Ionic apps are created and developed primarily through the Ionic command line utility (the “CLI”), and use Cordova to build/deploy as a native app. This means we need to install a few utilities to get developing. Check the official installation process.
You will need to:
Install the template dependencies. After you have Ionic and Cordova installed, you have to install all the dependencies required by the app. To do this just run this command using a terminal inside your ionic app folder path.
$ npm install
Now we have everything installed, we can test our Ionic App.
Check these developer tips to learn how to test your Ionic app like a Native app on iOS and Android devices or emulators.
