Kill node processes bound to a specific port (MacOS)

killnode

#!/bin/bash

touch temp.text
lsof -n -i4TCP:$1 | awk '{print $2}' >temp.text
pidToStop=$( (sed '2q;d' temp.text))
>temp.text
if [[ -n $pidToStop ]]; then
  kill -9 $pidToStop
  echo "Killed process $pidToStop running on port $1."
else
  echo "Sorry nothing running on port $1"
fi
rm temp.text

• Save file to usr/local/bin/
• Useage: killnode 3000

Will probably have to sudo to create the file, and sudo chmod a+x killnode to make it executable.
