Promise-break NPM

promise-break

Break out of a promise chain

This is an experiment. I personally wouldn't recommend this. Feedback wanted on the issue tracker.

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

Install

$ npm install --save promise-break

Usage

Here the onlyRunConditional promises are skipped if conditional is falsy:

const pBreak = require('promise-break');

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