How to Display Axios Response in Vue.js

If you're new to Vue.js, working with APIs and handling responses can be a bit tricky. One common scenario is sending data to a server using Axios and displaying the response received. In this post, we’ll address how to properly manage and display responses from Axios so you can have a dynamic and interactive application.

The Problem

You are using Axios to send a POST request to a server, and when you receive a response, you want to display it using a variable. However, you’re encountering issues when attempting to show the response in your template. Here’s a brief look at the original setup:

Explanation of Changes

Simplified Logic: Instead of using separate commands for setting text.value based on the error response, we’ve combined the logic into a single statement. This makes the code cleaner and easier to read.

Use of Ternary Operator: The ternary operator allows for concise conditional logic. In this case, we check if there’s an error in response.data.error. If there is, we assign the error message to text.value; otherwise, we set it to a confirmation message indicating everything is okay.

Logging the Response: To debug and confirm that your response is being handled correctly, we added a check to log text.value if it's not undefined.

Final HTML Rendering

Your template remains unchanged and will now dynamically reflect the response from your Axios request:
