+[![Build status](https://ci.appveyor.com/api/projects/status/8044m918rwic8b9n/branch/master?svg=true)](https://ci.appveyor.com/project/embercli/capture-exit/branch/master)

+
+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](https://github.com/sindresorhus/ora/issues/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
+```
