PM2 VS Nodemon.io

GitHub: PM2 Repository

You can run the command pm2 status to check if both servers are online and running, as shown below. To learn about all of the other PM2 commands, read the documentation on PM2 Process Management Quick Start:

For teams using NGINX+PM2, moving to NGINX + HashiStack is a more robust and flexible solution—a great fit for startups looking for scalability without the complexity of Kubernetes.

What we wanted was something like a supercharged pm2, but multi-node with good support for both docker and binaries.

Start by registering the app using the official guide.

Run the application using PM2 (ref: Process manager for Node.js)

We will need some help with the development process, that is why we will use nodemon. Nodemon is a utility tool that automatically monitors changes in your Node.js application's source code and restarts the server whenever it detects any modifications. This tool helps streamline the development process by eliminating the need to manually stop and restart the Node.js server every time you make changes to the code, making it easier to see the effects of your changes immediately. We will use "npm install --save-dev nodemon" to install nodemon to the development section of our project. Also, we need to add a new setting to the scripts part of the package.json file that will start nodemon.

I’m sure you’ve used different tools to watch your source files and restart the application when you change your code. We’ve done this in various ways, one of which is using nodemon, a utility that monitors changes in your source files and automatically restarts the server.

I installed Nodemon to help here. For those who don't know already, Nodemon is a tool that helps by restarting the Node application everytime a change has been made to the code. This proved to be quite helpful as the trial & error was about to begin.

Nodemon is a dependency that monitors your project files for changes and automatically restarts the server once there is a change to any file being watched by nodemon. Think of nodemon as node monitor ;). Note: You shouldn't use nodemon on a production server, except you're part of the developers that attempt fix bug in production, lol.

nodemon - automatically restarts our Node.js server whenever we make changes to the codebase

The nodemon is a popular library for running and restarting Node.js processes on file changes. All LTS Node.js support an option --watch-path, which allows to replace nodemon:

Or you can install nodemon for the same purpose. nodemon detects changes in the directory and restarts your application.

When I first encountered Node.js and also learned how to use Linux, nodemon was a library that I often used to develop applications, as it would automatically "reload" the new code upon saving without needing to manually "kill" and restart the application, a feature now commonly referred to as "hot reload."
