Meteor.collectionCount

How to use this package

Starting with version 0.0.4 Meteor.CollectionCount is an object that contains all methods. Meteor.collection_count and Meteor.collectionCount are only for backwards compatibility.

Server side

On your server publications, instead of returning the cursor directly, use the new Meteor.CollectionCount.publish method

Function signature

Meteor.CollectionCount.publish(publication, cursor, addIds = false)

Here is an example of a typical publication of a collection

const Items = new Meteor.Collection('items');

Meteor.publish('itemPublication', function(query={}, skip=0){
  const self = this;
  const cursor = Items.find(query, {
     limit:10,
     skip: skip,
     sort:{number:1}
  });
  return Meteor.CollectionCount.publish(self, cursor, true);
});

Client Side

On the client we check with Meteor.CollectionCount.get for our subscription

Template.items.onCreated(function(){
  const instance = this;
  instance.skip = 0;
  instance.subscribe('itemPublication', instance.skip);
  
  instance.autorun(function(){
    const c = Meteor.CollectionCount.get( 'itemPublication' );
    console.log(`items maxCount = ${c?.maxCount}`, c?.ids);
  })
});

In case one publication returns multiple cursors, we can also look for the collection name

 const c = Meteor.CollectionCount.get( 'itemPublication', 'items' );
