Introducing Ionic 2 [Video]

Overview of this book

This course delivers an (early) introduction to Ionic 2, and demonstrates all of the core elements of the framework by developing a single project throughout the runtime. The course dives into starting up an Ionic 2 project, using the menu application type as the template for the project. It introduces the component-based structure of Ionic 2 applications, develops navigation functionality and introduces TypeScript for development. Moving in sequence from there the course then demonstrates how to leverage Ionic for views and Angular 2 for the logic, utilizing bult-in Angular2 and Ionic2 directives to display content and implementing 2 way data binding. Services, observables and dependency injection are treated, and the second half of the course starts to dive into deeper, advanced topics creating custom components, binding attributes and listening to events via directives. Working with pipes for data filtering and rendering, using built-in Ionic 2 components, and implementing effective data persistence using the native interface.

Building a Form
Forms are one of the most common type of interaction with users. They can be tedious to build and validate, though. We will use the FormBuilder service to create a form focused on its inputs and leverage the validation framework to display error messages when needed. - Build a form using form builder - Create the corresponding bindings in the template: ngFormModel, ngControl - Validate the form easily using various Booleans on controls: valid, invalid, pristine, untouched, and so on
