A guide to easily deconstructing props in a Vuejs template

In Vuejs How to destructure props and improve code readability

I understand that with v-for="({y}) in x" we can destructure, but in this particular scenario there is no v-for

<template>
<div>{{candidate.gender.gender.gender_name}}</div>
<div>{{candidate.name.first_name}}</div>
</template>
<script>
import { mapGetters, mapActions } from "vuex";
export default {
  name: "Candidate",
  props: {
    candidate: Object
  },
  computed: {}
</script>

Is it possible to destructure and use just {{gender_name}} instead of {{candidate.gender.gender.gender_name}}

The prop 'candidate' is passed from its parent component

Answer №1

A helpful technique in this scenario would be to utilize a computed property. It is important to keep in mind that you may need to implement some chaining if there is a possibility that either this property or any of its parent properties are undefined.

computed: {
  gender() {
    return this.candidate.gender.gender.gender_name;
  }//chaining:
  gender_safe() {
    return this.candidate && this.candidate.gender && this.candidate.gender.gender && this.candidate.gender.gender.gender_name;
  }
}
