hard-rejection

Make unhandled promise rejections fail hard right away instead of the default silent fail

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.
Note: That might not be desirable as unhandled rejections can be handled at a future point in time, although not common. You've been warned.

Intended for top-level long-running processes like servers, but not in reusable modules.
For command-line apps and tests, see loud-rejection.

Install

$ npm install hard-rejection

Usage

const hardRejection = require('hard-rejection');
const promiseFunction = require('some-promise-fn');

// Install the handler
hardRejection();

promiseFunction();

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

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

function error(error) {
	console.error(error.stack);
	process.exit(1);
}

promiseFunction().catch(error);

Register script

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

This is handy for ES2015 imports:

import 'hard-rejection/register';

API

hardRejection([log])

log

Type: Function
Default: console.error

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