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.

  • Using CRDTs to build collaborative Rust web applications
    If you plan to build production-grade CRDT-based software and don’t want to build every piece of it by hand, I recommend Automerge as a library for handling all your CRDT needs, but it’s always good to look under the hood to build intuition and understanding for the underlying concepts. - Source: dev.to / 3 months ago
  • Figma Is a File Editor
    Take a look at https://automerge.org/ and the stack those folks are building. You're exactly right that it's a difficult balance (specifically the trick is proving commutativity for the domain-specific data of your application). But automerge (and then https://github.com/inkandswitch/peritext) show it's at least possible. Good stuff. - Source: Hacker News / 11 months ago

  • HackNote
    Some years ago "offline-first" was a thing: https://web.archive.org/web/20170720174332/http://hood.ie/initiatives/#offline-first Primarily based on PouchDB/CouchDB. Now the site redirects to RxDB. https://rxdb.info/ There's still a site by that name but I don't quite understand what's the intention https://offlinefirst.org/. - Source: Hacker News / 12 days ago
  • 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 / about 2 months 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 / 2 months 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 / 7 months ago
  • Show HN: ElectricSQL, Postgres to SQLite active-active sync for local-first apps
    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 / 9 months ago
