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.

HTTP methods for RESTful services

The use of HTTP verbs allows a clear understanding of what an operation is going to do. In general, the primary or most commonly used HTTP verbs are POST, GET, PUT, PATCH, and DELETE, which stand for create, read, update (PATCH and PUT), and delete, respectively. Of course, there are also a lot of other verbs, but they are not used as frequently:

Method HTTP method description
GET GET is the most common HTTP verb. Its function is to retrieve data from a server at the specified resource.

For example, a request made to the GET https://<HOST>/customers endpoint will retrieve all customers in a list format (if there is no pagination).

There is also the possibility of retrieving a specific customer such as GET https://<HOST>/customers/1234; in this instance, only the customer with the 1234 ID will be retrieved.
