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.

  • I built a WebComponents-based framework
    Looks really cool, I like to make very minimalistic dependency choices for the web apps I work on. Web Components look interesting and it's great to see frameworks that build upon it and provide features that are currently missing from it. When I landed on the page I remembered another Realm framework I used a lot long time ago. https://realm.io has the same name and the logo looks very similar too. Not sure if... - Source: Hacker News / 7 months ago
  • Realm Database, Expo SDK 49 and Expo Router Getting Started
    Realm is a fast, scalable alternative to SQLite with mobile to cloud data sync that makes building real-time, reactive mobile apps easy. - Source: dev.to / 8 months ago
  • Looking for android java developer mentor
    I would focus on Kotlin instead of Java, there's really no point in sticking to Java at this point. And when it comes to databases, some local ones that are pretty easy to get into are Realm and ObjectBox, SQLite can definitely be a bit overwhelming at the beginning. Source: 11 months ago
  • Want to build a simple database app....Where do I start
    Just to add to this, there's also Realm and ObjectBox as alternatives. Source: about 1 year ago
  • Firebase vs MongoDB atlas
    There is some crossover between the BaaS of Firebase and what MongoDB Atlas is offering if you are developing using Atlas Sync and Realm. Even so, there is a whole lot more you can find in terms of tutorials and community support for Firebase so it is hard to know how many of the Mongo claims are just future bugs for your project vs what people are currently doing with Firebase.

  • 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 / 3 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 / 22 days 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
  • 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 / 7 months ago
  • What did I do to deserve a JavaScript database?
    For anyone who wants to not only make jokes but actuall learn something, I recommend to start with exploring the github repo: https://github.com/pubkey/rxdb. Source: over 1 year ago
