> Make unhandled promise rejections fail hard right away instead of the default [silent fail](https://gist.github.com/benjamingr/0237932cee84712951a2)

Promises fail silently if you don't attach a `.catch()` handler.

This module exits the process with an error message right away when an unhandled rejection is encountered.<br>

**Note: That might not be desirable as unhandled rejections can be [handled at a future point in time](https://nodejs.org/api/process.html#process_event_unhandledrejection), although not common. You've been warned.**

Intended for top-level long-running processes like servers, **but not in reusable modules.**<br>

For command-line apps and tests, see [`loud-rejection`](https://github.com/sindresorhus/loud-rejection).

const hardRejection = require('hard-rejection');

const promiseFn = require('some-promise-fn');

Without this module it's more verbose and you might even miss some that will fail silently:

Alternatively to the above, you may simply require `hard-rejection/register` and the handler will be automagically installed for you.

Custom logging function to print the rejected promise. Receives the error stack.
