Storybook option in build process.

What problem does this feature solve?

Hi, storybook is important in development of components. And every time had some issues in versions of packages of vue-loader, storybook/vue. And will be good option to have also it in templates.

Thanks in advance,
Vlad

What does the proposed API look like?

To add storybook in list of options when use cli.

This should be solved by the community with a plugin.

There is already one, in fact: https://github.com/almeynman/vue-cli-plugin-storybook
