Advanced TypeScript Programming Projects

Overview of this book

With the demand for ever more complex websites, the need to write robust, standard-compliant JavaScript has never been greater. TypeScript is modern JavaScript with the support of a first-class type system, which makes it simpler to write complex web systems. With this book, you’ll explore core concepts and learn by building a series of websites and TypeScript apps. You’ll start with an introduction to TypeScript features that are often overlooked in other books, before moving on to creating a simple markdown parser. You’ll then explore React and get up to speed with creating a client-side contacts manager. Next, the book will help you discover the Angular framework and use the MEAN stack to create a photo gallery. Later sections will assist you in creating a GraphQL Angular Todo app and then writing a Socket.IO chatroom. The book will also lead you through developing your final Angular project which is a mapping app. As you progress, you’ll gain insights into React with Docker and microservices. You’ll even focus on how to build an image classification program with machine learning using TensorFlow. Finally, you’ll learn to combine TypeScript and C# to create an ASP.NET Core-based music library app. By the end of this book, you’ll be able to confidently use TypeScript 3.0 and different JavaScript frameworks to build high-quality apps.

  1. JavaScript and C# both trace their syntax roots back to C, so they largely follow similar language paradigms such as using { } to denote the scope of an operation. Since all JavaScript is valid TypeScript, this means that TypeScript has exactly the same style here.
  2. The method that starts our program is the static Main method. It looks like this:
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
}
  1. ASP.NET Core uses a rewritten .NET version that removes the constraint that it can only run on the Windows platform. This means that the reach of ASP.NET has greatly increased because it can now run on Linux platforms, as well as on Windows.
  2. Discog limits the number of requests that can be issued from a single IP. For authenticated requests, Discog limits the rate of requests to 60 per minute. For unauthenticated requests, for most cases,...
