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.

API-first concepts

In general, API-first design is a software development approach in which API design is prioritized. With that in mind, it is possible to generate gains in scalability, flexibility, agility, and performance for your system. When opting for API-first design, developers can facilitate discussions with stakeholders such as their internal team, clients, or any other teams within the organization who wish to consume the API. This mutual collaboration allows the team who is building the API to create user stories, mock-ups, and documentation.

There are a few tools that use an API description language to help teams adopt an API-first technique. This description language helps create a balance around the contract, which will be used by the API. Basically, writing a well-defined contract means that some considerable time will be spent on the API's design.
