## README

# Promise-Barrier

This barrier returns a Promise and can operate as a pool.

# Interface

    const Barrier = require('promise-barrier')
        , myData = [ '/home/egroat', '/etc/', '/srv' ]
        , poolSize = 2

    function myTask(datum) {
      return new Promise((pass, fail) => {
         // Some async task here,  e.g
         fs.readdir(datum, 'utf8', (err, files) => {
            err ? fail(err) : pass(files)
         })
      })
    }

    // Pool size is optional.  Unspecified it is infinite
    Barrier(myTask, myData, poolSize)
        .then((results) => {
            // Nothing went wrong
            console.log("Correct:", results)
        })
        .catch((data) => {
            // Some failed
            console.log("Correct:", data.results)
            console.error("Failures:", data.errors)
        })
