Reloading a Datatable in VueJS: Step-by-Step Guide

When developing applications with VueJS, it’s common to manage data displayed on components like tables. One common challenge developers face is reloading a datatable after making changes to the underlying data, such as deleting a row. This post walks you through the solution to reload a Vuetify datatable when a row is deleted, ensuring your app reflects the most current data available.

Understanding the Problem

In the scenario described, a Vue component uses Vuetify's v-data-table to manage a list of balances fetched from a backend service. Each row has a "Delete" button that, when clicked, sends a request to delete that particular entry from the database. However, the table does not update to reflect the deletion immediately, as invoking the fetch function again seems ineffective. Let's explore the necessary adjustment to make this process work seamlessly.

The Solution: Using Async/Await

The fundamental issue here is that the fetch operation is being called immediately after the delete request is sent, without waiting for the delete operation to complete. To effectively manage this, we can use async and await to ensure that we only fetch the new data after the delete action has resolved. Here’s how to modify the sendRequest() method.

Step 1: Update the sendRequest() Method

Instead of the original sendRequest() method, you should declare it as an async function and use the await keyword before the post request to ensure it completes before fetching new data. Here’s the updated code:

Step 2: Implementation Explained

Declare Method as Async: By declaring the sendRequest() function as async, you allow the use of the await keyword inside it.

Awaiting the Post Request: When you send the delete request, use await to pause the execution of the function until the request is complete. This ensures that the data has been successfully deleted from the server before you attempt to refresh the datatable.

Conclusion

Reloading a datatable in VueJS after modifying the data (like deleting a row) is a common challenge faced by developers. By utilizing async functions and awaiting the resolution of your delete requests, you can effectively reload the data in your Vuetify datatable. This approach ensures a smoother and more reliable user experience as your application reflects real-time changes.

By integrating the solution discussed, your VueJS application will now handle data updates more effectively, providing users with updated information promptly after actions such as deletions.
