Learning TypeScript 2.x - Second Edition

By: Remo H. Jansen

Overview of this book

TypeScript is an open source and cross-platform statically typed superset of JavaScript that compiles to plain JavaScript and runs in any browser or host. This book is a step-by-step guide that will take you through the use and benefits of TypeScript with the help of practical examples. You will start off by understanding the basics as well as the new features of TypeScript 2.x. Then, you will learn how to work with functions and asynchronous programming APIs. You will continue by learning how to resolve runtime issues and how to implement TypeScript applications using the Object-oriented programming (OOP) and functional programming (FP) paradigms. Later, you will automate your development workflow with the help of tools such as Webpack. Towards the end of this book, you will delve into some real-world scenarios by implementing some full-stack TypeScript applications with Node.js, React and Angular as well as how to optimize and test them. Finally, you will be introduced to the internal APIs of the TypeScript compiler, and you will learn how to create custom code analysis tools.

Working with the TypeScript Compiler and the Language Services

In this chapter, we are going to learn about the internals of the TypeScript compiler and the TypeScript language services.

These topics may seem very advanced and not something that everybody will find useful. While it is true that it is a topic for advanced users, the truth is that everybody can benefit from understanding the TypeScript language services. Understanding the compiler API of the TypeScript compiler can help us to develop many kinds of development tools and to automate certain aspects of our development workflow.

The goal of this chapter is not to make you an expert in the compiler's internals or the development of TypeScript tools, but to gently introduce you to this very extensive topic. In this chapter, we will cover the following topics:

  • The internal architecture of the TypeScript compiler
  • ...
