Overview of this book

TypeScript is the future of JavaScript. Having been designed for the development of large applications, it is now being widely incorporated in cutting-edge projects such as Angular 2. Adopting TypeScript results in more robust software - software that is more scalable and performant. It's scale and performance that lies at the heart of every project that features in this book. The lessons learned throughout this book will arm you with everything you need to build some truly amazing projects. You'll build a complete single page app with Angular 2, create a neat mobile app using NativeScript, and even build a Pac Man game with TypeScript. As if fun wasn't enough, you'll also find out how to migrate your legacy codebase from JavaScript to TypeScript. This book isn't just for developers who want to learn - it's for developers who want to develop. So dive in and get started on these TypeScript projects.

Preface

Chapter 2. A Weather Forecast Widget with Angular 2

In this chapter, we'll create a simple application that shows us the weather forecast. The framework we use, Angular 2, is a new framework written by Google in TypeScript. The application will show the weather of the current day and the next. In the following screenshot, you can see the result. We will explore some key concepts of Angular, such as data binding and directives.

We will build the application in the following steps:

  • Using modules

  • Setting up the project

  • Creating the first component

  • Adding conditions to the template

  • Showing a forecast

  • Creating the forecast components

  • The main component
