This is a basic NodeJS web server application, Hello world example from https://expressjs.com/en/starter/hello-world.html. See the source code in app.js for details.

The application is managed under PM2 (Process Manager 2). You can run or stop running this application using the following commands from the nodeapp folder:

pm2 start app.config.js

and

pm2 delete app.config.js

PM2 features an auto-restart mechanism that you can activate by simply changing a file in the .restart subfolder. For example, you can restart the app.js application with:

touch .restart/restart

You can change the version of the NodeJS runtime engine by supplying a complete or partial version number in the file .nvmrc (i.e. "v18" or "current" for the latest NodeJS version). Supported NodeJS versions are:

v16
v18
v20
v22

You can create your own project by simply renaming the app.js and app.config.js file; change 'app' to your own project. Don't forget to update the package.json's main property from 'app' to your own project's name.
