Fuery

A pausable function queue with optional parallel concurrency

Install

$ npm install fuery

Examples

Create a Fuery instance

var Fuery = require('fuery'),
    queue = new Fuery();

// Allow only 1 function to run at a time (default is unlimited)
queue.limit = 1;

Queue a function

The first argument is a function that you should call when the function has completed.

queue.add(function(done) {
    // Do stuff
    done();
});

You can also add your own arguments like this

queue.add(function(done, x, y, z) {
    // Do stuff
    done();
}, [x, y, z]);

Set context

You can set the context the queued functions run in. When not set, the context defaults to null.

queue.setContext({test: 1});

Start the queue

New Fuery instances are paused upon creation, they always need to be started

queue.start();

Pause the queue

Pausing the queue is also possible, ofcourse. You can supply a callback that will fire when all currently running functions have ended.

queue.pause(function() {
    // All running functions are done
});
