An upgrade to Storybook 8 with VueCLI/Webpack is not possible due deprecation so we should migrate to Vite asap #7468
It is not listed in the template options when creating a new object.

I tried to move to Storybook8 using Vite, but unfortunately, it reached a point of incompatibility.

It looks like it's possible to add @storybook/vue3-webpack5 and use that instead of Vite, although it is deprecated, I repeat.

I am currently trying to port one by one the configuration. The examples are working correctly after tweaking around.

As a final result of my whole research about Storybook 8, it looks like it's not allowed anymore to use just MDX (flavored markdown) to document components. It is now required to first declare it as SFC (Storybook Format Component), then reference it with custom documentation if needed.

For some reason, the plugins are not added to the configuration with Webpack when added in preview.ts. This has been tested with a clean installation with Vue/vite (only option in CLI) and is rendered.

Installing a new version with @storybook/vue3-webpack5 restricts the issue to the library, returning an issue using documented configuration.
