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

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

Usage

```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 ```
