Just so it’s here for everyone. I figured out how to get things going with Webpack by following this.
Since whatever bundler either Wappler or Capacitor was using is now deprecated, you have to install another one like Webpack manually
The only thing I would add, is that after you add your platforms (iOS and Android), each time you need to go back into your package.json and switch your “@capacitor/core”: version back to 5.3.0 from 4.6.0 then run npm install in your terminal.
Wappler keeps reverting it to 4.6.0 every time you add a platform.
