FINIS

Finis

Run your callback before node exit, pass exit code and signal name as arguments

INSTALLATION

npm install finis --save

USAGE

finis() installs a callback function which will be run just before the node process exits.

The callback function will be called when:

the process exits normally
the user presses Ctrl+C
an exception is uncaught

EXAMPLE

JavaScript

const finis = require('finis')

finis((code, signal, error) => {
  console.log(`finis(${code}, ${signal}, ${error})`)
})

TypeScript

import finis from 'finis'

finis((code: number, signal: 'exit'|'SIGINT'|'SIGTERM'|'uncaughtException', error?: Error) => {
  console.log(`finis(${code}, ${signal}, ${error})`)
})

You may call finis() multiple times to install multiple callback functions.

v0.1 Dev 2016

This module is inspired by @jtlapp/node-cleanup, which is borrowed and modified from CanyonCasa's answer to a stackoverflow question. I found the code necessary for all my node projects. See the stackoverflow answer for more examples of use.
