SignalDB is a client-side database optimized for modern web applications, offering a MongoDB-like interface with robust TypeScript support to improve development speed and ensure type safety. SignalDB supports creating an optimistic UI for responsive, dynamic interfaces and offers versatile local data persistence with various storage providers. SignalDB is also able to gather data from multiple sources, enabling real-time updates and synchronization (see examples for AppWrite, Firebase, Supabase, RxDB and HTTP). Designed for efficiency in applications requiring quick data handling and real-time interactions, SignalDB provides instant data access, minimizing latency typical of server-side databases. Its lightweight architecture is framework-agnostic, making it suitable for both small and large-scale projects that require flexible, intuitive data management solutions. SignalDB provides adapters for popular reactive libraries including Angular, React (through 3rd party signal libraries), Solid.js, Vue.js and many more.

Questions and Answers

As answered by people managing SignalDB and ShareDB.

What's the story behind your product?

SignalDB's answer

The creator of SignalDB, Max Nowack, was inspired by his past experiences working with Meteor.js, which offered a seamless developer experience, particularly in handling real-time data synchronization and reactivity. Over time, as he explored other frameworks and tools like Apollo/GraphQL, FeathersJS, Firebase, Appwrite, Supabase, and RxDB, he found that none of them matched the Developer Experience of Minimongo and Meteor on the frontend side. The discovery of signals in SolidJS led him to grasp its connection to the reactivity he had previously worked with in Meteor, which eventually inspired the creation of SignalDB to bring Meteor-like reactivity to modern JavaScript frameworks.
