Terminate Process on a Port from Command Line
Once a week I have to deal with a zombie process or try to start a process that's already running on its designated port. In most cases I use macOS's Activity Monitor to kill the process, which is time-consuming. What if we could just kill a process on a given port from command line? Well, we can!
To terminate a process on a given port, install kill-port
and starting nuking those zombies via:
# yarn global add kill-port
# Kill processes on multiple ports
kill-port 6060 8000
If you want to programmatically kill a port that you want to ensure your app will run on, you can do that as well:
const kill = require('kill-port')
kill(6060, 'tcp')
.then(console.log)
.catch(console.log)
I look forward to incorporating this library into my Node.js sites so that I can clear the way for a given port and avoid zombie processes.

I'd bet one of the most used MooTools methods is the setStyle()
method, which allows you to set CSS style declarations for an element. One of the limitations of MooTools' setStyle()
method is that it sets the specific style for all medias.
