Fabulously kill processes. Cross-platform.

Works on macOS (10.13 or later), Linux, Windows.

npm install fkill

import fkill from 'fkill';
await fkill(1337);
console.log('Killed process');
fkill('Safari');
fkill(':8080');
fkill([1337, 'Safari', ':8080']);

Returns a promise that resolves when the processes are killed.

Type: number | string | Array<number | string>

One or more process IDs/names/ports to kill.

To kill a port, prefix it with a colon. For example: :8080.

On Windows, process extensions are optional. For example, both fkill('notepad') and fkill('notepad.exe') work.
