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.

  1. GraphQL is an open source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data.
  2. GraphQL enables the possibility of avoiding over-fetching data and enables rapid product development.
  3. Yes. It is open source under Facebook's license, and is available at https://opensource.fb.com.
  4. Yes. You can get the data from wherever you want and use GraphQL.
  5. GraphQL Playground is a graphical, interactive, in-browser GraphQL IDE, created by Prisma and based on GraphQL.
  6. The most basic components of a GraphQL schema are object types, which represent a kind of object you can fetch from your service, and what fields it has. The following is an example:
type Character {
name: String!
appearsIn: [Episode!]!
}
  1. It is when something might change the data state, such as creating a new object or updating an existing one, as follows:
