capture-exit


Allow cooprative async exit handlers, we unfortunately must hijack
process.exit.

It allows a handler to ensure exit, without that exit handler impeding other
similar handlers

for example, see: sindresorhus/ora#27

Differences between process.on('exit') and captureExit.onExit(...) => https://github.com/ember-cli/capture-exit/issues/12

``sh
yarn add capture-exit
// or
npm install --save capture-exit
`

$3

`js
// as early in startup as possible
require('capture-exit').captureExit();

// when you want to schedule some work on exit:
function onExit() {
return something.processWillExit(); // you can return promises, which will pause exit until fulfilled
}

require('capture-exit').onExit(onExit); // add an exit handler
require('capture-exit').offExit(onExit); // allows one to remove an exit handle if it is not longer required
