Even after migrating to ES modules, jQuery is still somewhat bloated. It is 27 kB (minified + gzipped) [0]. In comparison, Preact is only 4.7 kB [1].
Is there some outlier place where people using virtual DOM frameworks don't also include 100-200kb of "ecosystem" in addition to the framework?
I suppose anything is possible, but I've never actually seen it. I have seen jQuery only sites. You get a lot for ~27kB.
I had started with a simple front-end that was using jQuery to quickly prototype the device controls, but quickly exceeded my goal of keeping the front-end at under 40KB total gzipped. The problem is needing more than just jQuery, we also needed jQueryUI to help with the front-end, or build out similar complex components ourselves. And as soon as the jQuery code became non-trivial, it was clear that Preact made much more sense to use. Our payload is quite a bit smaller yhan the jQuery prototype was.
Which is entirely the issue. Supporting a browser for the 10 users who will update jQuery in 2025 is insane.
