How can I run my nodejs with nodemon on port 80

Question

I have my nodejs running on port 9090 and I somehow made it work on port 80 by using the following setup

sudo apt-get install libcap2-bin sudo setcap cap_net_bind_service=+ep

and when I run as nodejs server.js 80, I'm able to run my client as localhost without any port specified.

But when I run the same with nodemon server.js 80, it throws an error

Error: listen EACCES 0.0.0.0:80

How can I run it with nodemon and port 80

Thanks in advance.

You most likely need elevated privileges to bind to a port below 1024. try sudo nodemon server.js 80.

Is this the same unix machine with nodemon installed? – Sello Mkantjwa Oct 31 '17 at 09:29
What happens when you run sudo nodejs server.js? – Sello Mkantjwa Oct 31 '17 at 11:52
It works fine, but will not restart on any uncaught error. – kumar Oct 31 '17 at 11:55
Thats odd. Command not found? Are you sure nodemon is installed and you didnt make a typo? – Sello Mkantjwa Oct 31 '17 at 12:01

You need root permissions to run on 'privileged' ports, so run it as sudo. I advise you to use a proxy like nginx for proxying your requests to ports such as 80, or atleast re-routing your traffic via iptables (how-to here).
