+# examples
+
+These examples are a clone of React Native's
+[RNTester](https://github.com/facebook/react-native/tree/v0.55.4/RNTester).
+RNTester showcases React Native views and modules. It's used to manually verify
+the appearance and behavior of React Native for Web.
+
+Try the [examples app](https://necolas.github.io/react-native-web/examples) online.
+
+To run the examples locally:
+
+```
+yarn examples
+open ./packages/examples/dist/index.html
+```
+
+Develop against these examples:
+
+```
+yarn compile --watch
+NODE_ENV=development yarn examples --watch
+```
+
+## Notes
+
+The RNTester examples rely on features specific to [React Native's
+packager](https://github.com/facebook/metro) such as loading resolution
+variants of images, Babel transforms, compiling ES module dependencies, and
+Haste – Facebook's module system. These features are *emulated* in this
+package's `webpack.config.js`.
+
+The commonjs export in `react-native-web` is also used to ensure that webpack
+can load the aliased modules correctly (as compiled ES modules are only
+available from the `.default` property of a module.)

+# React Native: Animated
+
+ReactEurope 2015, Paris - Spencer Ahrens - Facebook
+
+<br /><br />
+
+## Fluid Interactions
+
+- People expect smooth, delightful experiences
+- Complex interactions are hard
+- Common patterns can be optimized
+
+<br /><br />
+
+
+## Declarative Interactions
+
+- Wire up inputs (events) to outputs (props) + transforms (springs, easing, etc.)
+- Arbitrary code can define/update this config
+- Config can be serialized -> native/main thread
+- No refs or lifecycle to worry about
+
+<br /><br />
+
+
+## var { Animated } = require('react-native');
+
+- New library soon to be released for React Native
+- 100% JS implementation -> X-Platform
+- Per-platform native optimizations planned
+- This talk -> usage examples, not implementation
+
+<br /><br />
+
+
+## Gratuitous Animation Demo App
+
+- Layout uses `flexWrap: 'wrap'`
+- longPress -> drag to reorder
+- Tap to open example sets
+
+<br /><br />
+
+## Gratuitous Animation Codez
+
+- Step 1: 2D tracking pan gesture
+- Step 2: Simple pop-out spring on select
+- Step 3: Animate grid reordering with `LayoutAnimation`
+- Step 4: Opening animation
+
+<br /><br />
+
+## Animation Example Set
+
+- `Animated.Value` `this.props.open` passed in from parent
+- `interpolate` works with string "shapes," e.g. `'rgb(0, 0, 255)'`, `'45deg'`
+- Examples easily composed as separate components
+- Dismissing tracks interpolated gesture
+- Custom release logic
+
+<br /><br />
+
+
+## Tilting Photo
+
+- Pan -> translateX * 2, rotate, opacity (via tracking)
+- Gesture release triggers separate animations
+- `addListener` for async, arbitrary logic on animation progress
+- `interpolate` easily creates parallax and other effects
+
+<br /><br />
+
+## Bobbles
+
+- Static positions defined
+- Listens to events to maybe change selection
+ - Springs previous selection back
+ - New selection tracks selector
+- `getTranslateTransform` adds convenience
+
+<br /><br />
+
+## Chained
+
+- Classic "Chat Heads" animation
+- Each sticker tracks the one before it with a soft spring
+- `decay` maintains gesture velocity, followed by `spring` to home
+- `stopAnimation` provides the last value for `setOffset`
+
+<br /><br />
+
+## Scrolling
+
+- `Animated.event` can track all sorts of stuff
+- Multi-part ranges and extrapolation options
+- Transforms decompose into ordered components
+
+<br /><br />
+
+# React Native: Animated
+
+- Landing soon in master (days)
+- GitHub: @vjeux, @sahrens
+- Questions?
+
+<br />
