Svelte is the premise behind Sapper. If you want to use React, use Next; if you want to use Vue, use Nuxt; if you want that 7kb Hello World (instead of Next's 204kb or Nuxt's 175kb) then you have to adopt a more efficient approach. We're not reinventing HTML, we're using HTML. And CSS. ('Reinventing HTML' is a far more fitting description of JSX, and then there's CSS-in-JS...) Doing so is what allows us to statically analyse your app and compile it to a) a tiny client-side JS payload, and b) an incredibly efficient server-side renderer.
