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.

The Plugin System and the Boot Process

A Fastify plugin is an essential tool at the disposal of a developer. Every functionality except the root instance of the server should be wrapped in a plugin. Plugins are the key to reusability, code sharing, and achieving proper encapsulation between Fastify instances.

Fastify’s root instance will load all registered plugins asynchronously following the registration order during the boot sequence. Furthermore, a plugin can depend on others, and Fastify checks these dependencies and exits the boot sequence with an error if it finds missing ones.

This chapter starts with the declaration of a simple plugin and then, step by step, adds more layers to it. We will learn why the options parameter is crucial and how the Fastify register method uses it during the boot sequence. The final goal is to understand how plugins interact with each other thanks to encapsulation.

To understand this challenging topic, we will introduce and learn...
