Package Exports

capture-exit

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (capture-exit) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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
