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.

Angular Cloud-Based Mapping with Firebase

We have spent quite a few chapters writing our own backend systems for returning information to the client. In the last few years, there has been a trend toward using third-party cloud systems. Cloud systems can help lower the costs of writing applications, because other companies provide all of the infrastructure that we need to use and take care of testing, upgrades, and so on. In this chapter, we are going to look at using cloud infrastructure from the Bing mapping team and Firebase to provide data storage.

The following topics will be covered in this chapter:

  • Signing up to Bing mapping
  • The implications of billable cloud features
  • Signing up to Firebase
  • Adding a map component
  • Using map search features
  • Using EventEmitter to notify parent components of child component events
  • Reacting to mapping events to add and remove your own points...
