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.

Sharing the application configuration across plugins

The Loading the plugins’ configurations section discussed how a plugin could access the application configuration. In this case, the plugin accesses the fastify.secret plain object to access the environment variables.

The configuration may evolve and become more complex. But, if you just intended to centralize the whole plugin’s settings into a dedicated plugin, how could you do that?

We can modify the config.js plugin and move it to the configs/ directory. By doing this, we are not loading it automatically anymore. Then, we can integrate the @fastify/mongodb configuration:

module.exports = fp(async function configLoader (fastify, opts) {
  await fastify.register(fastifyEnv, {
    confKey: 'secrets',
    schema: fastify.getSchema('schema:dotenv')
  fastify.decorate('config', {
