CLI-generated app dev-version doesn't update when I change code in /src

I built a Framework7 PWA+Cordova app using the CLI for React. I run the dev server using npm start, but when I change the code (in home.jsx for instance), the app doesn’t update in the browser. However, when I build the app using npm run build-dev, the code updates. Can anyone tell me why the dev version doesn’t work right out of the box?

Yea I also see this same issue . build vue app using the cli … and run > npm run dev , and on editing source code the server does does not update … ( this was working in a lower version of framework7 , i have this issue on v 6 / latest )
