By: Manuel Spigolon, Maksim Sinik, Matteo Collina

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.

In this chapter, we learned about the importance of plugins and how the Fastify boot process works. Everything in Fastify can and really should be put in a plugin. It is the base building block of scalable and maintainable applications, thanks to encapsulation and a predictable loading order. Furthermore, we can use fastify-plugin to control the default encapsulation and manage dependencies between plugins.

We learned how our applications are nothing more than a bunch of Fastify plugins that work together. Some are used to encapsulate routers, using prefixes to namespace them. Others are used to add core functionalities, such as connections to databases or some other external systems. In addition to that, we can install and use core and community plugins directly from npm.

Moreover, we covered the boot process’s asynchronous nature and how every step can be awaited if needed. It is guaranteed that if any error is encountered during the loading of plugins, the boot...
