Possibility to generate only from vue-files

[mkarras]

First of all: Thank you for your work!

It would be great to configure to generate configs only from vue-files.
When exporting a component via a index.ts file the component is generated twice. For example:

{
  "my-button/label": {
    "type": "string",
    "description": "The label."
  },
  "MyButton/label": {
    "type": "string",
    "description": "The label."
  }
}

my-button/label is generated from the folder (components/my-button/index.ts) and MyButton/label generated from the actual component MyButton.vue.
