Overview of this book

In the world of web development, leveraging data is the key to developing comprehensive applications, and RESTful APIs help you to achieve this systematically. This book will guide you in designing and developing web services with the power of TypeScript 3 and Node.js. You'll design REST APIs using best practices for request handling, validation, authentication, and authorization. You'll also understand how to enhance the capabilities of your APIs with ODMs, databases, models and views, as well as asynchronous callbacks. This book will guide you in securing your environment by testing your services and initiating test automation with different testing approaches. Furthermore, you'll get to grips with developing secure, testable, and more efficient code, and be able to scale and deploy TypeScript 3 and Node.js-powered RESTful APIs on cloud platforms such as the Google Cloud Platform. Finally, the book will help you explore microservices and give you an overview of what GraphQL can allow you to do. By the end of this book, you will be able to use RESTful web services to create your APIs for mobile and web apps and other platforms.

Building Your First API

Your first API, Hello World, will mainly focus on how to start the app that is going to serve as your web service. This chapter will describe file organization and folder structures so that we can create a more maintainable and scalable code base. Then, we will focus on how to define routes with a very classic Hello World output as a result of a web service call. Finally, we will show you the controller logic that is going to run when a certain endpoint is called.

Throughout this book, we are going to create a simple Order Management System (OMS), which will connect with a NoSQL database. The main output of this service is to expose a REST API. This chapter will start this engagement from a basic Hello World service, which will reshape itself accordingly.

The following topics will be covered in this chapter:

  • Serving the app
  • File structure
  • Defining basic...
