    p-series

    Run promise-returning & async functions in series

    Note: You can just use await in a for-loop to get the same behavior. This package was useful before async/await existed.

    If you're doing the same work in each function, use p-each-series instead.

    See p-all for a concurrent counterpart.

    Install

    $ npm install p-series
    

    Usage

    import pSeries from 'p-series';
    import got from 'got';
    
    const tasks = [
    	() => got('https://sindresorhus.com'),
    	() => checkSomething(),
    	() => doSomethingElse()
    ];
    
    console.log(await pSeries(tasks));

    API

    pSeries(tasks)

    Returns a Promise that is fulfilled when all promises returned from calling the functions in tasks are fulfilled, or rejects if any of the promises reject. The fulfilled value is an Array of the fulfilled values.

    tasks

    Type: Iterable<Function>

    Functions are expected to return a value. If a Promise is returned, it's awaited before continuing with the next task.
