Question

The error message "Property 'showUserDropdown' is not found on type '{}'.ts" indicates that the specified property is not present in the defined

While creating a basic Vue component, I encountered an error in the IDE regarding the {{ showUserDropdown }} with the message:

Property 'showUserDropdown' does not exist on type '{}'.ts

Despite adding it to data,

<template>
  <div>
    {{ showUserDropdown }}
  </div>
</template>

<script lang="ts">
import { defineComponent } from "vue";

export default defineComponent({
  name: "TheCompanySiteDetailPage",
  expose: [],

  data() {
    return {
      showUserDropdown: false,
    };
  },
});
</script>

I searched online for a solution and found recommendations to use definecomponent, which I have implemented, but the error persists.

typescript vue.js

Here are two solutions to address this inconsistency:

To resolve this issue, you can explicitly type your data using Typed. Begin by creating a file called TheCompanySiteDetailPage.vue.ts and add the following code:

import { defineComponent } from "vue";

type TheCompanySiteDetailPageData = {
  showUserDropdown: boolean;
};

export default defineComponent<TheCompanySiteDetailPageData>({
  name: "TheCompanySiteDetailPage",
  expose: [],

  data() {
    return {
      showUserDropdown: false,
    };
  },
});

An alternative approach is to cast the data type in the template as shown below:

 <template>
   <div>
     {{ (data as TheCompanySiteDetailPageData).showUserDropdown }}
   </div>
 </template>
