What forces layout/reflow. The comprehensive list.

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

Uninstall nodejs from OSX Yosemite
# first:
lsbom -f -l -s -pf /var/db/receipts/org.nodejs.pkg.bom | while read f; do sudo rm /usr/local/${f}; done
sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*
# To recap, the best way (I've found) to completely uninstall node + npm is to do the following:
# go to /usr/local/lib and delete any node and node_modules
cd /usr/local/lib
sudo rm -rf node*

Run NodeJS as a Service on Ubuntu 14.04 LTS

Run NodeJS as a Service on Ubuntu 14.04 LTS

With Node you can write very fast JavaScript programs serverside. It's pretty easy to install Node, code your program, and run it. But > how do you make it run nicely in the background like a true server?

  • Go to /etc/init/
  • $ sudo vim yourapp.conf
  • Paste script.conf
  • $ sudo start yourapp
  • And when you wanna kill the process $ sudo stop yourapp
