caught

node caught

Doing something like this:

var p = Promise.reject(0);

setTimeout(() => p.catch(e => console.error('caught')), 0);

will generate a lot of helpful warnings:

(node:13548) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): 0
(node:13548) DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
(node:13548) PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

This module lets you write:

var caught = require('caught');

var p = caught(Promise.reject(0));

setTimeout(() => p.catch(e => console.error('caught')), 0);

to avoid those warnings. Use at your own risk.

• Should I refrain from handling Promise rejection asynchronously?

Installation

To use in your projects:

npm install caught --save

Usage

var caught = require('caught');

var p = caught(Promise.reject(0));

Note that it is not the same as writing:

var p = Promise.reject(0).catch(() => {});

which would not return the original promise and wouldn't let you to add catch handlers later.
