Usually I exploit macOS’s Exercise Monitor to kill the method, which is time-consuming. What if we might simply kill a course of on a given port from command line? Properly, we are able to!

To terminate a course of on a given port, set up kill-port and beginning nuking these zombies by way of:

# yarn international add kill-port

# Kill processes on a number of ports
kill-port 6060 8000

If you wish to programmatically kill a port that you simply wish to guarantee your app will run on, you are able to do that as properly:

const kill = require('kill-port')

kill(6060, 'tcp')
      .then(console.log)
      .catch(console.log)

I look ahead to incorporating this library into my Node.js websites in order that I can clear the best way for a given port and keep away from zombie processes.
