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.
