Mastering TypeScript 3 - Third Edition

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 and Angular integration

The default setup for an Angular application configured using the Angular CLI already contains a number of options that can be used in a production setting. One of these options is the outputPath property, which specifies where compiled JavaScript files are written to. By using a separate path for output files, we know that we can distribute the contents of this directory as a fully working version of our site.

The outputPath option can be found in the angular.json file, under the Projects | Angular-sample | Architect | Build | Options configuration section. This property is, by default, set to "dist/angular-sample", and therefore, when we issue an ng build command, we will notice that the Angular CLI will generate a number of files in this directory. These include main.js, polyfill.js, runtime.js, styles.js, and vendor.js. These JavaScript...
