Great overview. Small clarification. The section around 14:50 is not about the case where we wait for HTML (or data). It’s about the case where we wait for JS code to load.

Previously it was not possible to start hydrating until *all* JS code has loaded. This made it difficult to integrate SSR and code splitting. (Code splitting is when some code is loaded as a separate script tag to reduce the main bundle size.) The new feature here is we can start hydrating the page before all the JS code for it has loaded. So SSR now doesn’t break code splitting. They work together.

Awesome. Looking forward to what Next Js does with this feature.

This has a lot of potential. Still keeping my www app on React 17 for the time being. Once we have a working deployment in production we will try to implement this in staging.

Can we use React partially? I mean, for most part of the website, we use standard, classic, html, css, js, and only use React on part that requires interactivity, like live feeds, chats, etc.? and possibly lazy-load the React part only?

[sariksiddiqui]

how are they gonna stream the lazy components?Server side events or http2 stream?

Not sure if u said this in the video (im at min 10 actually) but will this improve the seo on a react app?

Cover Vite.js in your videos, if possible.

[DEV_XO]

Does this means we can do the same thing we do on nextjs but actually on a create-react-app? :D

Really liked the idea of suspense with SSR .

I have no idea what he is saying. He has not shown any existing working and a visualization of how the new feature would come into picture. Anyways maybe people like me are not the intended audiences.

He seems like a lazy loader
