Parallel provide a simple way for management of parrallel async/sync call
Parallel provide a simple but powerful way for management of parallel async call.
Normally we use async or promise for parallel async control. They can resolve every kind of async control problem we get, but the problem is they've done too much and it's neither easy to remember the complicated APIs nor refactoring the code.
Consider chemzqm/serial if you want to control serial callbacks, they have almost the same API.
npm install node-parallel
component install chemzqm/parallel
You must have
component installed for browser usage and
mocha-phantomjs installed for testing.
$ npm install -g component mocha mocha-phantomjs$ git clone firstname.lastname@example.org:chemzqm/parallel.git$ cd parallel && npm install$ make#run test on server side$ make test#run test through phantomjs$ make phantomjs
var parallel = ;var fs = ;
Init new Parallel instance.
Set the timeout to number
ms, default is
Add Function to parallel, the first argument is a callback function, it should be called with
error as first argument and result you need as secound argument.
The callback function is called with
error (null or undefined if not exist) and the result array when all the request get finished (or timeout reached).
Note, this function should only be called once.
