Creating Living Style Guides to Improve Performance

I recently spoke at JSConf about my experience working with Trulia to create a living style guide. The goal for the project was to improve performance, team velocity, and also to have a more consistent design. It was such a fun project (because their engineers were great to work with) and also successful on all three fronts. Here are some of the metrics for the data-lovers:

  • Their HTML is 48% smaller
  • 21% faster load time
  • 60% faster time to first byte
  • Reduced unused CSS by 135kb
  • Search results page views increased by 11%
  • Property detail page views increased by 3% (this page was not changed, changes on the SRP alone account for this figure)
  • Click throughs, leads, customer satisfaction, and filter use also improved

I’ll be speaking at Velocity Conference in a couple weeks where I’ll go into more detail about the Sass magic that made this possible. :)
