Im trying to get next js to load properly with a transpiled styled components component library. Here is a simple repo for reproducing the problem: https://github.com/vongohren/fouc-example
So what happens is that I have a small app that renders the components, but it does not showcase the style on the SSR request, only when the client has been loaded.
Im trying all cases where I do the loading inside the document: https://github.com/zeit/next.js/blob/canary/examples/with-styled-components/pages/_document.js
But it is not able to catch the css from the components. Only the components built in the SSR function itself, and not the components I import.
How can I debug this and figure out how the CSS can be attached on the SSR request as well, and not just the loading of the JS.
I was able to get something to work when using https://github.com/callstack/linaria in the components library, because that outputs a CSS file, I was able to import and add to the SSR rendering. But how can I approach this with styled-components?
