How to kill the process currently using a given port on Windows

Sometimes when I tried running my Angular application and saw this message.

An unhandled exception occurred: Port 4200 is already in use. Use ‘—port’ to specify a different port.

To simple kill the process that is running on a specific port, run this command:

npx kill-port 4200

Where 4200 is the port that needs to be stopped.

And the result is satisfying.

You must have [email protected]^ version to run npx, which means as the minimum of npm running on your machine must be 5.2.0 or greater.
