After building a simple Plasmic / Gatsby project I realized that the major part of the generated
index.html was just CSS, with a lot of it being unused (according to IntelliJ).
I created a dumb script to remove all unused CSS and it managed to reduce the page size by more than 50% while keeping the same appearance.
[Optimizer] CSS Blocks before: 221 after: 48 [Optimizer] Size before: 48944 after: 20948
So I think it would be great if all this unused CSS was removed. Maybe it is just some configuration to do on Gatsby side, I didn’t search further.
