crossplatform-killport

Command line program to kill the process running on a given port in any operating system.

Unlike many of the other programs out there that do this, this one works in Windows, Linux, and Mac, it is very easily installed in any OS using npm because it is written in Node.js, and it is actively maintained by a team of people rather than being just some guy's project from several years ago that may or may not work.

Usage

First make sure Node.js is installed on your system.

Then, to install crossplatform-killport to your system:

npm i -g crossplatform-killport

Kill whatever process is using port 8080:

killport 8080

Use via npx (this will allow you to use it without installing it to your system by downloading it from npm temporarily):

npx crossplatform-killport 8080

Use from within a Node.js project's root directory:

node node_modules/.bin/crossplatform-killport/killport.js 8080

Use from within Node.js code:

const { spawnSync, } = require('child_process')
spawnSync('node', ['node_modules/.bin/crossplatform-killport/killport.js', '8080', '--silent'], { env: process.env, shell: false, stdio: ['ignore', 'pipe', 'pipe'] })
