Summary: JSTester is missing a page for the Dimensions API. This also makes it hard to test out some things in the tester app that affect the app's frame when you need to know how they affect the dimensions. ![screenshot_1508500992](https://user-images.githubusercontent.com/53399/31820157-d28dc1cc-b554-11e7-84a1-4bb39204adab.png) ![simulator screen shot - iphone 7 plus - 2017-10-20 at 05 03 08](https://user-images.githubusercontent.com/53399/31820158-d2a52204-b554-11e7-9eb4-84c757830871.png) * [INTERNAL] [ENHANCEMENT] [JSTester] - Dimensions example added to JSTester Closes https://github.com/facebook/react-native/pull/16473 Differential Revision: D6117984 Pulled By: hramos fbshipit-source-id: 8f42ca7aaf42b76f8b9771317ce82a2cfce47ffa
RNTester
The RNTester 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
RNTester/RNTester.xcodeproj
in 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 :RNTester:android:app:installDebug
./scripts/packager.sh
Note: Building for the first time can take a while.
Open the RNTester 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 rntester
buck install -r rntester
./scripts/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).
