1. clone the project
a run below command from root of project folder
b sbt clean compile fastOptJS::webpack
c above command creats a target /AndroidApp/target/scala-2.12/scalajs-bundler/main
 copy above buindel and launcher.js files in to root project folder under js folder
d sudo npm install -g webpack@

2. In the project directory run:
a  in root project loaction edit index.html file with notepad and edit js script tags to
b`sbt ~fastOptJS`

3. On your browser go to:
a. http://localhost:12345/index.html
b. Note http://127.0.0.1:12345/ will not work only above one will work

if facing issue with npm 6.0.0, update it using below:-
sudo npm i npm@next -g

To get set up with the basic project structure for a native module we will use a third party tool react-native-create-library. You can go ahead further and dive deep into how that library works, for our needs we will just need:

$ npm install -g react-native-create-library
$ react-native-create-library MyLibrary

Where MyLibrary is the name you would like for the new module. After doing this you will navigate into MyLibrary folder and install the npm package to be locally available for your computer by doing:

$ npm install

After this is done you can go to your main react app folder (which you created by doing react-native init MyApp)

    add your newly created module as a dependency in your package.json
    run npm install to bring it along from your local npm repository.

Assuming that you have Node installed, you can use npm to install the create-react-native-app command line utility:

npm install -g create-react-native-app

Then run the following commands to create a new React Native project called "AwesomeProject":

create-react-native-app AwesomeProject

cd AwesomeProject
npm start

This will start a development server for you.

Running your app on a simulator or virtual device

Create React Native App makes it really easy to run your React Native app on a physical device without setting up a development environment. If you want to run your app on the iOS Simulator or an Android Virtual Device, please refer to the instructions for building projects with native code to learn how to install Xcode and set up your Android development environment.

Once you've set these up, you can launch your app on an Android Virtual Device by running npm run android, or on the iOS Simulator by running npm run ios (macOS only).

Success! Created AwesomeProject at /home/ashutosh/Development/AwesomeProject
Inside that directory, you can run several commands:

  npm start
    Starts the development server so you can open your app in the Expo
    app on your phone.

  npm run ios
    (Mac only, requires Xcode)
    Starts the development server and loads your app in an iOS simulator.

  npm run android
    (Requires Android build tools)
    Starts the development server and loads your app on a connected Android
    device or emulator.


  npm test
    Starts the test runner.

  npm run eject
    Removes this tool and copies build dependencies, configuration files
    and scripts into the app directory. If you do this, you can’t go back!


We suggest that you begin by typing:

  cd AwesomeProject
  npm start

Happy hacking!
