Is there a way to watch a change of the i18n's current locale?

Question

How can I call a function when the language/locale changes while using i18n?
Should I use Vuex or does vue-i18n has a method that allows me to do that?

Answer 1

You could watch $i18n.locale for any changes but usually, you do change this kind of thing. What is your use-case for such need ?

watch: {
  '$i18n.locale': function(newVal, oldVal) {
    console.log('locale change', newVal)
  }
}
