First Install npm modules in the root module:
Make sure, you are using NPM3.
cd ../
npm install
cd ./example
Then install NPM modules for this example app:
npm install
Run the app with npm start
. Then you'll be able to a cess the app via http://localhost:9999.
Once you made a change to the example app or in the root module, the client app will reload again.
This reload is a full reload but not HMR based hot reloading.
