I read the build.js and what I have in mind is different. Im not packing a flow into a standalone app, I'm just optmizing the flow by bundling all its depndencies, and not copying them over to the packaged app. This would result in 1 single dependency, like a huge node package. All code that isn't used would he gone. In node_modules there would exist only a single package, with a single huge minified index.js. The same for index.html, locales, icons, examples assets.
After bundling the flow, I could use your build.js to pack it. There would exist 1 dependency in node_modules.
