capture-exit

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

exit-hook

exit-hook is a similar package that provides functionality to execute cleanup code when a Node.js process exits. Compared to capture-exit, exit-hook has a simpler API but does not handle uncaught exceptions by default.

async-exit-hook

async-exit-hook extends the basic functionality of exit-hook by supporting asynchronous cleanup functions. This is useful for handling tasks that require a bit more time to complete, such as asynchronous database shutdowns. It is similar to capture-exit in managing async operations but differs in API and additional configuration options.
