@antfu what can we do if we hit

Reached heap limit Allocation failed - JavaScript heap out of memory

in netlify? I enabled SSR to better cache the fast npm request. I mean, we can disable it again 🤔

we should probably at least find out which plugin is using so much memory

let me know if you want any help looking into that on discord
