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
Installation
yarn add capture-exit
// or
npm install --save capture-exit
Usage
// 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
