Node.js Web Development - Fifth Edition

By: David Herron

Overview of this book

Node.js is the leading choice of server-side web development platform, enabling developers to use the same tools and paradigms for both server-side and client-side software. This updated fifth edition of Node.js Web Development focuses on the new features of Node.js 14, Express 4.x, and ECMAScript, taking you through modern concepts, techniques, and best practices for using Node.js. The book starts by helping you get to grips with the concepts of building server-side web apps with Node.js. You’ll learn how to develop a complete Node.js web app, with a backend database tier to help you explore several databases. You'll deploy the app to real web servers, including a cloud hosting platform built on AWS EC2 using Terraform and Docker Swarm, while integrating other tools such as Redis and NGINX. As you advance, you'll learn about unit and functional testing, along with deploying test infrastructure using Docker. Finally, you'll discover how to harden Node.js app security, use Let's Encrypt to provision the HTTPS service, and implement several forms of app security with the help of expert practices. With each chapter, the book will help you put your knowledge into practice throughout the entire life cycle of developing a web app. By the end of this Node.js book, you’ll have gained practical Node.js web development knowledge and be able to build and deploy your own apps on a public web hosting solution.

Creating a Docker stack file for deployment to Docker Swarm

In the previous sections, we learned how to set up an AWS infrastructure using Terraform. We've designed a VPC that will house the Notes application stack, we experimented with a single-node Docker Swarm cluster built on a single EC2 instance, and we set up a procedure to push the Docker images to the ECR.

Our next task is to prepare a Docker stack file for deployment to the swarm. A stack file is nearly identical to the Docker compose file we used in Chapter 11, Deploying Node.js Microservices with Docker. Compose files are used with normal Docker hosts, but stack files are used with swarms. To make it a stack file, we add some new tags and change a few things, including the networking implementation.

Earlier, we kicked the tires of Docker Swarm with the docker service create command to launch a service on a swarm. While that was easy, it does not constitute code that can be committed to a source repository, nor is it an...
