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.

Building a Chat Room Application Using Socket.IO

In this chapter, we are going to cover how to build an Angular chat room application using Socket.IO in order to delve into the ability to send messages back and forth between the client and server without having to establish REST APIs or through the use of GraphQL queries. The technology we are going to use involves the establishment of a long-running connection from the client to the server, making communication as simple as passing a message.

In this chapter, we are going to cover the following topics:

  • Long-running client/server communications using Socket.IO
  • Creating a Socket.IO server
  • Creating an Angular client and adding Socket.IO support
  • Using decorators to add client-side logging
  • Using Bootstrap in our client
  • Adding Bootstrap navigation
  • Signing up to Auth0 to authenticate our client
  • Adding Auth0 support to our client
  • Adding...
