axios is not defined

This error typically occurs when the Axios library is not properly imported or initialized in the code. To resolve the issue, make sure that the Axios library is installed and imported into the project.

You can install Axios via npm with the following command:

npm install axios

Then, you can import Axios into your code like this:

import axios from 'axios';

Make sure that the import statement is at the top of your file, and that you are using the correct path to the Axios library.

If you are using Axios in a script tag in an HTML file, make sure that you have included the Axios library via a CDN or by downloading and referencing the library in your HTML file.

Once you have properly imported Axios, you should be able to use its methods and functions without encountering the "axios is not defined" error.
