Vue 3 — Refs and Edge Cases

Vue 3 — Refs and Edge Cases

Forcing updates, one-off rendering, and refs.Sometimes we may need to directly access the DOM

Vue 3 is in beta and it’s subject to change.

Vue 3 is the up and coming version of Vue front end framework.

It builds on the popularity and ease of use of Vue 2.

In this article, we’ll look at how to use template refs and edge cases with Vue 3.

Template refs

Sometimes we may need to directly access the DOM.

To let us do that, we can assign a ref to the DOM element we want to access and then we can access it in our component code.

For example, we can write:

<!DOCTYPE html>
<html lang="en">
    <script src="[email protected]t"></script>
    <div id="app">
      <input ref="input" />
      const app = Vue.createApp({
        methods: {
          focusInput() {
        mounted() {

to focus an input when the Vue instance mounts.

We assigned the input ref to our input.

Then we called focus on it to focus on the input.

We can also add a ref to component itself and use that to call focusInput .
