MDX doc doesn't work with react-native installation

[renanbronchart]

Describe the bug
I followed this doc:
https://storybook.js.org/tutorials/intro-to-storybook/react-native/en/get-started/

But after all configurations, MDX files can't be resolved.
And I have this error on my simulator.

And I can't follow some issues about that because I haven't the same directory generated.
I have /storybook/index.js and not /.storybook/main.js. I don't know why, but that have been generated by the command:
npx -p @storybook/cli sb init --type react_native

To Reproduce
I've followed the react-native doc with storybook, and I've just added a storyloader file.

// storybook/storyLoader.js

// Auto-generated file created by react-native-storybook-loader
// Do not edit.
//
// https://github.com/elderfo/react-native-storybook-loader.git

function loadStories() {
  require('../src/uikit/badge/badge.stories');
}

const stories = ['../src/uikit/badge/badge.stories'];

module.exports = {
  loadStories,
  stories,
};

// storybook/index.js

// if you use expo remove this line
import { AppRegistry } from 'react-native';

import { getStorybookUI, configure, addDecorator } from '@storybook/react-native';
import { withKnobs } from '@storybook/addon-knobs';
import { loadStories } from './storyLoader';

import './rn-addons';

// enables knobs for all stories
addDecorator(withKnobs);

// import stories
configure(() => {
  loadStories();
}, module);

// Refer to https://github.com/storybookjs/react-native/tree/master/app/react-native#getstorybookui-options
// To find allowed options for getStorybookUI
const StorybookUIRoot = getStorybookUI({});

// If you are using React Native vanilla and after installation you don't see your app name here, write it manually.
// If you use Expo you should remove this line.
AppRegistry.registerComponent('%APP_NAME%', () => StorybookUIRoot);

export default StorybookUIRoot;

# Badge

<ArgsTable of={Badge} />

Here the `Badge` component:

<Story name="primary">
  <Badge radius={13} backgroundColor={colors.primary}>
    <Text style={{
      fontSize: 14,
      color: colors.secondary,
      fontWeight: 600
    }}>10</Text>
  </Badge>
</Story>


## Basics usages

<Canvas>
  <Story name="primary">
    <Badge radius={13} backgroundColor={colors.primary}>
      <Text style={{
        fontSize: 14,
        color: colors.secondary,
        fontWeight: 600
      }}>10</Text>
    </Badge>
  </Story>
  <Story name="secondary">
    <Badge radius={24} backgroundColor={colors.secondary}>
      <Text style={{
        fontSize: 18,
        color: colors.primary,
        fontWeight: 600
      }}>50</Text>
    </Badge>
  </Story>
</Canvas>

@renanbronchart I've moved this over to the react native repo since its separate.

MDX is not yet supported in react native so this isn't a bug it's just a missing feature.

However MDX on react native is not necessarily easy. I looked into it once before and I didn't find any well maintained libraries. However its been a while.

If you know of any good way to support MDX in react native I'm open to it.

On another note you can use MDX with addon-react-native-web already so you might be interested in that addon for web storybook.

[dannyhw]

It may be possible to use MDX with storybook via this project from @danieldunderfelt and probably soon I will experiment with it.

https://github.com/danieldunderfelt/rn-mdx

talk about it here:
https://portal.gitnation.org/contents/mdx-in-react-native

I think that you could already get it working in your own project if you are willing to experiment a bit. I'm not sure if it could be made more automatic for storybook however maybe someone has ideas?

[chococrypto]

so, were you able to create the documentation?

[dannyhw]

@di1606 as I mention above it should be possible to do manually but I haven't had time to work on a guide or anything unfortunately
