Counter application from

Setting up the counter application

  1. Unzip the counter application example in
  2. Then, run the following command to install all dependencies:
npm install
  1. Afterward, we can start the application using the following command:
npm start

This will start the webpack-dev-server on http://localhost:8080.

  1. Open http://localhost:8080/ in your browser, and you should see the application from the screenshot given in the preceding section.
