Bundling component/app to a web-component and specifying Vue constructor parameters

[pstatham-exp]

I have an instance where I would like to bundle an .vue SFC to a web component using the Vue CLI instructions.

However, one of the components in the app has a reference to this.$root.$foobar and because the entry to the bundle is App.vue and not main.js where the new Vue({ foobar}) object is instantiated, $foobar will remain undefined.

Is there a place in the vue.config.js where this can be accomplished or can I do something in the structure of an SFC to define the parameters to be used with the Vue instance when created a web component?
