We will start by going to the official Node.js website and download the corresponding binary to our operating system. Git should be installed as well.

To verify the installation, open a new command line window and run:

node --version
npm --version
git --version

Install Ionic CLI:

npm install -g @ionic/cli

Once installation is finished, go to the app folder and install the app dependencies:

ionshop-x.x.x/app:$ npm install

Run app:

ionic serve

Within a few seconds the app should be up and running in your web browser.

For more details the official Ionic guide has all the necessary documentation.
