Redmark is a javascript work queue with the ability to control how often a job is allowed to run. Jobs are completely independent of each other and can be scheduled at different rates. This allows you to queue up jobs to a service which enforces rate limiting (example: github API v2), running them within the limits of the service and in the order they were received.
FEATURES
- Independent limiting checks for each job
- Customizable frequency options and time resource pool settings
- No outside module dependencies; works right out of the box
- Built in job statistics tracking
REQUIREMENTS
- node.js with ssl (crypto) support
USAGE
Add a job that can run once a second
// Generate the job hash id and setup the limiting options for it
// Limiting options designate this job will run once a second and we only
// allow a maximum of 1 second worth of credits to build up in the pool when
// no jobs are available to run
var jobid = queue.seed(function() {
console.log("Running a job [" + (+new Date()) + "]");
}, {time : 1000, total : 1, max : 1000});
// Add a job of the seeded type to the queue with no data to pass in
queue.add(jobid, []);LICENSE
