Overview of this book

Node.js revolutionizes server-side JavaScript development and empowers developers to build efficient, scalable, and versatile applications across a range of use cases. This book is written by a Node.js core collaborator and releaser and is the only book for beginners on Node.js. It takes you on a progressive learning path that will give you the skills needed to leverage Node.js. You’ll learn Node.js fundamentals and refresh your knowledge of JavaScript before transitioning to the development of modern web applications using Node.js, Express.js, and MongoDB. You’ll get hands-on with complex topics such as asynchronous programming, npm libraries, event-driven patterns for HTTP servers, RESTful API, and JSON Web Tokens. The final chapters will walk you through the deployment process, offering insights into various strategies, including bare metal setups, virtual machines, and containerization with Docker. You’ll also be guided through the use of Process Manager 2 (PM2) for efficient process management. By the end of this Node.js book, you'll have the skills to craft, test, and deploy Node.js web applications confidently and use this powerful stack in your day-to-day projects.

Summary

In this chapter, we learned how to deploy our application to the public internet using Docker and how to use GitHub Actions for CI with our Docker images.

We learned how to use Docker to build the application and how to publish the image to Docker Hub, and we discussed how to do a proper domain setup and how to add an SSL certificate to the application using Cloudflare. We looked at the Twelve-Factor App principles and we reviewed the steps to clean up the resources that we used in this chapter.

Congratulations, you made it! This is the end of the journey. I hope that you enjoyed it and that you learned a lot. I hope that you will continue learning and improving your skills and that you will continue building amazing applications with Node.js. I will be very happy to hear from you and to know what you think about the book. You can reach me on X/Twitter (https://twitter.com/kom_256) or LinkedIn (https://www.linkedin.com/in/ulisesgascon/).
