That is the point of svelte/sveltekit. It keeps framework details at a bare minimum and adhere as much as possible to web standards so you can write HTML, JS and style your pages with CSS. As in contradiction to ie. React which have it’s own wrappers for simple things like page links (anchor elements).
Javascript would be equal to workflows and states in Bubble, so yes, it requires some effort to learn. But no more than the effort you have to put into an alternative no code service.
When all is said, I still hope Bubble change their pricing plans so we can go on with prototyping and small projects…
Thanks for the discussion. Wishing all the best luck.
