Summary: For navigation actions at high level, reducers from NavigationReducers does not know anything about the app-specific state thus people won't use these reducers. Instead, people should build their own reducers. There are a lot of good libraries available that help people to reducing things if that's what they really need. At the low level, for navigation state changes that don't involve app-specific state, `NavigationStateUtils` should server that kind of need. `NavigationReducers` serves little benefit cause it does not know the app state, it does not know how to traverse the navigation states which can be a tree, a list or a map. That said, we hold no interest in owning in the core navigation library. Reviewed By: ericvicenti Differential Revision: D3372910 fbshipit-source-id: 797382b46e7d64b7ad578b51dd37e2b941faa83d
UIExplorer
The UIExplorer is a sample app that showcases React Native views and modules.
Running this app
Before running the app, make sure you ran:
git clone https://github.com/facebook/react-native.git
cd react-native
npm install
Running on iOS
Mac OS and Xcode are required.
- Open
Examples/UIExplorer/UIExplorer.xcodeprojin Xcode - Hit the Run button
See Running on device if you want to use a physical device.
Running on Android
You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.
Start an Android emulator (Genymotion is recommended).
cd react-native
./gradlew :Examples:UIExplorer:android:app:installDebug
./packager/packager.sh
Note: Building for the first time can take a while.
Open the UIExplorer app in your emulator.
See Running on Device in case you want to use a physical device.
Running with Buck
Follow the same setup as running with gradle.
Install Buck from here.
Run the following commands from the react-native folder:
./gradlew :ReactAndroid:packageReactNdkLibsForBuck
buck fetch uiexplorer
buck install -r uiexplorer
./packager/packager.sh
Note: The native libs are still built using gradle. Full build with buck is coming soon(tm).
Built from source
Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.
This is different from apps created using react-native init which have a dependency on a specific version of React Native JS and native code, declared in a package.json file (and build.gradle for Android apps).
