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.

Understanding the project overview

Now that we have a grasp of some of the concepts that we are going to cover throughout the rest of this book, we are going to start putting them into practice by creating a project that parses a very simple markdown format while the user types into a text area and displays the resulting web page alongside it. Unlike full markdown parsers, we are going to concentrate on formatting the first three header types, the horizontal rule, and paragraphs. The markup is restricted to breaking lines down by newline characters and looking at the start of a line. It then determines whether or not a particular tag is present and, if not, it assumes the current line is a paragraph. The reason we have chosen this implementation is because it is a simple task to pick up immediately. While it is simple, it offers sufficient depth to show that we are going to tackle...
