  res.end('Hi!')
})

server.listen(port, () => {
  setTimeout(() => {
    
    // Currently you can kill ports running on TCP or UDP protocols
    kill(port, 'tcp')

API

The module exports a single function that takes a port number as argument. It returns a promise.

CLI

You can use kill-port as a global package.

Install the package globally:

$ npm install --global kill-port
# OR
$ yarn global add kill-port

Then:

$ kill-port --port 8080
# OR
$ kill-port 9000
# OR you can use UDP
$ kill-port 9000 --method udp

You can also kill multiple ports:

$ kill-port --port 8080,5000,3000
# OR
$ kill-port 9000 3000 5000

You can also use npx to kill-port without installing:

# Kill a single port
$ npx kill-port --port 8080
$ npx kill-port 8080
# Use UDP
$ npx kill-port 9000 --method udp
# Kill multiple ports
$ npx kill-port --port 8080,5000,3000
$ npx kill-port 9000 3000 5000
