Hey, I know that vetur support Intellisense like mentioned here https://vuejs.github.io/vetur/intellisense.html . But it doesn't support for setup yet. Which is used for vue-function-api

Here's the code I tried

<template>
  <div class="home">
    <img alt="Vue logo" src="../assets/logo.png" />
    <HelloWorld msg="Welcome to Your Vue.js + TypeScript App" />
    <div>
      <span>count is {{ count }}</span>
      <span>plusOne is {{ plusOne}}</span>
      <button @click="increment">count++</button>>
    </div>
  </div>
</template>

<script lang="ts">
import Vue from 'vue'
import { value, computed, watch, onMounted } from 'vue-function-api'
import HelloWorld from '@/components/HelloWorld.vue' // @ is an alias to /src

export default Vue.extend({
  setup() {
    const count = value(0)
    const plusOne = computed(() => count.value)

    const increment = () => {
      count.value++
    }

    watch(
      () => count.value * 2,
      val => {
        console.log(`count * 2 is ${val}`)
      }
    )

    onMounted(() => {
      console.log(`mounted`)
    })

    return {
      count,
      plusOne,
      increment
    }
  },
  name: 'home',
  components: {
    HelloWorld
  }
})
</script>

I still don't get the intellisense auto complete for count, plusOne, and increment.

Thanks for developing this extension btw. :)

I guess it's impossible to support vue-function-api because there is no way to extend Vue instance type from plugins. This is known limitation for current Vue's typings. (ref #1226 )
We will be able to support setup and declared properties by it in Vue v3.

Hey there 👋

Would that be possible to add few JSDoc comments to our component to make it works in the meanwhile?

I think that's an outdated issue.
The new @vue/composition-api is work well for me
