Currently we only support React Native (both iOS & Android) but we are considering adding support for Cordova/PhoneGap/Ionic as well as Node.js (V8) soon.
* **Mobile-first:** Realm is the first database built from the ground up to run directly inside phones, tablets and wearables.
* **Simple:** Data is directly [exposed as objects](https://realm.io/docs/react-native/latest/#models) and [queryable by code](https://realm.io/docs/react-native/latest/#queries), removing the need for ORM's riddled with performance & maintenance issues.

In case you don't want to use the precompiled version on npm, you can build Realm JS yourself from source. You’ll need an Internet connection the first time you build in order to download the core library.
Prerequisites:
- Node 4.0+
- Xcode 7.2+
- Android SDK 23+
- Android NDK 10e+
`git clone https://github.com/realm/realm-js.git`
In the cloned directory:
`git submodule update --init --recursive`
To build for iOS:
- Open `RealmJS.xcodeproj`
- Select `RealmReact.framework` as the build target
- Build
To build for Android:
-`cd react-native/android`
-`./gradlew publishAndroid`
- The compiled version of the Android module is here: `<project-root>/android`
The underlying core is available under the [Realm Core Binary License](https://github.com/realm/realm-cocoa/blob/master/LICENSE#L210-L243) while we [work to open-source it under the Apache 2.0 license](https://realm.io/docs/react-native/latest/#faq).
