Can React project use autosave to change stylish?

[zhangolve]

My project is baseed on React +Node.js+NPM+Router ,when I develope the project ,my project url is : http://localhost:8989/#/ ,I have seen the FAQ of autosave and configed the extension’s options like the screenshot (I am a chinese)

the route address is my project folder.

But I failed to autosave my project?

Can React project use autosave to change stylish?

Or maybe my configution was wrong?
