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.

Chapter 6

  1. Before you write the code itself following TDD practices.
  2. A model is the representation of a resource. For example, if we have a user resource, the user model could be as follows:
export interface User {
id: Number
username: String
firstName: String
lastName: String
email: String
password: String
phone: String
userStatus: Number
  1. Take the following URI:

You can get the query order-status as follows:

export let getInventory = (req: Request, res: Response, next: NextFunction) => {
const status = req.query.status
  1. You can pass unlimited query strings.
  2. It should only contain route information and point the methods to the controllers that will handle and process the operation, as follows:
import * as orderController from '../controllers/order'

export class OrderRoute {
public routes(app...
