Description

Can we do ssr-ed client component equivalent of https://github.com/vitejs/vite-plugin-react/pull/841? For this, Vite needs to support <link rel="stylesheet" ... /> as initial sheetsMap candidate https://github.com/vitejs/vite/blob/84079a84ad94de4c1ef4f1bdb2ab448ff2c01196/packages/vite/src/client/client.ts#L497-L507

Technically streamed ssr-ed client component can inject <link rel="stylesheet" /> later than csr-ed client component injecting <style ... />, but I guess we can leave that out such edge cases for starter.

Research direction

Start with the referenced Vite client.ts location around lines 497-507 and compare the approach in vite-plugin-react pull request 841. Trace how streamed SSR client components and CSR client components contribute stylesheet candidates during development; done means the SSR stylesheet link is handled as an initial sheetsMap candidate without duplicate CSS injection.
