Speeding Up Your Front-End: 2016 Version
summary
Rails 5 plus Sprockets 3/4 adds concrete fixes: use manifest.js and index.js modules to control precompile inputs, enable Babel/ES2015 for ES6 files, and serve source maps so dev matches production. Precompile time drops via a cache-path fix (reported as 12x precompile improvement). SRI support generates integrity hashes, Rails adds strong/weak ETags, HTTP cache forever and custom asset headers (Expires), fragment + collection caching uses read_multi with cache: true and collection cache keys, and async/defer recommendations improve page paint.
