This is just a small example of react being rendered by the server in Scala using Nashorn and play.
The main part of the DOM is completely rendered by react on the server.
In the case of no javascript, it accepts form POSTS, otherwise it just uses standard ajax.
You need JDK 8 which has Nashorn included with it.
A browser with the fetch API. I have not included a polyfill for this.
Go to root directory, then:
sbt
run
You can now hit the app on http://locahost:9000/.
Try using it with and without javascript.
