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.

Declaring API endpoints and managing the errors

An endpoint is an interface that your server exposes to the outside, and every client with the coordinates of the route can call it to execute the application’s business logic.

Fastify lets you use the software architecture you like most. In fact, this framework doesn’t limit you from adopting Representation State Transfer (REST), GraphQL, or simple Application Programming Interfaces (APIs). The first two architectures standardize the following:

  • The application endpoints: The standard shows you how to expose your business logic by defining a set of routes
  • The server communication: This provides insights into how you should define the input/output

In this chapter, we will create simple API endpoints with JSON input/output interfaces. This means that we have the freedom to define an internal standard for our application; this choice will let us focus on using the Fastify framework instead of following...
