Why this matters for the Core Web Vitals, and where to start fixing it

A JavaScript framework moves work onto the visitor's main thread. Hydration is the toll: the server-rendered HTML arrives fast, then the framework rebuilds its component tree in the browser before interactions fully work. That window is where frameworks pay INP.

The rendering mode decides the bill. Static or server-rendered output with islands of interactivity costs little. Full client-side rendering makes every visitor's device build the page from scratch. The framework pages compare them on field data.

How does this affect the Core Web Vitals?

JS framework correlates with the CLS. With React, 92% of sites pass the CLS. With Angular, 58% do. The causal link is weak: the choice mostly marks what kind of site made it.
