How do you use Coffeescript global variables when starting a client in Meteor?

Question

As lib.coffeeI have @x = 1. As client.coffeeI have Meteor.subscribe('data', x). When the page loads, I get an error in the console:

Uncaught ReferenceError: x is not defined

However, after the page has finished loading and entering the type xin the console, it is recognized as a global variable with a value of 1.

It is related to the order in which the source files are evaluated. For all the details, carefully read the this section in the docs. You can play a series of games with file names and locations to change the order in which they are downloaded:

• ,
• ,
• , lib

, , , - :

Meteor.startup ->
  Meteor.subscribe 'data', x

Tracker.autorun ->
  if Meteor.userId()
    Meteor.subscribe 'data', x
