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

### 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
|
||
|
|
```
