nginx node js

[Abhishek0943]

in this tutorial you add a line "root : var/html/index.html "
but in nodeexpress tutorial how they know which file you want to target
like i have node server in /home/app/node_files
then run pm2 start entryfile or pm2 start ecosystem.config.cjs
how sites-avaliable know who is our index file or entry file
