Discussion on: Svelte for Sites, React for Apps

So, I appreciate all your stats but your really missing the point.

Svelte is not smaller than Alpine. Take a standard marketing site where the header is just links. Nothing dynamic. These are still svelte components that have Javascript. But it should just be HTML.

I have a Sapper/Svelte site in production that is 126 components, but the number of those components that actually need to be dynamic on the client is less than a dozen.

And none of them have realistic performance concerns that I could not swap it out to Alpine and have the same experience for the user.

BTW Svelte and Alpine both modify the DOM and not a shadow DOM. So performance characteristics would be similar, which the exception of startup, where alpine has the parse live instead of having a JS bundle.

Tree shaking argument is mute, since Alpine is a actual library. Your not tree shaking your code. Your code is in HTML in most cases. You get too complex, use a library for a App. My argument was just simple marketing sites.

Yeah you are right it's deeper than that. If we aren't doing the same work they arent going to be close. Which makes Elderjs interesting since it potentially could. But that also suggests JS on the server. So it isn't a swap in. But it is interesting such an approach could ship less JS. If Svelte itself is smaller and us only hydrating the necessary components.

That would be my happy place, if we could declare what should actually be convert to a live component, vs what should be static html and is just using the life cycle to render, with a dapper framework or something similar.

I'm fairly confident this direction is viable given Marko has been doing this at eBay since 2013. Who it is viable for is a different question. It will be interesting to see more libraries take this approach.
