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.

Enhancing the default logger configuration

You know the options available in the logger, but what is a valuable configuration, and how can we integrate it into our application? First of all, we need to define which logs we expect for every request:

Figure 11.1 – Request logs logic

Figure 11.1 – Request logs logic

As shown in Figure 11.1, we expect these log lines for each request: one for the incoming request, optionally, how many handler’s log messages you implement, and finally, one for the response output. All these log lines will be connected to each other by the reqId (request-id) field. It is a unique identifier generated for each request whenever the server receives it. We already described the reqId property in Chapter 1 in the The Request component section.

We can start implementing this by doing the following:

  • Exploiting the default request and response log implemented by Fastify
  • Executing a custom log statement by using the onRequest and onSend...
