Svelte + SvelteKit

According to the Bun blog and changelog, Bun now supports SvelteKit! Bun is an incredibly fast JavaScript runtime, bundler, transpiler, and package manager — all in one. Similar to using npm, here’s how you can start a SvelteKit project with Bun:

$ bunx create-svelte my-app

I'm experienced with React and was just trying out a small Svelte to-do list to get my feet wet with Svelte and see if it's something I'd like to suggest we try out at work.

However, there's one thing I wanted to clarify that wasn't immediately obvious from the documentation (and to just kickstart some discussion since this community is a little quiet).

In React, if I have a large file doing a good amount of logic, like in the to-list example where I have add logic, remove logic, and toggle logic, all of which can be complex in their own ways if you improve them enough, I am able to extract the logic out into it's own file by creating a custom hook. Like so

const useTodoList = () => {
  const [list, setList] = useState([]);

  const addItem = (taskName) => {
    // task creation logic
    setList(l => [...l, newTask]);
  }

  // logic for removeItem and toggleItem

  return { list, addItem, removeItem, toggleItem };
}

Then, I can bring that into my component file by simply doing const { ... } = useTodoList(); and everything should just work. What would the equivalent be in Svelte? It sounds like I would want to leverage the store concept, but that feels odd to me. I go from having pretty simple logic to having to add additional libraries to my logic. It's a lot of overhead for what should really be a pretty straightforward refactor in React.

Any insight you guys can give would be great! Additionally, I'd love to be able to move the style as well, but so far haven't found anything that would be suitable for that quite yet. Svelte seems pretty set on having one large file whenever possible.

The official interactive tutorial was the way I initially learned Svelte, and it's seen some highly-impressive improvements over the past year. Perfect place to start if you're curious about Svelte!

The Svelte documentation is first class; it really stands out as an example of how technical documentation can be made accessible. However, for a simple and straightforward introduction to build a simple project with Svelte, the MDN Getting Started with Svelte is an excellent guide.
