how to kill a node server code example

Example 1: kill node process

The Difference Between kill and pkill
The kill command is a wrapper to the kill system call, which knows only about process IDs. pkill can determine the process ID based on things like, process name, owner of the process or session id.

Syntax:
$ kill 1234
$ pkill -f node

Example 2: stop npm server

npm run react-scripts start

Example 3: ran ctrl c and npm server is still running

killall node
