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.

Writing good tests

Implementing tests for an application is an investment to free you up from the stress that a new project could give you. Thanks to these tests, you can be (pretty) sure of implementing new features or fixing bugs without breaking the existing software. Unfortunately, writing tests often gets sacrificed whenever a project is running out of time. This is also an activity that many consider to be boring and frustrating, due to the many blockers you may face by testing an HTTP server, such as the server port already in use. So, the tests are often written quickly and without the required attention.

We can say that an application’s test suite is successful under the following conditions:

  • It’s automated – you just need to click a button to get many hours’ worth of work done
  • It’s easy to maintain – adding a new test must be easy, and it should not take more time than developing the feature itself
  • Running the tests...
