SignalDB | reactive local javascript database

Reactive, Local-First JavaScript Database with Real-Time Sync

Optimistic UI, Real-time sync, TypeScript support, MongoDB-like queries and signal-based reactivity every framework.

Signal-based Reactivity!

SignalDB offers a universal interface that works with any JavaScript framework or library. Achieve reactivity by using reactivity adapters. We provide pre-built adapters for numerous libraries including Angular, Solid.js, Preact, Vue, and others!

MongoDB-like interface

You don't have to learn new things. The API of SignalDB is similar to that of MongoDB. Thanks to the awesome mingo library, you can use your common selectors.

Real-Time Synchronization

SignalDB’s sync feature ensures data consistency across collections and supports any backend, including REST APIs and GraphQL. It also includes built-in conflict resolution to manage data discrepancies effectively.

🔵

simple

SignalDB's schema-less design and in-memory storage significantly enhance the Developer Experience by simplifying data management and ensuring rapid query performance.

Solid.js

Solid.js's granular reactivity and efficient data management provide a robust foundation for SignalDB, enabling the creation and management of signals which are core reactive primitives, thereby allowing for real-time data updates and synchronization.

React

SignalDB's reactivity adapters allow for seamless integration with signal libraries, enabling auto-updates to reactive queries whenever data changes, which aligns well with React's reactivity model.

Vue

Vue.js's powerful reactivity system, which allows for effortless binding and updating of the UI based on data changes, pairs well with SignalDB's reactivity adapters, creating a fusion of two reactivity paradigms and ensuring real-time data accuracy.

🥳

and many more!

SignalDB is designed to be framework-agnostic, offering integration through reactivity adapters which allow it to seamlessly interface with various signal libraries, ensuring auto-updates to reactive queries when data changes; this flexibility makes it a great choice for integration with a wide range of frameworks
