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.

Manual testing

Since we have everything in place with MongoDB, it is time to start the application and run some tests manually. We will do so using the following steps:

  1. To start the application, run the following command:
$ npm run dev

  1. Go to the POSTman application and create a new user:
POST operation to create a new user
  1. Now, try to retrieve it using the GET operation:
Retrieving the user through the GET method
  1. Try to create more users and then create orders for them all:
Creating orders using the POST operation for the new users created
  1. Finally, call the URI. inventory :
Orders inventory
  1. To make sure the documents are stored on MongoDB, check them using the Robomongo client. Users will be shown the following:

Users created and stored on MongoDB

The orders will be shown as follows:

Orders created with the new users and stored on MongoDB
