Ionic is an open-source SDK that allows developers to build hybrid mobile apps using HTML, CSS and JavaScript. Ionic is based on AngularJS and uses Cordova to access native device features from a web view. Ionic 2 improves on Ionic 1 by being based on Angular 2 and aiming for the latest mobile platforms and performance. For new projects, Ionic 1 is no longer recommended over Ionic 2 which is currently in beta. The presentation provides an overview of the Ionic ecosystem and demonstrates building a sample app.
