From Meteor's documentation:

In Meteor, your server code runs in a single thread per request, not in the asynchronous callback style typical of Node. We find the linear execution model a better fit for the typical server code in a Meteor application.

This guide serves as a mini-tour of tools, trix and patterns that can be used to run async code in Meteor.

Basic async

Sometimes we need to run async code in Meteor.methods. For this we create a Future to block until the async code has finished. This pattern can be seen all over Meteor's own codebase:

require 'spec_helper'

feature "Login" do
  scenario "remembered user" do
    password = "12345678"
    user = create(:user, password: password)
    
    access_protected_page_should_ask_to_login
    current_path.should eq login_path

Getting started with Meteor

Last weekend I finally got around to building something with Meteor and what follows is a short description of my experience with the platform with a few take aways.

#Heroku, Ruby on Rails and PhantomJS

In this post, I’m going to show you how to modify an existing Ruby on Rails app running on Heroku’s Cedar stack to use PhantomJS for screen scraping. If you’ve never heard of PhantomJS, it’s a command-line WebKit-based browser (that supports JavaScript, cookies, etc.).

Let’s get started. This is a high-level overview of the required steps:

• Modify your app to use multiple Heroku buildpacks.
• Extend your app to use both the Ruby as well as the PhantomJS buildpacks.
• Confirm that everything worked.
