Hi Allen, YARN-3368 is using Ember.JS and Ember.JS depends on npm (Node.JS Package Manager) to manage packages.
One thing to clarify is: npm dependency is only required by build stage (JS build is stitching source files and renaming variables). After JS build completes, there's no dependency of Node.JS any more. Server such as RM only needs to run a HTTP server to host JS files, and browser will take care of page rendering, just like HDFS/Spark/Mesos UI. There're a couple of other Apache projects are using Ember.JS, such as Tez/Ambari. Ember.JS can help front-end developers easier manage models, pages, events and packages.
