# Announce route changes

For page changes (routes) to be announced automatically, you only need to pass the router object as a parameter at the time of installation.

# Install

import Vue from 'vue'
import router from './router'
import VueAnnouncer from '@vue-a11y/announcer'

Vue.use(VueAnnouncer, {}, router) 

# Options

Key Data Type default
politeness String polite
complementRoute String has loaded


Vue.use(VueAnnouncer, {
  complementRoute: 'ha cargado' // e.g. in spanish
}, router) 

# Methods

Note: These methods are registered on the $announcer property injected into the Vue instance

# $announcer.setComplementRoute(complementRoute)

If you need to set the complementRoute option dynamically without reloading the application, for example if you're dynamically loading translations, you can use this method to update it.

export default {
  onTranslationsUpdated (translations) {
    /* 'Foi carregada' e.g. in portuguese */

# Custom announcer (object meta)

You can customize the message by defining the announcer on the "meta" object for each specific route.

  name: 'home',
  path: '/',
  component: Home,
  meta: {
    announcer: {
      message: 'Página de inicio se'

When the page loads, the screen reader user will hear:

Página de inicio se ha cargado

In the "meta" object you can also modify the route complement and also the politeness settings.

# Announcer in object meta

Key Data Type data default
message String document.title
politeness String polite, assertive, off polite
skip Boolean false
complementRoute String has loaded or set at installation


  • The plug-in checks whether the message to be announced has been defined in the meta.announcer object, otherwise the document title to be loaded will be announced.
  • The @vue-a11y/announcer uses the global after hooks router.afterEach to announce the route changes.

# Skip in specific route

Necessary for dynamic content pages that require asynchronous data to compose the page title.

The skip property on the meta.announcer object is used to skip the automatic announcement made on the router.afterEach, that way you can announce when the asynchronous data is available.

For example:

In you routes.js

  name: 'post',
  path: '/posts/:id',
  component: Post,
  meta: {
    announcer: {
      skip: true

See this example:
Example link, opens in a new window

In you Post.vue

    <template v-show="post.id">
      <h2>{{ post.title }}</h2>
      <p>{{ post.body }}</p>
    <template v-show="error">
      <h2 class="msg-error">
        {{ error }}

export default {
  name: 'Post',
  data () {
    return {
      post: {},
      error: null
  created () {
      .then(res => {
        if (!res.ok) throw Error(res.statusText || 'Error loading the post')
        return res.json()
      .then(res => {
        this.post = { ...res }
        this.$announcer.set(`${this.post.title} has loaded`)
      .catch(e => {
        this.error = e.message
        this.$announcer.set(this.error, 'assertive')
