Passing props from a parent component to a nested child component in Vue 3

Question

Passing props from a parent component to a nested child component in Vue 3

My goal is to achieve the functionality described in the title. Suppose I have the following structure:

parent -> child -> secondChild

Currently, there is a variable called isActive in the parent component. Below is how it can be implemented:

parent.vue

<child :active="isActive" />

child.vue

<template>
<secondChild :active="props.active">
</template>


<script setup>

const props = defineProps(['active'])

</script>

secondChild.vue

<template>
{{isActive}}
</template>


<script setup>

const props = defineProps(['active'])

</script>

While this method works, it may not be optimal when dealing with multiple nested components. Any suggestions on achieving this without relying on pinia or vuex?

Appreciate any guidance.

Answer №1

To implement this functionality, you can utilize the provide/inject feature in Vue:

parent.vue

<script setup>
import {provide} from 'vue';

provide('activeStatus', isActive);
</script>

<template>
<childComponent />
</template>

childComponent.vue

<template>
<grandChildComponent />
</template>

grandChildComponent.vue


<template>
<grandChildComponent />
</template>


<script setup>

import {inject} from 'vue';

const isActive = inject('activeStatus', ref(false));

</script>

If you want to create your own implementation of Vue 3 State Management, you can do so by creating a new file.

// stores/customState.js

import { ref } from 'vue'

export const customState = ref(false)

Once you have defined this custom state, you can import it into any component and utilize it as follows. Keep in mind that using ref ensures reactivity across all components...and other options like reactive or computed are also available:

// component.vue

<script setup>
import { customState} from '/stores/customState'

// customState.value is reactive
</script>

<template>
 <!-- Custom state is reactive -->
 {{ customState }}
</template>

While this method works well, it's worth mentioning that if you anticipate sharing this state among multiple components (10 or more), utilizing a library like Pinia would be the recommended approach.

It appears to me that incorporating React's Context API could be beneficial in order to avoid prop drilling. Consider utilizing the Provide/Inject feature instead. By importing provide from vue and implementing it in your parent component to define the data, then using inject to pass that data down to your child component. The structure of your parent component might resemble this:

<template>
  <Provide>
    <div>
      <ChildComponent />
      <div>
         <AnotherChildComponent />
      </div>
    </div>
  </ProvideUserSettings>
</template>

This way, within each ChildComponent, you can include additional components that require access to that data.
