I started programming in React Native, and I got used to use the syntax:

async myFunction(){ ... return await otherFunction();
}

But I don't know how to make it compatible with React JS and React Native in a shared package. How can I accomplish this so that it works in both platforms?

Thanks!

If you building using create-react-app it's been available since v0.2.3

It can be used inside a Component like this

class App extends Component { constructor(props) { super(props); this.state = { message: '' }; } async componentDidMount() { this.setState({ message: 'loading...' }); let d = await getData('/posts/1'); this.setState({ message: d }); } render() { let { message } = this.state; return ( <div className="App"> <p className="App-intro"> { message } </p> </div> ); }
}

React Native ships with Babel and some Babel presets, whereas React on the web is just React related code.

If you want to use async/await on the web today you'll need Babel and the correct transforms:

or the stage-1 presets, which is fairly common in React apps today.

Alternatively you can use Typescript.

Since version 2.1 it is possible to use async/await and directly transpile to ES5 (in other words have it run on ~all browsers)
