Using `querySelector` in TypeScript with Vue 3

Encountered a TypeScript error while using the Vue Composition API

 let myElement = document.querySelectorAll('my-element') 
    

The TS error I'm getting when trying to access it like this: Property '_props' does not exist on type 'Element'.ts

myElement._props.value

let myElement = document.querySelector('my-element') as HTMLElement
    

Answer №1

In preparation for rendering the page, it is important to gather information before the element is actually created. For a better understanding of this concept, refer to the life cycle of Vue3 in the following link: https://vuejs.org/guide/essentials/lifecycle.html Make sure to retrieve the relevant information after the page has been fully rendered.
