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.

Node has been rather a game changer in the web application world. One of the reasons for this is the lightweight hardware specifications that are needed to run a Node web server. Node applications can be run on pretty much any hardware, starting from something as small as a Rasberry Pi. This means that the cost of setting up a Node web server is dramatically reduced compared to the cost of a server that runs a .NET or Java web application. In the modern age of cloud computing, this means that a small, low-cost cloud server can easily be used to host a Node application.

Most cloud services, including Azure, Amazon and Google, have taken this concept a step further, and now offer the ability to run code without the need for a server at all. This means that we are provided with a runtime environment that has all of the dependencies we need in order to respond...
