Adding Expo to an existing react-native project

Created a simple React Native example following this tutorial.

$ npm i -D react react-native
+ react@17.02
+ react-native@0.64.2

Then added Expo using the doc

$ npm i -D expo react-native-web react-dom
+ react-dom@17.0.2
+ expo@41.0.1
+ react-native-web@0.17.0

Remove the main and add a shortcut to run Expo

{
  "scripts": {
    "start": "react-native start",
    "web": "expo start --web"
  },
  "devDependencies": {
    "expo": "^41.0.1",
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-native": "^0.64.2",
    "react-native-web": "^0.17.0"
  }
}

Execute npm run web and the app should run at localhost:19006
