paraflow

Paraflow

Run an asynchronous function on (x) number of items in parallel while allowing (x) to change at any time.

var paraflow = require('paraflow');

var jobs = [...];
var p = paraflow(3, jobs, workFunction, function finished(err, results){});

// later bump the number of parallel functions allowed.
p.maxFlow(1)

Includes a simpler wrapper if you have an array of functions to call instead of items. Each function is passed a done(result) callback as the only parameter. When all the done(result) functions are called, the finished callback is called.

var paraflow = require('paraflow');

var jobs = [function(){}, function(){}]
var p = paraflow(3, jobs, function finished(err, results){});
