[Vuejs]-How to configure a vuejs app with an external file

Step 1: Create the configuration file
Create a new JSON file (e.g., config.json) that contains the configuration settings you want to use in your Vue.js app:

     {
      "apiBaseUrl": "https://api.example.com",
      "apiKey": "your_api_key_here",
      "enableFeatureX": true,
      "maxItemsPerPage": 10
     }

Step 2: Import the configuration file in your Vue app

In your Vue app’s entry point (e.g., main.js), import the configuration file using an HTTP request or a build tool like Webpack.

Example using Axios (ensure you have Axios installed):

import Vue from 'vue';
import App from './App.vue';
import axios from 'axios';

axios.get('/path/to/config.json')
  .then(response => {
    Vue.prototype.$config = response.data;
    new Vue({
      render: h => h(App),
    }).$mount('#app');
  })
  .catch(error => {
    console.error('Error loading config:', error);
  });

Step 3: Use the configuration settings in your Vue components

Now that you’ve loaded the configuration settings into Vue’s prototype, you can access them in your Vue components using this.$config.

For example, in any of your Vue components:

<template>
  <div>
    <p>API Base URL: {{ $config.apiBaseUrl }}</p>
    <p>API Key: {{ $config.apiKey }}</p>
    <p v-if="$config.enableFeatureX">Feature X is enabled.</p>
    <p>Max Items Per Page: {{ $config.maxItemsPerPage }}</p>
  </div>
</template>

<script>
export default {
  mounted() {
    console.log('API Base URL:', this.$config.apiBaseUrl);
    console.log('API Key:', this.$config.apiKey);
  },
};
</script>
