Imagine retrieving a list of products from the state manager in your Vue.js component, where a computed property is then used to process this list for display on the DOM.
<template>
<span>{{ computedProducts }}</span>
</template>
<script>
export default {
created () {
this.$store.dispatch('getProducts')
},
computed: {
products () {
// This operation is asynchronous
return this.$store.state.products
},
computedProducts () {
// Perform processing on the products array
return this.products
}
}
}
</script>
An issue arises when trying to use computedProducts before it has been defined.
A potential workaround involves checking if there are any products available before rendering:
<span v-if="products.length > 0">{{ computedProducts }}</span>
Another option could be returning a Promise from the products state and handling product processing in the created hook. However, this approach may seem like a temporary fix. Are there better alternatives?
