    p-break

    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

    pBreak([value])

    Starts the break. Any .then()'s between here and pBreak.end() are skipped.

    value

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

    pBreak.end

    Ends the break. Make sure not to have any other .catch() handlers between pBreak() and here.
