![Coverage Status](https://coveralls.io/repos/sindresorhus/loud-rejection/badge.svg?branch=master&service=github)
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 it in top-level things like tests, CLI tools, apps, etc, but not in reusable modules.
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';
