We'll download the requirements for getting started with React Native, refactor our app to ES6, walk through debugging, and talk about the philosophy behind React and React Native.

Install:

brew install --HEAD watchman

brew install flow

npm install -g react-native-cli

Create a project:

react-native init githubnotepicker

Run the project:

cd githubnotepicker

react-native run-ios

The simulator will pop up.

Enable the hot reload:

cmd + D -->  enable hot reload

After that, once you change the code, the app will reload automatically.

Debugger:

class githubnotetaker extends Component {

  render() {

    name="zhentian";

    debugger;

    return (

      <View style={styles.container}>

        <Text style={styles.welcome}>

          Welcome to React Native!

        </Text>

        <Text style={styles.instructions}>

          To get started, edit index.ios.js

        </Text>

        <Text style={styles.instructions}>

          Press Cmd+R to reload,{'\n'}

          Cmd+D or shake for dev menu

        </Text>

      </View>

    );

  }

}
