There are 4 branches:

master: create-react-app + ssr (now works in both dev and prod modes)

Disadvantages:

• impossible apply changes from client side when starting both ssr and spa
• problem with applying loaders(such as isomorphic-loader)

ssr-with-webpack-watch: custom config + ssr (now works in both dev and prod modes)

webpack --watch with nodemon are used.
Disadvantages:

• impossible apply hot reloading for all files(also for css) when starting both ssr and spa - need to do manual refreshing of browser
  NOTE: but hot reloading works fine when starting only client

ssr-with-custom-config: custom config + ssr (to be implemented)

webpack-dev-middleware and webpack-hot-middleware are used
Disadvantages:

• ...

ssr-with-webpack-approach: webpack libs + ssr (to be implemented..)

webpack-dev-middleware, webpack-hot-middleware and webpack-hot-server-middleware are used.
The main point: extracting chunks from clientStats and injecting them to html file
