Purpose: Make Vue's template ref (https://vuejs.org/guide/essentials/template-refs.html) more typescript friendly, make IDE suggestion and compiler validator better

Create a file name useRefs.ts in your utils/helpers directory

import { reactive } from 'vue'

export const useRefs = <T extends object>() => {
  const refs = reactive<T>({} as T)
  const toRef = (refName: keyof T) => (el: any) => ((refs as T)[refName as keyof T] = el)
