Mastering TypeScript 3 - Third Edition

Overview of this book

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. Starting with an introduction to the TypeScript language, before moving on to basic concepts, each section builds on previous knowledge in an incremental and easy-to-understand way. Advanced and powerful language features are all covered, including asynchronous programming techniques, decorators, and generics. This book explores many modern JavaScript and TypeScript frameworks side by side in order for the reader to learn their respective strengths and weaknesses. It will also thoroughly explore unit and integration testing for each framework. Best-of-breed applications utilize well-known design patterns in order to be scalable, maintainable, and testable. This book explores some of these object-oriented techniques and patterns, and shows real-world implementations. By the end of the book, you will have built a comprehensive, end-to-end web application to show how TypeScript language features, design patterns, and industry best practices can be brought together in a real-world scenario.

Using third-party libraries

In this section of the chapter, we will begin to explore some of the older third-party JavaScript libraries, their declaration files, and how to write compatible TypeScript for each of these frameworks. We will compare Backbone, Angular (version 1), and Ext JS, which are all frameworks for building rich client-side JavaScript applications. During our discussion, we will see that some frameworks are highly compliant with the TypeScript language and its features, some are partially compliant, and some have very low compliance.

In the next chapter, we will explore some third-party JavaScript libraries that have been written explicitly with TypeScript in mind, or for which the TypeScript compiler has been modified to work with. In the remainder of this chapter, however, we'll focus on standard third-party libraries that were designed to support JavaScript...
