JavaScript for .NET Developers

Overview of this book

If you want to improve responsiveness or the UX in your ASP.NET applications, JavaScript can be a life saver. In an age where server-side operations have shifted to the client, being able to handle JavaScript with confidence and fluency is vital for ASP.NET developers. There’s no point trying to fight it, so start learning with this book. Make sure your projects exceed user expectations. Begin by getting stuck into the basics of JavaScript, and explore the language in the context of ASP.NET Core. You’ll then find out how to put the principles into practice, as you learn how to develop a basic ASP.NET application using Angular 2 and TypeScript. You’ll also develop essential skills required to develop responsive apps, with a little help from AJAX, ensuring that you’re building projects that can be easily accessed across different devices. With guidance on Node.js and some neat techniques to test and debug a range of JavaScript libraries in Visual Studio, you’ll soon be well on your way to combining JavaScript with ASP.NET in a way that’s capable of meeting the challenges of modern web development head-on.

Structural patterns


Structural patterns are used to simplify the relationships between objects. In the following sections, we will discuss all four structural patterns mentioned previously, and how to implement them in JavaScript.

Adapter pattern

The adapter pattern is used in situations in which our application is dependent on any object whose properties and methods change frequently and we want to avoid modifying the code to use them. The adapter pattern allows us to wrap the interface of a specific object as what the client expects and rather than changing the whole implementation we can just call the wrapper object which contains the code as per the modified version. This wrapper object is called an adapter. Let's have a look at a basic example that uses the PersonRepository to save the person object by performing an Ajax request:

The following is the old interface of the PersonRepository object:

// old interface
    function PersonRepository(){
        this.SavePerson= function(name, email...
