Utilizing Vue to Refine JSON Data

Exploring the use of axios in conjunction with Vue has been my recent focus, but I find myself pondering a more general JSON inquiry.

After successfully retrieving data from my local products.json file using axios, I'm implementing filter to generate a new array containing only products that share a similar department property, and subsequently displaying them through iteration.

I wonder if this methodology is optimal, or if it's possible to somehow apply the filtering directly within the initial axios call. I've read about passing parameters to trigger specific database queries and return only the necessary JSON data initially.

data(){
    return {
        products: []
    }
},
components: {
    Product
},
computed: {
    foodProducts(){
        return this.products.filter(x => x.department == 'Food')
    }
},
mounted() {
    axios
    .get('./json/products.json')
    .then(response => (this.products = response.data.products))
}

Your input on this matter would be greatly appreciated as I continue delving into the underlying concepts.

Answer №1

There are various ways to make it work depending on your specific scenario or needs.

Your approach is effective. Another option is to directly filter the result from the API call as long as the backend provides a complete result.

data() {
 return {
  filteredItems: []
 }
}

mounted() {
 axios.get(API_URL)
  .then(response => {
   const items = response.data

   this.filteredItems = items.filter(item => item.category.includes('fruits'))
  })
}

Answer №2

When accessing the product list from a Back-end server, consider utilizing query parameters such as:

xxx/products?department=XXX

This allows the backend server to handle the filtering process for you.

In this particular scenario, it appears that you are directly reading data from a local JSON file. As a result, the entire JSON dataset is returned, requiring you to implement your own filtering mechanisms.
