Lightning Fast Deployment of Your Rails-backed JavaScript app

on YouTube ↗32m

" summary

Claims deployment time drops from more than five minutes to under fifteen seconds with zero downtime by separating static assets from Rails, uploading fingerprinted JS/CSS to S3 + CloudFront, storing the boot HTML in Redis and serving it via a lightweight controller, using manifest-diff uploads and Rake tasks for differential S3 deploys and deploy JavaScript in <15 seconds. Adds preview-by-manifest-id, injects per-user JSON into the HTML, and enables branch A/B tests (redesign gave ~9% lift).
