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.

Summary

In this chapter, we have had a look at using modules, both CommonJS and AMD. We explored the syntax used for modularization, and showed how to both export and import modules. We then explored the use of AMD module syntax using the Require library, and discussed how to take care of module dependencies. We then explored the use of CommonJS module syntax, and showed the equivalent structure for module dependencies using SystemJS. Our journey continued with an in-depth discussion on Node and Express modules, where we put together a sample application to render both an index and a login page, and handle logins through session information. We then discussed how to set up and use a cloud-based execution environment for our code without the need for a server at all, as well as covering Amazon Web Services and AWS Lambda functions.

In the next chapter, we will tackle object-oriented...
