Exactly, what happens when we "alias" the React Native to Web?
It means the library react-native-web will convert the react-native components into HTML/CSS tags.
Here an example:
<View>
<Text style={{color: 'red'}}>I'm an awesome text</Text>
</View>
Will become into when rendered on browser:
<div>
<span style="color: red">I'm an awesome text</span>
</div>
When working with Expo, why isn't some packages available? For example, the LinearGradient get's an error saying it can't be found.
Expo offers a very simple way to start developing React Native apps. But it's a closed box where you cannot add community native packages, only the native packages that comes with Expo. There is an exception, the js-only packages, like: https://github.com/crazycodeboy/react-native-check-box
For the native packages, you need to link them in the native side of your app and compile it. To achieve this I suggest you to start in the native development, you can found the path here: https://facebook.github.io/react-native/docs/getting-started#the-react-native-cli
I want to use Netlify Identity Widget, but that renders in HTML. How do I use that with React Native Web?
You can use any package/widget/library that renders HTML, because you will run it on browsers. You can start using it just typing yarn add netlify-identity-widget
or npm install netlify-identity-widget --save into your react-native-web root folder.
Hope I helped!
