Mobile Server Side Rendering

This year marks the first year that we are doing full scale rendering of our SPA application on our mobile.walmart.com Node.js tier, which has provided a number of challenges that are very different from the mostly IO-bound load of our prior #nodebf.

The infrastructure outlined for last year is the same but our Home, Item and a few other pages are prerendered on the server using fruit-loops and hula-hoop to execute an optimized version of our client-side JavaScript and provide a SEO and first-load friendly version of the site.

To support the additional CPU load concerns as peak, which we hope will be unfounded or mitigated by our work, we have also taken a variety of steps to increase cache lifetimes of the pages that are being served in this manner. In order of their impact:

Underscore.template: Super-simple/-stupid partials. It's quick and dirty yet it does what I want, so there.

// Fetch the template HTML from the DOM, hand it over to `Underscore.template`,
// assign some variables, and set up a `partial` method.
