  "readme": "# async-promise-queue\n\n[![Build Status](https://travis-ci.org/stefanpenner/async-promise-queue.svg?branch=master)](https://travis-ci.org/stefanpenner/async-promise-queue)\n\nA wrapper around the `async` module, that provides an improved promise queue.\n\nSome highlights:\n\n* promiseified method (all wired up)\n* in a failure scenario, it will wait for pending work before rejecting. This prevents the run-away work problem.\n\n## Usage\n\n```sh\nnpm install async-promise-queue\n```\n\nor\n\n```sh\nyarn add async-promise-queue\n```\n\n### Debug logging\n\n```\nDEBUG=\"async-promise-queue*\" node <your program>\n```\n\nAnd you will be informed when a queue is used, and what its concurrency becomes (note: we can always add more logging, submit your ideas as pull requests!)\n\n## Example\n\n```js\n'use strict';\n\nconst queue = require('async-promise-queue');\n\nqueue.async // a reference to the `async` module which `async-promise-queue` is requiring.\n\n// the example worker\nconst worker = queue.async.asyncify(function(work) {\n  console.log('work', work.file);\n  return new Promise(resolve => {\n    if (work.file === '/path-2') { throw new Error('/path-2'); }\n    if (work.file === '/path-3') { throw new Error('/path-3'); }\n    setTimeout(resolve, work.duration);\n  });\n});\n\n// the work\nconst work = [\n  { file:'/path-1',  duration: 1000 },\n  { file:'/path-2',  duration: 50 },\n  { file:'/path-3',  duration: 100 },\n  { file:'/path-4',  duration: 50 },\n];\n\n// calling our queue helper\nqueue(worker, work, 3)\n  .catch(reason => console.error(reason))\n  .then(value   => console.log('complete!!', value))\n```\n",
