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.

Introducing ASP.NET Core MVC

Microsoft has a long and relatively chequered history with web frameworks. I first started developing server-based applications back in the late 1990s with their Active Server Pages technology, now known as classic ASP. This technology allowed the developer to create dynamic web pages based on user requests and send the resulting web pages back to the client. This technology required a special Internet Information Services (IIS) plugin for it to work, so it was entirely Windows-based and was a strange mix of the proprietary VBScript language and HTML. This meant that we often saw code that looked like this:

<%
Dim connection
Set connection = Server.CreateObject("ADODB.Connection")
Response.Write "The server connection has been created for id " & Request.QueryString("id")
%>
<H1>Hello World</H1>
