CSR with prerendering and the page model API / SDK

Hi,

I am interested in SSR with rehydration (The server prerenders pages, but the full app is also booted on the client ) in combination with headless Bloomreach CMS ( and the SPA SDK and pagemodel API ).

Could you please share your experience with regards to the following aspects:

  • Search Engine Optimalization ( How much faster is the Full Content Paint (FCP) than Client side rendering (CSR) ) ?
  • Usability ( Is the TTI ( Time to interact ) faster than CSR ) ?
  • How can the application scale with the number of requests ( more “node.js” nodes or “node.js” nodes with more resources )

best regards,
Michiel Rop
