Ionic and Capacitor 3 - How to reduce app size and delete unused libs and resources?

hello!
I have a question regarding the app optimization:
There is a simple way for reducing the size of my apps and detect if I have unused libraries and resources?

Or, if you have any suggestion for optimize the final packages.

Thank you!

I would expect this is a job for whatever bundler you’re using. For instance, if your project uses Angular, webpack deals with all of this for you.

thank you for your reply,
yes i’m using Angular,

thanks!
