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 lifecycle?

When talking about a lifecycle in the context of a framework, we refer to the order in which the functions are executed. The tricky part is that application developers write only a subset of its code while the rest is developed and bundled by the framework developers.

During the application execution, the function calls bounce between internal and user-written code, and it might be hard to follow what is going on. So, it comes naturally at this point that having deep knowledge of this subject is crucial.

The lifecycle depends on the architecture of the framework. Two well-known architectures are usually used to develop a web framework:

  • Middleware-based architecture: Thanks to its more manageable learning curve, this is the most known lifecycle architecture, but time has proved it to have some significant drawbacks. When working with this architecture, an application developer must care about the order of declaration of the middleware functions since...
