Did you try create_react_app? I find it way easier to setup my frontend using it than to use webpacker, even being used to both rails and react. You type "yarn build", and you have properly fingerprinted js and css files ready to use, with an `index.html` file that includes them. It's great to only focus on backend in rails, and it brings all the cool thing from js dev for free: babel, webpack, yarn, live reload, import of css files, etc. SSR is indeed still a problem (I've build a cache system that will render pages with chrome headless, for that), but gladly, it's about to be solved (at least for the SEO part): https://webmasters.googleblog.com/2017/12/rendering-ajax-crawling-pages.html https://webmasters.googleblog.com/2017/12/rendering-ajax-cra... The biggest problem yet to be solved: properly handling 404 status.
