exit-hook

Run some code when the process exits

This package is useful for cleaning up before exiting.

Usage

const exitHook = require('exit-hook');

exitHook(() => {
	console.log('Exiting');
});

// You can add multiple hooks, even across files
exitHook(() => {
	console.log('Exiting 2');
});

throw new Error('🦄');

//=> 'Exiting'
//=> 'Exiting 2'

Removing an exit hook:

const exitHook = require('exit-hook');

const unsubscribe = exitHook(() => {});
