I need to convert at least small part of existing RoR + React + Redux app to React on Rails with Server Side rendering for measure performance and effort.
Already made setup from this tutorial shakacode/react_on_rails_demo_ssr_hmr (previous version). And SSR is working for HelloWorld. But how to pull out needed component and make it work with SSR is a tough call. Following this tutorial with my is no help I a different errors all way long. I tried to render component from my app on /hello_world page from tutorial (with all steps with registering component for SSR) but got this:
Field 'browser' doesn't contain a valid alias configuration
using description file: /app/package.json (relative path: ./app/frontend/folder/my_component_server.js)
no extension
Field 'browser' doesn't contain a valid alias configuration
Also markup could be confusing because React on Rails needs declared component in .erb template, while I already included React app as following in my haml file:
%div#root <-- here is attaching react app
= stylesheet_pack_tag "fonts", "styles"
= javascript_pack_tag "my_react_app_entry_point"
