Even though it's not out of beta yet, I feel really productive using SvelteKit. It's the first framework that I've used in 15 years of programming and said "Ahh, finally". I use it in production and am going to release a SaaS starter kit for other folks to use so they don't have to build all the same features every app needs: https://sveltesaas.com/

If you'll indulge me as I wax poetic: Things I like about SvelteKit: none of the front-end/back-end plumbing you usually need to do with JS/HTML/CSS, can use JS/TS throughout the entire stack, filesystem-based routing is so easy to use and maintain, performant and SEO-optimized server-rendered routes with automatic client-side hydration, optional client-side routing for optimal performance, can specify statically-generated pages per route (marketing site and app are all part of one bundle), super fast dev experience.

And Svelte itself is awesome too: Svelte components run super fast (no virtual DOM), have tiny build sizes, stellar interactive documentation, and the developer experience is fire. Svelte was also just voted the #1 most loved web framework in the 2021 Stack Overflow developer survey (it beat out React, Rails, Django, Spring, Laravel, etc): https://insights.stackoverflow.com/survey/2021#section-most-...
