pm2-exit-hook

pm2-exit-hook

Run some code when the process exits

The process.on('exit') event doesn't catch all the ways a process can exit. This module catches:

• process SIGINT, SIGTERM and SIGHUP signals
• process beforeExit and exit events
• PM2 clustering process shutdown message (PM2 graceful reload)

Useful for cleaning up. You can also include async handlers.

Forked from exit-hook Supports pm2 cluster mode.

Install

$ npm install --save pm2-exit-hook

Usage

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

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

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

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

// you can add async hooks by accepting a callback
exitHook(callback => {
	setTimeout(() => {
		console.log('exiting 3');
		callback();
	}, 1000);
});

throw new Error('unicorns');

//=> 'exiting'
//=> 'exiting 2'
//=> 'exiting 3'
