Thanks for the feedback. Given that this is a Single Page Application built in React, what would you expect to see? Just some sort of messaging that says javascript is required? I have never considered/tried to handle this problem before so i dont know what is best.

maybe i should create alternative on withoutjs.org without js but i don't know is it worth.
