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.

Testing with Postman

Postman is an application that allows developers to perform HTTP requests from a simple and intuitive interface, making it easy to test and debug REST services.

Postman is available as an application for the Google Chrome browser and has several useful features for developing this type of project. We can use it to test the actions of an ASP.NET Web API service by sending and receiving data in JSON format.

The documentation for Postman is available at

The installation is really simple—you just have to download a version based on your operating system and follow the installation instructions that appear onscreen. The installation file is available at

Once the installation has completed, you can launch Postman and use it to test endpoints, like so:

Consuming a REST endpoint with...
