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.

This chapter has followed a long path inside Fastify’s internals to unveil the JSON schema’s power. Now you understand why defining a JSON Schema is a critical phase in your application setup. It can be a hard task, but data validation and a fast response are the two main reasons to do this.

We have looked at the JSON Schema specification’s basics and how to use it in our routes, adopting the default Fastify components. We did not step back to configure these components, and now you have seen the whole process, you can control them to reach your goals.

It has not been easy. The concepts in this chapter are the most misused by developers that use Fastify. You did a great job, and I hope the diagrams have helped you follow the logic behind the validation and the serialization.

This chapter is the last theoretical one: congratulations! In many chapter’s sections, we read concepts that were already discussed in the previous chapters. This is...
