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.

Performance Assessment and Improvement

We all know that Fastify is fast – but is your code fast enough for Fastify? Learn how to measure your application’s performance to improve your business value and the quality of your code. By analyzing the metrics, you will avoid introducing speed regressions and identify bottlenecks or memory leaks that could crash your system. You will learn how to add an instrumentation library to a Fastify application to analyze how the server reacts to a high volume of traffic. We will get an overview to understand and act accordingly depending on your measurements to maintain your server’s performance and its healthy status.

This is the learning path we will take in this chapter:

  • Why measure performance?
  • How to measure an application’s performance
  • How to analyze the data
  • How to optimize the application
