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.

Don’t repeat yourself

Defining the application logic inside routes is fine for simple applications such as the one in our example. In a real-world scenario, though, when we need to use our logic across an application in multiple routes, it would be nice to define that logic only once and reuse it in different places. So, once more, Fastify has us covered.

We can expand our autohooks.cjs plugin by adding what is commonly known as a data source. In the following snippet, we expand the previous plugin, adding the needed code, although, for the brevity of the exposition, we are showing only the function for the createTodo handler; you can find the whole implementation inside the book’s code repository:

'use strict'
const fp = require('fastify-plugin')
const schemas = require('./schemas/loader')
module.exports = fp(async function todoAutoHooks (fastify, opts) { // [1]
  const todos = fastify.mongo.db.collection('todos&apos...
