Web Assembly build and build file size

Hello,

I’ve been testing out WASM builds and was curious if there’s any walkthrough docs on setting up and building optimal WASM builds?

I’m also concerned about file size, even with a blank map and all the suggested optimization I can only get the size down to 66 MB.

Has anyone been able to reduce file size significantly more than this?

I’ve followed instructions from these pages:

Thanks!
