An Illustrated Guide to Ember
summary
Ember application for school finance displays thousands of rows in a semantic table; Ember 1.6 uses metamorph script tags causing rendering to take 6 seconds to 1–2 seconds for small page sizes. Upgrading to Ember 1.8 with HTMLBars rendering engine replaces string fragments with DOM nodes and renders about four times as many rows, cutting latency. Stack uses Rails API, Ember Data and CoffeeScript, then moves from pagination hacks to a stateful redesign with infinite scroll; deployed to districts and handling real load.
