Vue Js allow you to define a custom directive that can be used to make code reusable in components. To automatically set focus on input in Vue Js you can define the following custom directive. How this work is that the element will autofocus using the native Java Script "focus()" method behind the scene.
<template>
<input
v-auto-focus
type="email"
placeholder="Your full name"
>
</template>
<script>
Vue.directive('auto-focus', {
inserted: el => el.focus()
})
</script>
