The Ionic platform is a popular hybrid application framework for building mobile applications using web technologies you're probably already familiar with. In this course, learn how to build a mobile app using Ionic 2, the latest version of the platform. To begin, learn what Ionic actually is and how to install the all-important command-line interface (CLI). Next, learn how to use the Ionic CLI to create a project—an app that allows users to share text posts and view them in a feed—and add components to that project. Discover how to use Firebase as a serverless back end for a database, and establish a connection between your app and the Firebase database using the AngularFire2 library.
