Yes it is pretty straightforward though the project is still growing and suffering from the usual growing pains. Think docs that has plenty of room for improvement, insufficient example projects and components. On the up side the team responds quickly, the concepts are ridiculously simple compared to Redux and there's a burgeoning community around it.

E.g. https://sveltematerialui.com/

The Next.js equivalent for SSR is Sapper: https://sapper.svelte.dev/

Note the creator of Svelte is the same guy who created the Rollup bundler so pretty much everything comes with dual configs for both Rollup and Webpack.
