A new create-react-app project currently weighs-in at 294Mb with a 293Mb node_modules folder containing 1017 modules. A new Clojurescript Re-frame project, by contrast, totals 72Mb of which node_modules makes up 12Mb containing 23 modules. A bit of a raw deal with CRA, don't you think, considering Re-frame gives you immutability for free and a full complement of built-in Clojurescript functions?
