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.

Flexible APIs with GraphQL

GraphQL is a new approach to serving data. Some people even define GraphQL as REST 2.0. In this chapter, we will take a look at the differences and similarities between GraphQL and REST. You will also learn how to add support for GraphQL to your existing RESTful API. With some examples of querying data, as well as validating and executing a query, you will learn how to benefit the most from using GraphQL with your RESTful APIs.

The following topics will be covered in this chapter:

  • Introduction to GraphQL
  • Adding support for GraphQL to your REST API
  • Queries
  • Schemas and types
  • Execution
