Run node.js on port less than 1024 without sudo
Normally, to run a program that bind to port less than 1024, it needs to be run as sudo. But not anymore, we can use this solution: https://gist.github.com/firstdoit/6389682
sudo setcap 'cap_net_bind_service=+ep' `which node`
After this, we can run node normally without sudo but still can bind to port 443 etc.
Why not just run as sudo?
Because nvm is per-user, per-shell. And running node as root is not a good practice.
