The standard meteor user subscription does not sync between the client and server

Question

The standard meteor user subscription does not sync between the client and server

I've been experimenting with meteor 7.1.1 and just need a sanity check,

So basically..

if (Meteor.isServer) {
  console.log("Count Server No: "+ Meteor.users.find().count());
  Meteor.publish("directory", function () {
    return Meteor.users.find();
  });
}
// the server side result is Count Server No: 1

if (Meteor.isClient) {
  Meteor.subscribe("directory");
  console.log("Count Client No: " + Meteor.users.find().count());
}
// the client returns Count Client No: 0

I've come across various tutorials and other options, but it seems like there are different ways to achieve this. If anyone could point out the most efficient method, I would be extremely grateful. PS Hope this information helps someone else.

Answer №1

When a subscription is made, the collections on the client and server do not synchronize immediately. Instead, they are synchronized asynchronously in the background. The subscription objects come with a function called ready(), which will return true once the initial batch of data has been sent to the client.

In addition, a subscription can have callbacks defined for the onReady and onError events. For instance, if you only provide an onReady handler like this:

Meteor.subscribe("directory", function () { 
    alert('Count = ' + Meteor.users.find().count());
});

You should see the correct number of users displayed.
