What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

First off, props to robmoggach for creating a script that attempts to do the job, however I'm working on a Meteor app that requires Mongo and found that the script wasn't setting everything up to completion. Here's an attempt to catalog all the steps I performed, in the hopes it might save someone a bit of headache someday:

1. Use the WebFaction web dashboard to provision your app directories

• Log in, go to Domains/Websites > Applications, click to add a new application
• Name this one for your Meteor app (for the rest of this doc let's use myapp as your moniker), e.g. myappmeteor
• Change the app category to Custom, type to Custom websockets app (listening on port), check to open a port in the firewall
• Save and note the port number you get (let's say it's 20000, you'll need this later)
• Click to add a second application
• Name this one for the Mong

if [ "$(whoami)" != "root" ]
then
    echo "Sorry, you are not root. Use sudo!"
    exit 1
