I tried myself on pm2 by starting a node app in multiple instances so its more performant by doing load balancing... main purpose was to learn how to do inter process communication in pm2 which i needed for a bigger Project
Note: Load Balancing did not work as expected on Windows, but did on Linux
Github Repo: https://github.com/Unitech/pm2
go to root directory of this project and start it with pm2 either by writing pm2 start .src/index.js into the terminal
or if you have a pm2.json which serves as a config you can also use it to start like pm2 start pm2.json
just like you would normally start the app with pm2 but adding -i which tells pm2 to run in a cluster
and a number afterwards -1 to run with all cores -1 or all if you want all or any number then it uses that number
Example: pm2 start .src/index.js -i -1
