Whether or not JS-SSR with hydration is performant is an interesting topic, but sort of misses the forest for the trees, no? The thread you link to is about a post which speaks about whether that extra level of complexity is even necessary for many use cases (it isn't).

HTML + JQuery, which the hydration approach is compared with, is not used for performance reasons per se. It's used because its easier to reason about and the incremental interactivity that something like JQuery brings to HTML is better than writing your entire frontend in React for something as simple as a blog, for example.

it does not take much complexity to start feeling the pain of jquery-style imperative DOM sync & manip. you don't need to go too far past "simple blog" for this to become obvious.

FWIW, the linked site is built with a 300 line custom build script, Rollup, Buble & Terser - even the dev dependencies are extremely minimal. no, it doesnt have the latest HMR hotness, so the DX could be a bit better if i wanted more bloat.

This kind of progressive enhancement but with the latest JS frontend component models is where Vue shines. Vue 3.0 will be making it even better and faster.

You don't need jquery in most situations unless you are supporting old browsers. Modern js is good enough. At best, you will end up writing a few lines to abstract what jQuery abstracts away from you.

if you still want jquery in 2020 (and that's ok because raw DOM apis still need sugar), for the love of god please use https://umbrellajs.com/ instead.

it's like 1/10th the size, api-compatible and well-architectured.
