How can I ensure a function only runs after all imports have been successfully loaded in Vue 3?

Encountering an issue with importing a large quantitative variable in Vue 3. Upon running onMounted, it seems that the import process is not yet complete, resulting in an error indicating that the variable tesvar is "uninitialized". The code snippet provided below showcases the problem; note that the variable in question is a sizable object that requires some time to load (simply reducing the size of the variable is not a viable solution).

<script lang="ts" setup>
import { onMounted } from "vue"; //This line works fine
import testvar from "../main"; //The correct location for importing the variable

onMounted(() => { //Execution occurs without errors
  console.log(testvar); 
  // Throws error: "Uncaught ReferenceError: Cannot access 'testvar' before initialization"
}

</script>

Answer №1

After seeking assistance from another source, I was able to discover the solution. The issue stemmed from a circular dependency in my main file causing an error. To resolve this, I relocated testvar to a separate typescript file.
