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.

Application 2 – Trello

It's time for us to shift gear and move on to more complex topics. In the previous chapter, we finished our first application and, in doing so, learned quite a few concepts of TypeScript and Angular. We will continue this practice in this chapter as well. We will start with our second application, Sample Trello board, and during the course of building this application, we'll learn more concepts of TypeScript and Angular.

We will cover the following topics in this chapter:

  • An introduction to the sample Trello application: First off, we will take a brief look at the application we will be building and the feature set it will have.
  • TypeScript namespace and modules: We'll look at how TypeScript provides an opportunity to write modular code with namespaces and modules.
  • TypeScript generics: One of the most powerful features of TypeScript...
