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.

In this chapter, we have had a look at third-party JavaScript libraries and how they can be used within a TypeScript application. We started by looking at the various ways of including community-released versions of TypeScript declaration files within our projects by using package managers such as NuGet and npm. We then looked at three types of third-party libraries, and discussed how to integrate these libraries with TypeScript. We explored Backbone, which can be categorized as a highly compliant third-party library; Angular 1, which is a partially compliant library; and ExtJS, which is a minimally compliant library. We saw how various features of the TypeScript language can co-exist with these libraries, and showed what TypeScript equivalent code would look like in each of these cases. In the next chapter, we will look at TypeScript specific third-party libraries, which...
