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.

Building Applications

Thus far, we have explored the various tools and techniques that we need to use in order to build an application using some of the most popular TypeScript frameworks. We have focused on building an Angular site with a rather complex screen flow, and learned how we can use the State and Mediator design patterns to handle this complexity in a modular way. We have also explored the use of Node and Express that allow us to build a server-side application to handle page generation, and route handling. In the first section of this chapter, we combine the two, and explore how to serve an Angular website from a Node Express server. We will build upon the Angular application that we built in Chapter 11, Object-Oriented Programming, and use it as the basis for further development.

Once we have Express serving our Angular application, we can then explore a number of...
