Can someone explain to me what the purpose of PM2? What are the implementations? Why is it any different from running with the node command? A basic explanation would be appreciated.

PM2 is a process manager that enables you to have an easy way of managing and demonizing your application. Basically, it will run your Node.js application in the background as a service. PM2 helps you to facilitate product-level deployments, which require running applications alive indefinitely.
# To install PM2
npm install -g pm2
# To start the application
pm2 start app.js --name "test-application"
# To check the status
pm2 status
# To restart all applications
pm2 restart all
# To check logs
pm2 logs
