Break out of a promise chain
See "How do I break out of a promise chain?" for a better way.
$ npm install p-break
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);
//=> '🦄'
Starts the break. Any .then()'s between here and pBreak.end() are skipped.
Value to pass down the chain after pBreak.end().
Ends the break. Make sure not to have any other .catch() handlers between pBreak() and here.
