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.

SystemJS module loading

SystemJS is a module loader that understands both CommonJS module format, AMD module format, and even the new ES6 module format. It works in both Node and the browser, and as such, describes itself as a universal module loader. Before SystemJS came along, Node-based solutions used CommonJS format, and browser-based solutions used AMD format. Now we can use CommonJS format in the browser, and even mix and match module syntax. In this section, we will take a look at how to configure SystemJS for loading CommonJS modules in the browser.

SystemJS installation

SystemJS can be installed using npm as follows:

npm install systemjs --save 

The relevant declaration files can be installed using @types as follows...
