loud-rejection

Make unhandled promise rejections fail loudly instead of the default silent fail

By default, promises fail silently if you don't attach a .catch() handler to them.

Use this in top-level things like tests, CLI tools, apps, etc, but not in reusable modules.
Not needed in the browser as unhandled promises are shown in the console.

Install

$ npm install --save loud-rejection

Usage

const loudRejection = require('loud-rejection');
const promiseFn = require('promise-fn');
// Install the unhandledRejection listeners
loudRejection();
promiseFn();

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

const promiseFn = require('promise-fn');
function error(err) {
console.error(err.stack);
process.exit(1);
}
promiseFn().catch(error);

Register script

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

This is handy for ES2015 imports:

import 'loud-rejection/register';

API

loudRejection([log])

log

Type: Function
Default: console.error

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