Overview of this book

The ASP.NET Core 2.0 Framework has been designed to meet all the needs of today’s web developers. It provides better control, support for test-driven development, and cleaner code. Moreover, it’s lightweight and allows you to run apps on Windows, OSX and Linux, making it the most popular web framework with modern day developers. This book takes a unique approach to web development, using real-world examples to guide you through problems with ASP.NET Core 2.0 web applications. It covers Visual Studio 2017- and ASP.NET Core 2.0-specifc changes and provides general MVC development recipes. It explores setting up .NET Core, Visual Studio 2017, Node.js modules, and NuGet. Next, it shows you how to work with Inversion of Control data pattern and caching. We explore everyday ASP.NET Core MVC 2.0 patterns and go beyond it into troubleshooting. Finally, we lead you through migrating, hosting, and deploying your code. By the end of the book, you’ll not only have explored every aspect of ASP.NET Core MVC 2.0, you’ll also have a reference you can keep coming back to whenever you need to get the job done.

RequireJS is a JavaScript file and module loader. We usually use it in browser applications, but it can be used in Node.js applications as well.

The good thing about RequireJS is that it can load files and modules asynchronously. Asynchronous loading makes the web page appear on the screen faster. It basically postpones loading files to whenever they are needed.

By doing asynchronous loading, web pages start with smaller files, and fewer network calls, resulting in quicker startups.

If we're developing a large application and it has tens of JavaScript files, it's hard to maintain dependency and load the right file in the right place, for example, in e-commerce applications such as the ones we have; the shoppingCart.js, product.js, and customer.js files.

In the main.js file, if we're calling the purchase() method from the shoppingCart.js file, it requires a method...
