vue-announcer

Imagine browsing pages (routes), receiving alerts and notifications, having a countdown timer on the page, a progress bar or a loading, among others. Now imagine all this happening to people who have visual disabilities and who use screen readers.

The idea of this plugin is to tell the screen reader what is happening and primarily if you use single-page application.
Inspired by others in the community like:

Install package

NPM

 npm install -S vue-announcer

Yarn

 yarn add vue-announcer

How to use

In your main.js

 import Vue from 'vue'
import VueAnnouncer from 'vue-announcer'

Vue.use(VueAnnouncer)

In your App.vue
Example using vue-toasted

<template>
  <div id="app">
    <vue-announcer />

    <h2>App page</h2>
    
    <button type="button" data-va="toasted" @click="notify">
      trigger notification
    </button>
  </div>
</template>
<script>
export default {
  name: 'app'
  methods: {
    notify () {
      let message = `Hi, it's a toasted notification`
      this.$toasted.success(message)
      this.$announcer.set(message) // Sets the message that will be read by the screen reader automatically.
    }
  }
}
</script>

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.

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

Vue.use(VueAnnouncer, {}, router) 

Options

Example:

 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) {
    this.$announcer.setComplementRoute(translations.complementRouteKey /* = 'ha cargado' */)
  }
}

Custom message to each page (optional)

You can set a property on the meta object, which will serve as information to get the message that will be announced to the screen reader on each page. e.g.:

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

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

 Página de inicio ha cargado

Note:

• The plugin checks whether it was defined in the meta object, otherwise, without any problems, the title of the page being loaded will be used.
• The vue-announcer uses the global after hooks router.afterEach to announce the route changes.
