Error: listen EACCES: permission denied 0.0.0.0:443

Question

When running npm start showing this permission issue.

 Error: listen EACCES: permission denied 0.0.0.0:443
    at Server.setupListenHandle [as _listen2] (node:net:1302:21)
    at listenInCluster (node:net:1367:12)
    at Server.listen (node:net:1454:7)

did you have any service that currently working on port 443 ? — mohammad Naimi, Aug 31 '21 at 14:24
no, if the port engaged with any service, I think error will be port in use instead of above error message. — MUHAMMAD SHAHID RAFI C P, Aug 31 '21 at 14:37
You need root or equivalent privilege to listen on port lesser than 1024. Please run the app with sudo — null, Aug 31 '21 at 14:46

Running server with npm on https port 443 was fine with sudo. Until I had to upgrade npm (from v6 to v8). And googling initially didn't help, because everyone is suggesting sudo.

Found duplicate answer here. Referring to another site.

A lot of people get stuck here, but the solution is easy. There a few options but this is the one I like. Type the following commands:

sudo apt-get install libcap2-bin 
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``

Now, when you tell a Node application that you want it to run on port 80, it will not complain.

This is also a very typical issue when running servers inside a WSL Linux distro. Thank you — Greg, Feb 22 '23 at 19:49
