Overview of this book

This book is a complete guide to server-side app development in Fastify, written by the core contributors of this highly performant plugin-based web framework. Throughout the book, you’ll discover how it fosters code reuse, thereby improving your time to market. Starting with an introduction to Fastify’s fundamental concepts, this guide will lead you through the development of a real-world project while providing in-depth explanations of advanced topics to prepare you to build highly maintainable and scalable backend applications. The book offers comprehensive guidance on how to design, develop, and deploy RESTful applications, including detailed instructions for building reusable components that can be leveraged across multiple projects. The book presents guidelines for creating efficient, reliable, and easy-to-maintain real-world applications. It also offers practical advice on best practices, design patterns, and how to avoid common pitfalls encountered by developers while building backend applications. By following these guidelines and recommendations, you’ll be able to confidently design, implement, deploy, and maintain an application written in Fastify, and develop plugins and APIs to contribute to the Fastify and open source communities.

What is a plugin?

A Fastify plugin is a component that allows developers to extend and add functionalities to their server applications. Some of the most common use cases for developing a plugin are handling a database connection or extending default capabilities – for example, to request parsing or response serialization.

Thanks to their unique properties, plugins are the basic building blocks of our application. Some of the most prominent properties are the following:

  • A plugin can register other plugins inside it.
  • A plugin creates, by default, a new scope that inherits from the parent. This behavior also applies to its children and so on, although using the parent’s context is still possible.
  • A plugin can receive an options parameter that can be used to control its behavior, construction, and reusability.
  • A plugin can define scoped and prefixed routes, making it the perfect router.

At this point, it should be clear that where other frameworks...
