[Vuejs]-Nuxt.js/Vue.js resuable modal

Since you already defined slots in your component you can pass data to it via slots. E.g.

<your-modal-component>
  <template slot="modal__header">
    header bla bla a
  </template>
  <template slot="modal__body">
    body anything here like <p> hehe</p>
  </template>
</your-modal-component>
