How to Asynchronously Fetch Data from an API in Vue.js to Create a Table

Creating web applications often involves displaying data fetched from an API. If you're using Vue.js, leveraging its capabilities to manage data and display it in a structured way can enhance your application's functionality greatly. In this article, we'll guide you through the process of asynchronously fetching data from an API and displaying it in a table using Vue.js.

The Problem at Hand

In many real-world applications, developers need to fetch user data from an external source and display it in a table format. In this case, the goal is to retrieve a list of users from an API and present their information—such as ID, name, and phone number—in a user-friendly table. However, if you're new to Vue.js, you may run into issues where your code does not work as expected.

A Sample HTML Structure

Here's a simplified version of the HTML code you might be working with:

The Solution

To effectively fetch and display data from the API, we need to correctly structure our Vue instance and methods. Here’s the improved solution step-by-step.

1. Setting Up Your Vue Instance

Firstly, we need to create a Vue instance with the necessary data properties and methods.

2. Key Changes Explained

Data Structure: The rows data property is initialized as an empty array, which allows for dynamic population after data fetching.

fetchData Method: This method now properly fetches data from the API and assigns the entire response array to this.rows. Remember:

You cannot access individual fields using dot notation like finalRes.id as the response is an array of objects. Instead, you should directly assign the whole response.

3. Complete HTML Integration

Make sure to include the Vue.js script in your HTML file:

This script tag must be included before your Vue.js instance code to ensure that Vue is loaded and available for use.

4. Final Code Example

Putting it all together, your HTML and JavaScript should look like this:

Conclusion

Fetching data asynchronously and displaying it using Vue.js is a powerful approach to creating interactive web applications. By following these steps, you can seamlessly integrate API data into your Vue.js applications. Now you can build dynamic UIs that react to real-time data with ease!
