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.

Exposing our microservice via an API gateway

We have split our monolith into two microservices. However, we would still need to expose them under a single origin (in web terminology, the origin of a page is the combination of the hostname/IP and the port). How can we do that? We will cover an Nginx-based strategy as well as a Fastify-based one.

docker-compose to emulate a production environment

To demonstrate our deployment scenario, we will be using a docker-compose setup. Following the same setup as in Chapter 10, let’s create a Dockerfile for each service (v1 and v2). The only relevant change is replacing the CMD statement at the end of the file, like so:

CMD ["node", "server.js"]

We’ll also need to create the relevant package.json file for each microservice.

Once everything is set up, we should be able to build and run both v1 and v2 that we just created. To run them, we set up a docker-compose-two-services.yml file like the following...
