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.

Designing the application structure

In this chapter, we will design a backend application that will expose some RESTful APIs.

The application structure enables you to write applications that are easy to implement, evolve, and maintain. A good system must be flexible to your needs and the application’s changes. Additionally, it should impose some implementation design to let you and your team avoid some major pitfalls, which could lead to an unstable and untestable application.

This chapter will discuss the application’s features only marginally. In fact, a scaffolding project should not care about them, but it should apply them to any project. For this reason, we will create an application with some health check routes and a MongoDB connection ready to be used.

We will introduce a set of Fastify plugins that will help us structure our application and reduce the burden of writing some utilities from scratch, which have already been developed and tested on production...
