Using SignalDB with React: A complete guide

SignalDB is a new client-side JavaScript database introduced in July 2023, designed specifically for modern web applications with a focus on reactivity and real-time data synchronization. It uses signals, similar to SolidJS, to automatically update data between components and a local in-memory or persistent database, making it an ideal solution for state management in React applications. SignalDB offers a MongoDB-like interface with TypeScript support and integrates with various JavaScript frameworks like React, Angular, and Vue.js. It allows for seamless data updates and real-time interaction without the latency associated with server-side databases. SignalDB supports multiple data persistence options, such as localStorage and Firebase, providing flexibility in storage approaches. Despite its benefits, such as supporting optimistic UI and offline-first design, SignalDB's automatic updates can complicate debugging, and its newness means limited documentation. While comparable to MongoDB in querying and persistence, SignalDB is client-side, enabling faster local data access but can be used alongside MongoDB for backend persistence in React applications.
