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.

Designing RESTful APIs with OpenAPI and Swagger

Designing focuses on the core principles while creating web services. Instead of coding from the start, we will describe how to design a web service first, and then make it ready for coding. In this chapter, we will describe OpenAPI principles and implementation principles, which will help you when you design your own web services. This will help your web service support future changes and requirements. Finally, we will spend some time describing what to expose on a web service and what to accept when receiving a request.

The following topics will be covered in this chapter:

  • API-first concepts
  • The OpenAPI Specification
  • Design maturity and implementation
  • Minimal API surface
  • Robustness and extendibility
  • Swagger tooling
