The Vue3 property 'x' is not recognized on type 'Function' as a global property

I have encountered a strange issue with my Quasar app. I am attempting to define a global variable that consists of metadata about the application in an object format. Despite successfully compiling the app and displaying the correct information on the HTML, I am receiving an error in VSCode.

The problem seems to be originating from src/boot/BackChat.js file. Below is the snippet of code:

import { boot } from 'quasar/wrappers';

const version = '0.0.0';

const backChat = {
  version
};

export default boot(({ app, router, store }) => {
  app.config.globalProperties.backChat = backChat;
});

In Login.vue file, here is another snippet of code:

// ...
<script>
import { ref } from 'vue';

export default {
  data() {
    return {
      backChat: this.backChat
    };
  }
}
</script>

Upon further investigation, it appears that there might be an issue with how I am utilizing this interface or it could potentially be a bug related to Vue file validation. It seems like the validator believes that "backChat" in Login.vue is actually a function. When switching the data() method to mounted(), the function error disappears but then I lose access to it in the DOM. As a newcomer to Vue, I find myself puzzled by this behavior.

Answer №1

Here's a quick workaround that I found to be the simplest solution. It may not be the conventional way of doing it, but since I thought it was a function, I turned globalProperty into a function that returns the object.

Check out src/boot/BackChat.js

// ...
export default boot(({ app, router, store }) => {
  app.config.globalProperties.$backChat = () => backChat;
});

And in Login.vue

// ...
data() {
    return {
      username,
      password,
      backChat: this.$backChat()
    };
},

This simple solution resolved the error in the Vue file and allows for seamless use of the global object.
