ReferenceError: require is not defined in ES module scope, you can use import instead

[SwiftWinds]

When using this package with SvelteKit, I get:

ReferenceError: require is not defined in ES module scope, you can use import instead
This file is being treated as an ES module because it has a '.js' file extension and '/Users/matt/Development/ucsb-fake-badge/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.

And it goes away when I remove svelte-persistent-store from my project. Any ideas how to fix this?

From my investigation (see here) I seem that the issue came from the dependency esserializer.

I did some tests, and sadly it appear that I won't be able to fix/do a workaround on my side.

To fix the error change this line https://github.com/MacFJA/svelte-persistent-store/blob/c6ad468a26ba0222679c67cc506e8fd17ef31284/src/index.ts#L2 to this: import * as ESSerializer from "esserializer"

I solved this problem by downgrading to 1.2.0.

Same here.

downgrading to 1.2.0 also worked for me
