Inheritance between vue components

want a function that inherits the parent class, calls public methods, and gets common parameters

first navigate to a specific component Page.vue based on a type

<template>
 <div>
   
   <component :is="page"></component>
</div>
</template>

<script>
import AddPage from "./AddPage"
export default {
  name: "Page",
  props: [],
  data () {
    return {
      page: "AddPage"
    }
  },
  components: {
    AddPage
  },
  mounted () {

  }
}
</script>

then there is a base class Base.vue

<template>
 <div>
   base
</div>
</template>

<script>
export default {
  name: "Base",
  props: [],
  data () {
    return {

    }
  },
  methods: {
    save () {
      console.log("b save")
    }
  },
  mounted () {
    console.log("base mounted")
  }
}
</script>

then my implementation class AddPage.vue

<template>
 <div>
   add
</div>
</template>

<script>

import Base from "Base"

export default {
  name: "AddPage",
  extends: Base,
  props: [],
  data () {
    return {

    }
  },
  mounted () {
    console.log("add mounted")
  }
}
</script>

is there a problem with using extends inheritance in this way? The error in my execution is as follows

found in

-> < Page > at src/page/Page.vue
