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.

Adding the authorization layer

Now that we can have all authentication pieces in place, we can finally move on to implementing the authorization layer of our application. To adequately protect our endpoints, we need to do two main things to the ./routes/todos module from Chapter 7:

  • Add the authentication layer to ./routes/todos/routes.js
  • Update the to-do data source inside ./routes/todos/autohook.js

Fortunately, we need only a one-liner change to implement the first point. On the other hand, the second point is more complex. We will examine both in the following subsections.

Adding the authentication layer

Let’s start with the simpler task. As we already said, this is a fast addition to the Chapter 7 code that we can see in the following snippet:

module.exports = async function todoRoutes (fastify, _opts) {
  fastify.addHook('onRequest', fastify.authenticate) // [1]
  // omitted route implementations from chapter 7
