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.

This chapter has explained how routing works in Fastify, from route definition to request evaluation.

Now, you know how to add new endpoints and implement an effective handler function, both async or sync, with all the different aspects that might impact the request flow. You know how to access the client’s input to accomplish your business logic and reply effectively with a success or an error.

We saw how the server context could impact the route handler implementation, executing the hooks in that encapsulated context and accessing the decorators registered. Moreover, you learned how to tweak the route initialization by using the onRoute hook and the route’s config: using Fastify’s features together gives us new ways to build software even more quickly!

The routing has no more secrets for you, and you can define a complete set of flexible routes to evolve thanks to the constraints and manage a broad set of real-world use cases to get things done...
