Mastering TypeScript - Fourth Edition

By: Nathan Rozentals

Overview of this book

TypeScript is both a language and a set of tools to generate JavaScript, designed by Anders Hejlsberg at Microsoft to help developers write enterprise-scale JavaScript. Mastering Typescript is a golden standard for budding and experienced developers. With a structured approach that will get you up and running with Typescript quickly, this book will introduce core concepts, then build on them to help you understand (and apply) the more advanced language features. You’ll learn by doing while acquiring the best programming practices along the way. This fourth edition also covers a variety of modern JavaScript and TypeScript frameworks, comparing their strengths and weaknesses. You'll explore Angular, React, Vue, RxJs, Express, NodeJS, and others. You'll get up to speed with unit and integration testing, data transformation, serverless technologies, and asynchronous programming. Next, you’ll learn how to integrate with existing JavaScript libraries, control your compiler options, and use decorators and generics. By the end of the book, you will have built a comprehensive set of web applications, having integrated them into a single cohesive website using micro front-end techniques. This book is about learning the language, understanding when to apply its features, and selecting the framework that fits your real-world project perfectly.

Building an API

Now that we have a working AWS SAM CLI environment configured, we can build an API. The API that we will build in this chapter will be used to support the three existing applications that we have been building throughout this book, in Angular, React, and Vue. Our Angular application, which we built in Chapter 11, Angular, revolved around a user logging in to an application. This means that we will need to store and retrieve user details from a database.

The React application that we built in Chapter 12, React, showed a list of products for sale, and when a particular product was chosen, it would show the details of the product. To support this, we will need to store and then retrieve our products from a database, and allow for the generation of a list of available products. We also included the option of selecting how many of these products to add to a shopping cart.

The Vue application that we built in Chapter 13, Vue, was responsible for displaying a user...
