Share components between your React Native mobile app and your Gatsby static website.

1. Install the plugin: yarn add react-native-web gatsby-plugin-react-native-web or npm install --save react-native-web gatsby-plugin-react-native-web

2. Create a gatsby-config.js and use the plugin: gatsby-config.js

   module.exports = {
     plugins: [
       `gatsby-plugin-react-native-web`,
       /* ... */
     ],
   }

3. Install the babel preset for React Native web: yarn add --dev babel-preset-expo or npm install --save-dev babel-preset-expo

4. Create a babel.config.js and use the Babel preset: babel.config.js

   module.exports = { presets: ['babel-preset-expo'] }

Use the 2.x branch

yarn add [email protected]

Add the RN / RNW dependencies. Choose versions carefully according to RNW doc. If you want you can pick versions from examples folder.

Please report here if it works fine for you, or not.

The examples folder have runnable Gatsby site demos. They are also hosted:

• Todos example: a "todo backoffice" built with Gatsby + RNW + Apollo + TS + react-native-paper: a fancy but effective stack.

You'd better look at the code of the online demo.

Otherwise, here is a simple Gatsby page that renders fine:

import React from 'react'
import Link from 'gatsby-link'
import { StyleSheet, TouchableOpacity, Text, View } from 'react-native'

const styles = StyleSheet.create({
  box: { padding: 10, margin: 10, borderWidth: 1, borderColor: 'black' },
  text: { fontWeight: 'bold', color: 'red' },
  button: {
    marginVertical: 40,
    paddingVertical: 20,
    paddingHorizontal: 10,
    borderWidth: 1,
    borderColor: 'black',
    backgroundColor: 'lightgrey',
    alignItems: 'center',
  },
  buttonText: { fontWeight: 'bold', color: 'black' },
})

const IndexPage = () => (
  <View style={styles.box}>
    <Text style={styles.text}>
      Hi this is React-Native-Web rendered by Gatsby
    </Text>
    <TouchableOpacity style={styles.button} onPress={() => alert('it works')}>
      <Text style={styles.buttonText}>Button</Text>
    </TouchableOpacity>
    <Link to="/page-2/">Go to page 2</Link>
  </View>
)

export default IndexPage
