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.

Using Fastify type-providers

A Fastify type-provider is a TypeScript-only package that simplifies the definition of JSON schemas by providing type annotations and generics. Using it will allow Fastify to infer type information directly from schema definitions. Type-providers enable developers to define API endpoints’ expected input and output data easily, automatically check the type correctness at compile time, and validate the data at runtime.

Fastify supports several type-providers, such as json-schema-to-ts and TypeBox. In TypeScript projects, using a type-provider can help reduce the boilerplate code required for input validation and reduce the likelihood of bugs due to invalid data types. This can ultimately make your code more robust, maintainable, and scalable.

For the sake of brevity, in the following example, we will focus only on the TypeBox type-provider. However, since which type-provider you use is based on personal preference, we encourage you to try other...
