Break out of a promise chain

See "How do I break out of a promise chain?" for a better way.

Install

$ npm install p-break

Usage

Here the onlyRunConditional promises are skipped if conditional is falsy:

import pBreak from 'p-break';

alwaysRun1()
	.then(() => alwaysRun2())
	.then(conditional => conditional || pBreak('🦄'))
	.then(() => onlyRunConditional1())
	.then(() => onlyRunConditional2())
	.then(() => onlyRunConditional3())
	.then(() => onlyRunConditional4())
	.catch(pBreak.end)
	.then(console.log);
	//=> '🦄'

API

Value to pass down the chain after pBreak.end().
