The npm web server is a very simple web server used in development and testing for delivering static files.
While attempting to use start the npm web server you may see an error like this:
at exports._errnoException (util.js:746:11) at Server._listen2 (net.js:1156:14) at listen (net.js:1182:10) at net.js:1280:9 at dns.js:85:18 at process._tickCallback (node.js:355:11) at Function.Module.runMain (module.js:503:11) at startup (node.js:129:16) at node.js:814:3
One fast way to resolve the issue is:
Or, you may try the following solution to the listen EADDRINUSE error:
ps | grep node
Take note of the Process ID. Then, to free up that port, stop the process using the following.
kill <process id>
I hope this helps. Please leave a comment below.
