SignalDB

SignalDB is a client-side database optimized for modern web applications. It provides an optimistic UI for creating responsive and dynamic interfaces, a MongoDB-like interface for familiarity, and robust TypeScript support to ensure type safety and accelerate development. SignalDB enables versatile local data persistence with support for various storage providers and facilitates real-time updates by gathering and synchronizing data from multiple sources. Its framework-agnostic design makes it suitable for projects of any scale, offering instant data access with minimal latency, which is ideal for applications requiring fast data handling and real-time interactions. Adapters are available for popular reactive libraries, including Angular, React, Solid, Svelte and Vue.js.
