The Two Reacts

Post on RSC

The post

Apps always run in two devices, mine and others.
If it runs on mine, i would have client state
Users expect instant feedback (little delay) on interactiosn with buttons, sliders,etc. While they accep the delay on links
When building a UI at least some interactions should have zero latency and network roundtrips
On react, UI is a function of state, meaning the state determines the UI. When it changes, UI must be recomputed thus my computer would recompute it.
On the other hand, when we want to show information about a webpages metadata, the UI is not recomputed, instead, it is computed in the server and streamed to the client. -No more UI depending just on state but also on data.
It seems either we could have UI based on state or based on data, not both
