What about PhoneGap? Seems weird to support React Native but not PhoneGap.
- timanglade 11y ago
  Hi, Tim from Realm here. We actually rely on a custom C++ core, which means we have to support each JavaScript engine separately. We completed support for JavaScriptCore first, which React Native uses on both iOS & Android. To support PhoneGap / Cordova we’d need to support V8, which will be close to as much work as supporting JSC in the first place. We’re looking forward to getting it done though! https://github.com/realm/realm-js/issues/261 https://github.com/realm/realm-js/issues/261 Beyond that we were quite excited about the architectural decisions behind React Native and the emerging community around it, so we figured it’d be a good place to start that lined up very well with our own goals!

I think this is a very exciting match for both eco systems. I look forward to seeing where it will go.

can it be used as a simple key/value store?
- patrickrogers 11y ago
  Patrick from Realm here. Realm _can_ be used as a key-value store using our primary keys but at the moment it does expect a fixed schema (all of the keys can be optional though). It’d be trivial for us to relax that requirement and we do have dynamic APIs that allows this on Swift/Objective-C/Java. That said, there’s a lot more Realm can do that a K/V store can’t such as query efficiently on arbitrary properties, link objects in a graph, and more. Does that answer your question?
  - grandalf 11y ago
    Yes -- is there a doc about the graph semantics?
    - timanglade 11y ago
      You can add any object as a property of another object, and access them via dot notation: https://realm.io/docs/react-native/latest/#object-properties https://realm.io/docs/react-native/latest/#object-properties You can probably find some more advanced examples in our Swift docs https://realm.io/docs/swift/latest/#relationships https://realm.io/docs/swift/latest/#relationships We’re barely scratching the surface of this in our query language, which is heavily NSPredicate-inspired, but we might add more OpenCypher-ish features in the future. (And we’d greatly appreciate concrete use-cases or anything else you can share in a GitHub issue to help us prioritize development) https://github.com/realm/realm-js/issues https://github.com/realm/realm-js/issues

        Sounds interesting!

If you are interested in React Native and Couchbase Lite, here's a tutorial for Android [1] and notes for iOS [2] [1] http://blog.couchbase.com/2015/november/getting-started-with-react-native-android-and-couchbase-lite http://blog.couchbase.com/2015/november/getting-started-with...

It's too bad that Realm's core technology isn't open source, it would be interesting to see what other immutable databases (e.g. Datomic) would do with the ideas they've come up with. Also grafting Datascript onto Realm for a datalog competitor to sqlite would be sweet.

Does anyone know the actual queries that are used in the benchmark comparison?

Is this usable with electron / nodewebkit apps ?
- brmunk 11y ago
  Not out of the box at the moment. But it would technically be possible to do. Feel free to post a suggestion to https://github.com/realm/realm-js/issues https://github.com/realm/realm-js/issues so we can see the interest.

Congrats to the team. We've been really happy trying it out. It's a drop-in replacement for the standard flux pattern.

Awesome news, thanks for showing support for RN!
