The JS ecosystem’s penchant for giving you small components that you have to choose individually and then glue together can get a little exhausting. Hopefully the library whose approach you prefer has decent documentation, keeps up with changes to svelte, doesn’t get abandoned, etc.
Edit: apparently Sapper is a Next.js like framework that provides all the components you need for svelte in one package. Someone else said on this thread it’s eventually getting deprecated by the svelte team’s own thing called SvelteKit. Not ideal, but at least they’re working on something more integrated.
