javascript - How to access external json file objects in vue.js app

Question

How to access JSON objects in the vue.js app I am new in this

import json from './json/data.json'

the JSON file is loaded and now I have to access the objects within it

Answer 1

Just assign the import to a data property

<script>
      import json from './json/data.json'
      export default{
          data(){
              return{
                  myJson: json
              }
          }
      }
</script>

then loop through the myJson property in your template using v-for

<template>
    <div>
        <div v-for="data in myJson">{{data}}</div>
    </div>
</template>

NOTE

If the object you want to import is static i.e does not change then assigning it to a data property would make no sense as it does not need to be reactive.

Vue converts all the properties in the data option to getters/setters for the properties to be reactive. So it would be unnecessary and overhead for vue to setup getters/setters for data which is not going to change. See Reactivity in depth.

So you can create a custom option as follows:

<script>
          import MY_JSON from './json/data.json'
          export default{
              //custom option named myJson
                 myJson: MY_JSON
          }
    </script>

then loop through the custom option in your template using $options:

<template>
        <div>
            <div v-for="data in $options.myJson">{{data}}</div>
        </div>
    </template>
