您可能对 Meteor job-collection 感兴趣包(不特定于 angle-meteor):

A persistent and reactive job queue for Meteor, supporting distributed workers that can run anywhere.

job-collection is a powerful and easy to use job manager designed and built for Meteor.js.

It solves the following problems (and more):

• Schedule jobs to run (and repeat) in the future, persisting across server restarts
• […]

特别是job.after(someTimeBeforeAppointment)

// Server
var myJobs = JobCollection('myJobQueue');

// Start the myJobs queue running
myJobs.startJobServer();


// Create a Job (e.g. in a Meteor method)
var job = new Job(myJobs, 'jobType', jobData);

// Specify when it can run and save it.
job.after(someTimeBeforeAppointment).save();


// Server (or could be a different server!)
// How jobs should be processed.
myJobs.processJobs('jobType', function (job, done) {
    var jobData = job.data;

    // Do something… could be asynchronous.
    job.done(); // or job.fail();

    // Call done when work on this job has finished.
    done();
});

可以在 processJobs options 中指定 pollInterval 。默认为每 5 秒一次。
