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. The MEAN stack consists of four major components:
    • MongoDB: MongoDB is a NoSQL database that became the de facto standard in building database support into client/server applications with Node. There are other database options available, but MongoDB is a very popular choice.
    • Express: Express wraps up a log of the complications of working with server-side code under Node and makes it easier to use. For instance, if we want to deal with HTTP requests, Express makes this trivial, as opposed to writing the equivalent Node code.
    • Angular: Angular is the client-side framework that makes creating powerful web frontends easier.
    • Node: Node (or Node.js) is the runtime environment for our application on the server.
  2. We supply a prefix to make our component unique. Suppose we had a component that we wanted to call label; obviously, this will clash with the built-in HTML label....
