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.

Creating a Markdown Editor with TypeScript

It is hard to deal with content on the internet without encountering markdown. Markdown is a simplified way to create content using plain text that is easily converted into simple HTML. In this chapter, we are going to investigate what it takes to create a parser that will convert a subset of the markup format into HTML content. We will automatically convert relevant tags into the first three header levels, the horizontal rule, and paragraphs.

By the end of this chapter, we will have covered how to create a simple Bootstrap web page and reference the JavaScript generated from our TypeScript, as well as hooking up to a simple event handler. We will also cover how to create classes using simple design patterns and how to design classes with single responsibilities, which are techniques that serve us well as professional developers.
