You can run the webapp locally with `yarn dev`. If you enter the IP of your ESP in the `vite.user.ts` beforehand (template can be found in `vite.config.ts`), all api requests will even be proxied to the real ESP. Then you can develop the webapp as if it were running directly on the ESP. The `yarn dev` also supports hot reload, i.e. as soon as you save a vue file, it is automatically reloaded in the browser.
