Overview of this book

The TypeScript language, compiler, and open source development toolset brings JavaScript development up to the enterprise level. It allows you to use ES5, ES6, and ES7 JavaScript language features today, including classes, interfaces, generics, modules, and more. Its simple typing syntax enables building large, robust applications using object-oriented techniques and industry-standard design principles. This book aims at teaching you how to get up and running with TypeScript development in the most practical way possible. Taking you through two exciting projects built from scratch, you will learn the basics of TypeScript, before progressing to functions, generics, promises, and callbacks. Then, you’ll get to implement object-oriented programming as well as optimize your applications with effective memory management. You’ll also learn to test and secure your applications, before deploying them. Starting with a basic SPA built using Angular, you will progress on to building, maybe, a Chat application or a cool application. You’ll also learn how to use NativeScript to build a cool mobile application. Each of these applications with be explained in detail, allowing you to grasp the concepts fast. By the end of this book, you will have not only built two amazing projects but you will also have the skills necessary to take your development to the next level.

What this book covers

Chapter 1, Getting Started with TypeScript, provides us with an introduction to TypeScript and its features. We will create a small ToDo application, which provides insights into basic TypeScript features.

Chapter 2, Our First Application – Sports News Combinator, introduces us to the basic concepts of TypeScript and Angular. We'll take a look at types in TypeScript and how to set up an Angular application, along with the concept of components.

Chapter 3, Sports News Combinator – Adding Features, covers important concepts of TypeScript, such as interfaces, classes, and object-oriented programming. In Angular, we look at data binding, directives, and templates.

Chapter 4, Sports News Combinator – the Final Version, adds final features to the application and, in doing so, covers decorators, dependency injection, routing, and HTTP using RxJS observables in Angular.

Chapter 5, Application 2 – Trello, is our second application. With this application, we'll look at generics, namespaces, and modules in TypeScript. We'll also look at some of the advanced features of Angular, such as communication between components and life cycle hooks.

Chapter 6, Trello – Adding Features, takes us deeper into the feature set of TypeScript and Angular. We cover iterators and async programming using callbacks, promises, and observables. In Angular, we'll look at pipes and dependency injection.

Chapter 7, Testing the Trello Application, introduces us to the testing features provided in Angular. We look at the unit testing of services, pipes, and components.

Chapter 8, Trello – Using Angular CLI, provides us with the details of the Angular CLI and its feature set. We look at creating new applications, generating components, services, pipes, classes, and interfaces. Then, we shift our focus to features such as building, serving, and linting any Angular-based web application.

Chapter 9, Trello Mobile – Using NativeScript, allows us to convert our web application into a native mobile application. In this chapter, we will look at the NativeScript framework and see how we can use its features to create Android and iOS applications from our web application.

Chapter 10, Deploying Sample Trello on the Cloud Using Microsoft Azure, explains cloud as our deployment platform. We will look at Azure as Platform as a Service and deploy our application using FTP and GitHub. We will also look at how Azure enables us to perform continuous deployment for our application.
