Chapter 10. Deploying Node.js Applications

Now that the Notes application is fairly complete, it's time to think about how to deploy it to a real server. We've created a minimal implementation of the collaborative note concept that works fairly well. To get input and advice from others, Notes needs to escape our laptop and live on a real server. Therefore, the goal of this chapter to look at a couple of deployment methods for Node.js applications.

In this chapter, we will cover the following topics:

• Traditional LSB-compliant Node.js deployment

• Using PM2 to improve reliability

• Deployment to a Virtual Private Server provider

• Microservice deployment with Docker (we have four distinct services to deploy)

• Deployment to a Docker hosting provider

The first task is to duplicate the source code from the previous chapter. It's suggested to create a new directory, chap10, as a sibling of the chap09 directory and copy everything from chap09 to chap10.
