nodeJS file — main.js
Have a website with button which can call function from main.js. I not know how restart nodeJS script correctly. Now I run process.exit() in main.js and then, with nodemon trying restart application but nodemon tell me “[nodemon] clean exit - waiting for changes before restart”. So how correctly restart application?
Clean exit means exit code 0, which means, "Everything is okay! I intended to exit." Usually, programs that exit normally don't specifically intend to be restarted. nodemon is choosing to consider that the end of the program's operation, which isn't a totally insane thing. However, nodemon being a process manager for daemons, probably ought to just restart it anyway. I would suggest using PM2 instead, it is what most people use in production and it will correctly restart the process since its whole job is to keep services running.
Aside from all of that, I want to note that allowing a browser to restart your app is probably not a good idea. If you have carefully designed your app to be stateless and handle random shutdowns and it is clustered, etc. then maybe it is fine. But generally I would not recommend it. At the very least, make sure the request is authenticated and authorized.
