Getting started with Sapper and Svelte
A friend of mine introduced me to Svelte and the approach impressed me. Instead of doing a lot of work in the browser inside a virtual DOM (like a lot of frameworks), Svelte is a compiler step, meaning the code is compiled to efficient vanilla JavaScript when the project is built. It results in a considerably lighter load whilst also being able to leverage useful functionality such as reactivity which might be why you're choosing to use a framework in the first place. I combined this with Sapper - since retired in favour of SvelteKit - to get a lightweight, statically generated application out of the box.
