# crossplatform-killport

[![npm](https://img.shields.io/npm/v/crossplatform-killport.svg)](https://www.npmjs.com/package/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](https://github.com/orgs/rooseveltframework/people) 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](https://nodejs.org) 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
```

Windows users may need to run `Set-ExecutionPolicy Unrestricted` on their terminal to permit the script to run. See [docs](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_execution_policies) from Microsoft for more information.

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_modules/.bin/killport 8080
```

Use from within Node.js code:

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