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.

Implementing the routes

Until now, we implemented our handlers as dummy functions that don’t do anything at all. This section will teach us how to save, retrieve, modify, and delete actual to-do tasks using MongoDB as the data source. For every subsection, we will examine only one handler, knowing that it will replace the same handler we already defined in ./routes/todos/routes.js.

Unique identifiers

This section contains several code snippets and commands to issue in the terminal. It is important to remember that the unique IDs we show here are different from the ones you will have when testing the routes. In fact, the IDs are generated when a task is created. Change the command snippets accordingly.

We will start with createTodo since having items saved on the database will help us implement and test the other handlers.


As the name implies, this function allows users to create new tasks and save them to the database. The following code snippet defines...
