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.

How to analyze the data

Following the Optimization Cycle, we must analyze the measurement result to understand the following:

  • Can the application performance be improved?
  • Where should we focus first?
  • How can we improve it?
  • Where is the bottleneck?

For example, if we analyze Figure 13.3, the handler spends most of its time on the MongoDB find operation. This means that we should focus on that part, trying to check whether the following applies:

  • We have set the connection pool correctly
  • We have created a dedicated index

Based on whether this is the case or not, you can define some boundaries that can be further optimized in the next Optimization Cycle step.

Of course, when monitoring all the application’s routes, we will need many filters to select all the routes that require our attention, such as slow endpoints or APIs with a high error rate.

Note that, at times, the data cannot be as detailed as in this example. Let’...
