How can I designate a default value for a variable within a prop in a Vue.Js component?

I have a question regarding setting a default value for a prop using a getter.

props: {
    userID: {
      type: String,
      default: ''
    }
  }

The default value I want to set is obtained through:

computed: {
    ...mapGetters('Auth', ['getId']),

}

Is there a way to make the prop UserID automatically set to the getId value retrieved from the mapGetter?

Answer №1

Utilize the computed property to establish the initial value.

computed: {
  userIdComp() {
    return this.userID ?? this.$store.getters['Auth/getId'];
  }
}

Replace occurrences of userID with userIdComp
