-first applications. It is also well-suited for teams that require complex data modeling with database-like features within their client-side applications.
What kind of data modeling capabilities does Tinybase State offer?
TinyBase State allows developers to model both key-value and tabular data, with optional typed schematization. It includes features like built-in indexing, metric aggregation, tabular relationships, and a powerful query engine for data manipulation without SQL.
How does Tinybase State compare to WatermelonDB for local-first development?
TinyBase State, like WatermelonDB, is designed for local-first applications and offers robust data synchronization capabilities with CRDT support. TinyBase State is a lightweight, dependency-free JavaScript library that provides a comprehensive reactive data store and sync engine for complex data modeling.
What are the main trade-offs when adopting Tinybase State?
A primary trade-off when adopting TinyBase State is that it requires JavaScript knowledge for implementation. Additionally, new users unfamiliar with reactive data patterns or CRDTs may experience a learning curve.
How is Tinybase State priced?
TinyBase State is free to use, as it is an open-source JavaScript library. There is no paid plan required to access its features and functionalities.
Can Tinybase State synchronize data across multiple devices or servers?
Yes, TinyBase State includes native CRDT (Conflict-free Replicated Data Type) support. This enables deterministic synchronization and merging of data across multiple sources, clients, and servers, facilitating robust data consistency.
