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.

Developing a web application is a challenging task in itself and making sure that the application follows best practices and is consistent puts additional load on the developer. Angular CLI tries to solve the latter part of these challenges. It's a command-line interface which helps in building, managing, and enforcing the best practices for an Angular application.

  • Predefined best practices
  • Correct naming conventions for our code
  • Optimized build scripts
  • Folder structure
  • Test structure

The Angular team answered and solved these problems by developing Angular CLI.

Apart from Angular CLI, there are many seed projects which can help you get started...
