RxDB, which stands for Reactive Database, is a JavaScript-based NoSQL database designed for a wide range of applications such as websites, hybrid apps, Electron apps, progressive web apps, and Node.js. The "reactive" aspect of RxDB allows you not only to retrieve the current state of the database but also to subscribe to all changes in the state, including query results or specific fields within a document. This feature is particularly advantageous for real-time user interface applications, as it facilitates development and offers notable performance benefits. Additionally, RxDB can be utilized to build efficient backends in Node.js.

Questions and Answers

As answered by people managing RxDB and SignalDB.

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.

Which are the primary technologies used for building your product?

SignalDB's answer:

JavaScript, TypeScript

What makes your product unique?

  • Ask HN: How Can I Make My Front End React to Database Changes in Real-Time?
    I'm interested in this problem also! I think there is a large overlap with projects that market/focus on offline-first experiences. AFAIK this problem can be solved by: 1) Considering a client-side copy of the database that gets synced with the remote DB. This is an approach [PowerSync](https://www.powersync.com/) and [ElectricSql](https://electric-sql.com/) and [rxdb](https://rxdb.info/) take! - Source: Hacker News / 14 days ago
  • You can't leak users' data if you don't hold it
    Hey, after I posted that, I went and gave a second look online to see if I could find something that would allow me to develop a local-first app with offline persistence and syncing capabilities. I ended up finding some possibilities out there that could potentially help me build stuff. One of them is RxDB [1], which offers WebRTC syncing - you'd still need a signaling server, I suppose, but all sensitive... - Source: Hacker News / about 1 month ago
  • SignalDB: Bringing Meteor-Like Reactivity to the Modern Age
    About a year ago, I discovered a cool offline-first framework called RxDB. Initially, I thought that on the frontend side, this was exactly what I had been searching for over the past years. After tinkering around and even using it in production for some time, I realized that it wasn't well-suited for my intended use. RxDB was initially created as an RxJS layer for PouchDB with a server replication interface.... - Source: dev.to / 6 months ago

    Congrats to the team. Once I’ve tried https://rxdb.info/ and it wasn’t funny at all to do the remote replication (PG) and to deal with conflicts. I do need to check this out! - Source: Hacker News / 7 months ago
