currently-unhandled 
Track the list of currently unhandled promise rejections.
Install
$ npm install --save currently-unhandled
Usage
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.
