dynamic html generation problem with webpack 3

really appreciate your efforts and the information given within course. love it.

i followed course and wanted to use it in my react app whereas I used all `latest` perhaps except webpack, currently I am using webpack 3. did some minor changes in webpack config you mentioned earlier.
however strange thing is going on with injecting the it injects the <script src="bundle.js"/>`

` "/seasons" => nothing is injected`

not sure what is the reason, i thought maybe React-Router 4.0 is failing but I think it is actually from configuration things to do with `HtmlWebpackPlugin`. Since `bundle.js` not being injected.

Earlier I used in my old application two separate template files( dev, prod) so in production one i can do code splitting

please can you give me hand to identify my problem. for now I get back to my old configuration.
the video only shows generic configuration without putting React maybe i am doing something wrong.
