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.

A modern development workflow

Developing a web application with high-quality standards has become a time-consuming activity. If we want to achieve a great user experience, we will need to ensure that our applications can run as smoothly as possible on many different web browsers, devices, internet connection speeds, and screen resolutions. Furthermore, we will need to spend a lot of our time working on quality assurance and performance optimization tasks.

As software engineers, we should try to minimize the time we spend on trivial and repetitive tasks. This might sound familiar as we have been doing this for years. We started by writing build scripts (such as makefiles) or automated tests and today, in a modern web development workflow, we use many tools to literally try to automate as many tasks as we can. These tools can be categorized into the following groups:

  • Source control...
