Problem when using Vue.extend to export component definitions

[padcom]

Currently when using TypeScript to get good VS Code support for single file components instead of

export default { }

one needs to use

import Vue from 'vue'
export default Vue.extend({ ... })

This currently leads to the following error:

[Vue warn]: Failed to mount component: template or render function not defined.

How can I fix this?

You have to export an object as single file component
