Kill-port-process

Cross-platform module to stop one (or more) process(es) running on a port (or a list of ports).

Install

$ npm install kill-port-process
# or
$ yarn add kill-port-process

Usage

Programmatically

const { killPortProcess } = require('kill-port-process');

(async () => {
  // long running process running on a given port(s), e.g. a http-server
  // takes a number, number[], string or string[]
  // single port
  await killPortProcess(1234);

  // multiple ports
  await killPortProcess([1234, 6789]);

  // with options
  await killPortProcess(1234, { signal: 'SIGTERM' });
})();

Options

• signal (optional): used to determine the command used to kill the provided port(s). Valid values are:
  • SIGKILL (default)
  • SIGTERM

CLI

Install the module globally:

npm install kill-port-process -g

You can use the CLI calling it with kill-port <port>.

It takes a single port or a list of ports separated by a space. Valid flags are -p and --port but are both optional.

$ kill-port 1234
# or multiple ports, separated by space(s)
$ kill-port 1234 2345
# or
$ kill-port -p 1234
# or
$ kill-port --port 1234

Flags

• --graceful kill the process gracefully.
  • Unix: Sends a -15 signal to kill (SIGTERM) rather than -9 (SIGKILL)
  • Win: Currently no use

Compatibility

Compiled for es5 and supported by node v16 and onwards.
