Mastering TypeScript: Build enterprise-ready, modular web applications using TypeScript 4 and modern frameworks

Master the TypeScript language and its latest features, explore modern web application frameworks, and build modular systems using industry standard architectural principles and design patterns.

Key Features

• Explore TypeScript 4's key elements and advanced language features
• Use TypeScript with modern frameworks such as Angular, Vue, React, RxJS and Node
• Understand TDD, serverless techniques, micro frontends, and other industry-standard best practices to create high-quality and modular apps

Book Description

TypeScript is both a language and a set of tools to generate JavaScript. It was designed by Anders Hejlsberg at Microsoft to help developers write enterprise-scale JavaScript.

Using a fast-paced, but easy-to-follow set of code samples, this fourth edition will get you up and running with Typescript quickly, introduce core concepts, and then build on this knowledge to help you understand and then apply more advanced language features.

Mastering TypeScript, Fourth Edition also covers a variety of modern JavaScript and TypeScript frameworks and compares their respective strengths and weaknesses. As you advance through this TypeScript book, you'll explore Angular, React, Vue, RxJs, Express, NodeJS, and others. You'll get up to speed with unit and integration testing, data transformation, serverless technologies, and asynchronous programming. You'll also learn how to integrate with existing JavaScript libraries, control your compiler options, and use decorators and generics.

By the end of the book, you will have built a comprehensive set of web applications using Angular, React, and Vue, having integrated them into a single cohesive website, using micro front-end techniques. Mastering TypeScript, Fourth Edition is about learning the language, understanding when to apply its features, and then selecting the framework that is the perfect fit for your real-world project.

What you will learn

• Gain insights into core and advanced TypeScript language features
• Integrate with existing JavaScript libraries and third-party frameworks
• Build full working applications using JavaScript frameworks, such as Angular, React, Vue, and more
• Create test suites for your application with Jest and Selenium
• Apply industry-standard design patterns to build modular code
• Develop web server solutions using NodeJS and Express
• Design and implement serverless API solutions
• Explore micro front-end technologies and techniques

Who this book is for

This book serves as a guide for beginners, as well as providing practical insights and techniques for experienced JavaScript and TypeScript programmers. No prior knowledge of JavaScript is required.

Nathan Rozentals has been writing commercial software for over 30 years, in C, C++, Java and C#. He picked up TypeScript within a week after its initial release in October 2012 and realized how much TypeScript could help when writing JavaScript. He was one of the first people to start blogging about TypeScript, discussing early frameworks such as Backbone, Marionette, ExtJS and AngularJs. He knew he'd hit the mark when Microsoft staff started to reference his blog posts in their CodePlex discussion forums.

Nathan’s TypeScript solutions now control User Interfaces in IoT devices, run as stand-alone applications for Point-of-Sale solutions, provide complex application configuration web sites, and are used for mission-critical server APIs.
