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.

Loading route schemas

Before implementing the schemas, let’s add a dedicated folder to organize our code base better. We can do it inside the ./routes/todos/ path. Moreover, we want to load them automatically from the schemas folder. To be able to do that, we need the following:

  • A dedicated plugin inside the schemas folder
  • A definition of the schemas we wish to use
  • An autohooks plugin that will load everything automatically when the todos module is registered on the Fastify instance

We will discuss these in detail in the following subsections.

Schemas loader

Starting with the first item of the list we just discussed, we want to create a ./routes/todos/schemas/loader.js file. We can check the content of the file in the following code snippet:

'use strict'
const fp = require('fastify-plugin')
module.exports = fp(async function schemaLoaderPlugin (fastify, opts) { // [1]
