Overview of this book

Writing clean, object-oriented code in JavaScript gets trickier and complex as the size of the project grows. This is where Typescript comes into the picture; it lets you write pure object-oriented code with ease, giving it the upper hand over JavaScript. This book introduces you to basic TypeScript concepts by gradually modifying standard JavaScript code, which makes learning TypeScript easy for C# ASP.NET developers. As you progress through the chapters, you'll cover object programming concepts, such as classes, interfaces, and generics, and understand how they are related to, and similar in, both ES6 and C#. You will also learn how to use bundlers like WebPack to package your code and other resources. The book explains all concepts using practical examples of ASP.NET Core projects, and reusable TypeScript libraries. Finally, you'll explore the features that TypeScript inherits from either ES6 or C#, or both of them, such as Symbols, Iterables, Promises, and Decorators. By the end of the book, you'll be able to apply all TypeScript concepts to understand the Angular framework better, and you'll have become comfortable with the way in which modules, components, and services are defined and used in Angular. You'll also have gained a good understanding of all the features included in the Angular/ASP.NET Core Visual Studio project template.

Production and development configurations

In the DOMManipulation project used throughout this chapter, webpack.config.js specifies a development profile through the mode: "development" setting, while the library bundle is built with a production profile since webpack.config.vendor.js specifies no mode setting. As a consequence, just the library bundle is minimized, while all other chunks and bundles are not minimized. Information about the profile may be passed either through WebPack middleware or as a WebPack parameter. In turn, the WebPack command may be invoked with the desired parameter when the Visual Studio project is published by hooking the publish event within the .csproj Visual Studio project file.

Let's use the DOMMAnipulation project we've been using. As a first step, let's modify webpack.config.js. Find the following code:
