Just reminder. For maintainability, consider using Vue mixins for subfeature.
For example, you want to add markdown feature on Blog.vue and Comment.vue. You can structure your project by:

.src/ts
├── components
│   ├── Blog.vue
│   └── Comment.vue
│
└── mixins
    └── markdown.ts

then if you want to add markdown feature on some component you just

import markdown from '@mixins/markdown'
export default Vue.extend({
  mixins: [markdown]
})
