Supporting both Vue 2 and Vue 3

[noynek]

I'm wondering if it's possible to make my Storybook design system work across both a Vue 2 and a Vue 3 app.
To clarify, I have 3 projects:

1. Storybook design system built on Vue 2
2. Legacy Vue 2 app that imports the design system
3. New Vue 3 app

The issue is that I couldn't convert the Vue 2 app to Vue due to the scale and complexity so I'm developing a new Vue 3 app in parallel. However, I want to use the existing design system components across both apps. It doesn't look like this is possible, but I'm wondering if anyone has ideas.

When I import my design system into a Vue 3 project I get the following Vite error:

   Uncaught SyntaxError: The requested module '/node_modules/.vite/deps/vue.js?v=8e5a9553' does not provide an export  named 'default'
