# Promise-based persistent task queue

_qtask is a persistent queue for a function passed in at creation time that processes data passed at any later time_

Work in progress

## Usage

```js

var request = require('request');

var Queue = require('qtask');

var q = new Queue({

  throttle: 100,

  blockOnFail: true, // prevent next task from running if previous task struck out

  strikes: 3, // defaults to false - never strike out

  process: function(data) {

    // return Q.Promise or a value

    return Q.Promise(function(resolve, reject) {

      request(data.url, function(err, resp, body) {

        if (err) return reject(err);

        else return resolve(resp);

      })

    });

  },

  path: './path/to/queue.db'

});

q.push({

  url: 'http://tradle.io'
