Node Restart in Shell Script

I want to rerun the node server, whenever there's changes in file, but i want to use fswatch. i am using fswatch with the shell script like

nohup node server.js &

but i can't run the same script again since it will throw EADDRINUSE.

• whats the best way to restart the node via script with the help of fswatch (or alternate, without any new installation) ?


• Why node doesn't have something like node restart?

what i could think of is get pid from ps and kill it with script, but i guess there should be a better solution.
