svelte 5 clone (hopefully)

• Templating syntax: literally svelte, you can even use svelte lsp.
  • you can do interpolation e.g. {count.value}.
  • #if :else :else if
  • one component can contain multiple root nodes like svelte
• Reactivity: i want it to look like svelte but i hate doing transformation so .value it is then.
  • signal behave the same as svelte $state except you need to use .value. (i should say "more like vue" tho)
  • there is also effect and computed
• event listener
• each syntax should be ok now. see each.ts for more technical note.
• value binding for input and textarea
  • auto coerce type to number for <input type="number">
  • the same go for checkbox
• Dynamic attribute class="border {someExpression}" or placeholder={anotherExpression}
• a reactive proxy like vue reactive for deep reactivity
  • we also do array patching.
• pass getter and setter instead of a Signal to a binding
• Component
  • no generated props type becuase im too lazy
  • you can access props via $$props
  • mount(...), #if, #each, #key (not yet implemented) do produce effect scope.
• shorthand props syntax name={name} -> {name}, bind:name={name} -> bind:name
• lifecycle hooks: onMount, onDestroy
• Component instance binding bind:this
  • you cant use export function something(...) syntax yet. for now use $$exports.something = ...
• non dom support with custom renderer

• think about each binding: should we make each item a signal or not.
• parse more complex expression here #each {expression} as something, index
  • #each cats.filter(it => it.id.length < lenght) as cat, i
  • currently, this is parse failure
• Async stuff
  • await block
  • some kind of react-like suspense boundary
  • async derived 💀💀💀
• do transpiling magic that allow you to use signal without .value like runes
• typescript support
  • type definitions of stuff exported form sway is for some reason all gone when used in .sway file. maybe its becuase of svelte lsp
• SSR
  • i need to create a new transformer and maybe a new parser too
  • hydration look like pain in the ass
  • think about vite integration or may be we could offload this to sway/kit lmao
• a router (or sway/kit, beside from ssr thing this look quite fun to make, especially ts magic for PageData)
• realworld (frontend only)
• value binding for select
• scoped style

• :else block under #each
• transition, animation

• packages/sway core framework
  • it export signal primitives
  • there are also sway/compiler and sway/runtime
• packages/vite-plugin-sway vite plugin for .sway template
• playgrounds/development a vite project to experiment with the framework. If you want to try sway you should play around with package.
• playgrounds/server nothing yet
