What it does

TinyBase is a reactive data store and sync engine for JavaScript and TypeScript: in-memory tabular and key-value data, bindings for React, Svelte and Solid, persistence and synchronization through a CRDT-based MergeableStore. For agents the repository ships the build-with-tinybase skill. It drives building a local-first app: it helps choose between Store and MergeableStore, set up schemas and UI bindings, browser or database persistence and synchronization, and diagnose an existing app. The skill suggests relying on a freshly generated project via npm create tinybase rather than reconstructing the setup from memory.

Who it is for. For frontend and full-stack developers building local-first apps on reactive data.

Example request

Build a local-first todo app on TinyBase with browser persistence and React bindings

Limitations

The skill targets TinyBase development and does not replace a server database when data is unbounded or queried on a server. It guides scaffolding and verification, but the code and its execution stay with you. TinyBase is a library and must be added to the project.

How to disable. Remove the build-with-tinybase skill folder from the agent's skills directory.

Security check

• The skill provides methodology and project generation; you run the code

README in short

The README describes TinyBase as a compact reactive data store and sync engine for JavaScript and TypeScript. It supports tabular and key-value data, schemas, queries, metrics, indexes, bindings for React, Svelte and Solid, and persistence and synchronization through a CRDT-based MergeableStore. The repository ships the build-with-tinybase Agent Skill that helps scaffold and verify TinyBase apps and relies on project generation via npm create tinybase. Docs and examples are on the project site, MIT licensed.

name: build-with-tinybase
description: Scaffold, extend, and verify reactive local-first JavaScript or TypeScript applications with TinyBase. Use when choosing TinyBase for in-memory tabular or key-value state, generating an app with create-tinybase, adding schemas or UI bindings, configuring browser or database persistence, configuring MergeableStore synchronization, or diagnosing an existing TinyBase application.

# Build With TinyBase

Prefer a current generated application over reconstructing TinyBase setup from memory. Preserve persistence and synchronization lifecycle ordering, and verify the behavior the user actually needs.
