Svelte 4 compatibility

[ktecho]

After upgrading to Svelte 4, Typescript 5, Vite 5, I'm getting this error:

SyntaxError: [vite] Named export 'Swap' not found. The requested module 'sortablejs' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'sortablejs';
const {MultiDrag, Swap} = pkg;

So I guess some small changes are needed in the way that sortablejs is used?

[ktecho]

If I change this in file SortableList.svelte:

import Sortable, { MultiDrag, Swap } from 'sortablejs';

to this:

import Sortable from 'sortablejs';
const {MultiDrag, Swap} = Sortable;

It works perfectly.

@jhubbardsf Can you confirm if the project is unmaintained?

[SikandarJODD]

yes i think so

[harshit-git]

@ktecho found any fix?

@ktecho found any fix?

When I build the app, it works as it is. But in my development environment, I have to make the change from comment
2.

Either @jhubbardsf releases a new version with this change, or you have to do it by hand. Someone could also fork the project, do the change and release a new version.
