ordered-queue.js

Queue with concurrency that starts tasks in order and runs them in parallel.

Usage

const OrderedQueue = require('ordered-queue');
const q = new OrderedQueue((str, callback) => {
  console.log(str);
  callback();
}, { concurrency: 10 });

q.push(3, 'fox');
q.push(1, 'quick');
q.push(0, 'the');
q.push(2, 'brown');

// Will print:
//
// the
// quick
// brown
// fox
//

API

new OrderedQueue(worker, [options])

Creates a new ordered queue with given worker and concurrency. This inherits from timequeue, so it will have all properties, methods, and events from it. Only the TimeQueue#push() method is rewritten.

OrderedQueue#push(order, args1, arg2, ..., callback)

order must be an integer that determines the order of the task. The callback is optional, will be called once task finishes if provided. All arguments inbetween will be passed to the worker.
