Use this.unblock inside Meteor Publications

This is a project to provide this.unblock functionality to publications. this.unblock inside publications is one of most(may be a little bit less) requested feature and but it hasn't been implemented yet!

So, this project implements that feature as a community package thanks to the MeteorX project.

Why unblock?

Meteor executes, DDP messages for a single client in a sequence. So, if one message takes a lot of time to process, that time will add up to all the messages. Luckily, there is an API called this.unblock which can be use inside methods as shown below.

  longMethod: function() {
    Meteor._sleepForMs(1000 * 60 * 60);

So, other messages can start processing without waiting for the above method.

Unfortunately, this is not available for Publications(subscriptions) for no reason. But now you can possible it with this project.


Install following package into your Meteor app.

meteor add meteorhacks:unblock

// for older Meteor versions
mrt add unblock

Use it inside your publications, if that takes too much time or you don't need subscriptions from other publications to wait on this.

Meteor.publish('myLongPublications', function() {
  this.unblock(); //yeah!
  Meteor._sleepForMs(1000 * 60 * 60);
