# currently-unhandled [](https://travis-ci.org/jamestalmage/currently-unhandled) [](https://coveralls.io/github/jamestalmage/currently-unhandled?branch=master)
> Track the list of currently unhandled promise rejections.
## Install
```
$ npm install --save currently-unhandled
```
## Usage
```js
const currentlyUnhandled = require('currently-unhandled')(); // <- note the invocation
var fooError = new Error('foo');
var p = Promise.reject(new Error('foo'));
// on the next tick - unhandled rejected promise is added to the list:
currentlyUnhandled();
//=> [{promise: p, reason: fooError}]'
p.catch(() => {});
// on the next tick - handled promise is now removed from the list:
currentlyUnhandled();
//=> [];
```
## API
### currentlyUnhandled()
Returns an array of objects with `promise` and `reason` properties representing the rejected promises that currently do not have a rejection handler. The list grows and shrinks as unhandledRejections are published, and later handled.
## Browser Support
This module can be bundled with `browserify`. At time of writing, it will work with native Promises in the Chrome browser only. For best cross-browser support, use `bluebird` instead of native Promise support in browsers.
