Port Terminator

!License
!Version

Port Terminator is an npm library for managing and terminating processes associated with specific ports on your system.

``shell
npm install port-terminator


OR


yarn add port-terminator
`

Usage

$3

Import the library in your Node.js application:

`javascript
const { portTerminator, isPortOpen, portsTerminator } = require("port-terminator");
// or using ES6 import
import { portTerminator, isPortOpen, portsTerminator } from "port-terminator";
`

$3

Use portTerminator to terminate processes associated with a single port:

`javascript
const portToTerminate = 8080;
try {
await portTerminator(portToTerminate);
console.log(Processes associated with port ${portToTerminate} terminated successfully.);
} catch (error) {
console.error(Error terminating processes for port ${portToTerminate}:, error);
}
`

$3

Use isPortOpen to check if a port is open:

`javascript
const portToCheck = 3000;
try {
const isOpen = await isPortOpen(portToCheck);
if (isOpen) {
console.log(Port ${portToCheck} is open.);
} else {
console.log(Port ${portToCheck} is closed or invalid.);
}
} catch (error) {
console.error(Error checking port status for port ${portToCheck}:, error);
}
`

$3

Use portsTerminator to terminate processes associated with multiple ports:

`javascript
const portsToTerminate = [8080, 3000, 5000];
try {
const terminationResults = await portsTerminator(...portsToTerminate);
terminationResults.forEach((response, port) => {
if (response.status) {
console.log(Processes associated with port ${port} terminated successfully.);
} else {
console.error(Error terminating processes for port ${port}:, response.error);
}
});
} catch (error) {
console.error("Error terminating processes:", error);
}
`

Command-Line Interface (CLI)

You can use port-terminator as a global package.

$3

Install the package globally using npm:

`shell
npm install --global port-terminator


OR


yarn global add port-terminator
`

#### Terminating Processes for a Single Port

To terminate processes associated with a single port, run the following command:

`shell
port-terminator 8080
`

Replace 8080 with the port number you want to terminate processes for.

#### Terminating Processes for Multiple Ports

You can also terminate processes for multiple ports by specifying multiple port numbers:

`shell
port-terminator 9000 3000 5000
`

Replace 9000, 3000, and 5000` with the port numbers you want to terminate processes for.

> Please note that you need administrative or superuser privileges to terminate processes on some systems. Ensure you have the necessary permissions before using this command.
