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.

Exploring Hooks

In this chapter, we will learn what makes Fastify different from the majority of other web frameworks. In fact, contrary to several other frameworks that have the concept of middleware, Fastify is based on hooks. They all have different use cases, and mastering their usage is key to developing stable and production-ready server applications.

Even if the topic is considered somehow complex, the goal of the subsequent sections is to give a good overview of how the Fastify framework “thinks” and build the right confidence in using these tools.

Before going into their details, though, we need to introduce another concept that makes everything even possible. Namely, we need to learn about the lifecycle of Fastify applications.

In this chapter, we will focus on these concepts:

  • What is a lifecycle?
  • Declaring hooks
  • Understanding the application lifecycle
  • Understanding the request and reply lifecycle
