Guess who's back?
Joel Arvidsson is. And this time he focused his skills into a new set of animations and transitions that can be easily used in a plain and simple declarative - React (Native) friendly - manner.

Want to know what we like most?
That would be working demos. And there's plenty of animated things flying around into the package repository:

react-native-animatable (Example) on GitHub

Standard set of easy to use animations and declarative transitions for React Native

var Animatable = require('react-native-animatable');

React.createClass({
  render: function() {
    return (
      <TouchableWithoutFeedback onPress={() => this.refs.view.bounce(800);}>
        <Animatable.View ref="view">
          <Text>Bounce me!</Text>
        </Animatable.View>
      </TouchableWithoutFeedback>
    );
  }
};
