Peter Salanki 52d8851fc8 Cache policy control for image source Summary: In the context of an app an image exists in three resolutions on the server: `thumb` (30px) `feed` (300px) `full` (900px). When looking at an individual item a user can come either from the feed, via a permalink or from other parts of the app. This allows a situation where the `feed` image might or might not already be loaded somewhere in the app. In the detail view I want to render `thumb` with a blur (to quickly display something), then the `feed` image if it exists to have something decent to display until `full` loads. However it is quite a waste to load the `feed` image if it isn't already in cache, and will slow down the time until `full` is loaded. It is possible to track the navigation from feed->detail and that the `feed` image has actually completed loading by the feed component however as component hierarchies grow this turns into quite a lot of prop passing and bad separation of concerns.

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.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 :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).
