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 explored some of the fundamental building blocks in application development. We started out by building an Express server that was capable of serving our Angular application, and then explored how we can set and use configuration variables and server logging to build a production-ready Express server. We then explored the use of Brackets and Emmet to help in the rapid design of mockup web pages.

The bulk of this chapter, however, has focused on authentication. We explored the use of Angular routing and Auth Guards to define a secure section of the application that is only available to logged-in users of the system. We then worked through how to send POST and GET requests to a REST endpoint through the use of the HttpClient and Express routing. To secure our application correctly, we then implemented the generation and verification of JWT tokens...
