Vue Load Data To Variable from API

If you are looking to learn how to load data to a variable from an API using Vue.js, then you have come to the right place. In this article, we will explore the steps to achieve this with the help of Vue.js and a simple API.

Step 1: Set up your Vue.js project

First, make sure you have Vue.js installed in your project. If not, you can include it via CDN or npm. To include it via CDN, add the following script tag to your HTML file:

    
      <script src="https://cdn.jsdelivr.net/npm/vue@2.6.14/dist/vue.js"></script>
    
  

If you are using npm, you can install Vue.js by running the following command in your terminal:

    
      npm install vue
    
  

Step 2: Create a Vue instance and a data variable

Next, create a new Vue instance in your JavaScript file and define a data variable to store the API response. Here’s an example of how to do this:

    
      var app = new Vue({
        el: '#app',
        data: {
          apiData: null
        }
      });
    
  

Step 3: Fetch data from the API

Now, you can use the fetch or axios library to make a GET request to the API and store the response in the apiData variable. Here’s an example using the fetch method:

    
      fetch('https://api.example.com/data')
        .then(response => response.json())
        .then(data => {
          app.apiData = data;
        });
    
  

Step 4: Display the data in your HTML

Finally, you can use Vue.js template syntax to display the data from the API in your HTML file. Here’s an example of how to do this:

    
      <div id="app">
        <ul v-if="apiData">
          <li v-for="item in apiData">{{ item.name }}</li>
        </ul>
        <p v-else>Loading...</p>
      </div>
