(more docs TK) the general idea here is that in order to code split and use SSR at the same time, we need to take advantage of webpack's multi-compiler mode, which webpacker doesn't support out of the box
rails new --webpack=react --skip-turbolinks app
bundle add react-rails
bundle exec rails generate react:install
yarn add @loadable/component @loadable/server
yarn add -D @loadable/babel-plugin @loadable/webpack-plugin
run ./bin/webpack at least once before running bundle exec rails s
- Multi-compiler Webpack config: config/webpack/environment.js
- Custom server renderer: config/initializers/react.rb and app/javascript/packs/server_rendering.js
