how to cancel an axios post request in javascript

To cancel an Axios post request in JavaScript, you need to create a cancel token and pass it along with the request using the cancelToken config parameter. You can then call the cancel() method of the cancel token to cancel the request.

Here's an example code snippet:

index.tsx
import axios from 'axios';

const source = axios.CancelToken.source();

axios.post('/api/post', { data }, { cancelToken: source.token })
  .then(response => console.log(response))
  .catch(error => {
    if (axios.isCancel(error)) {
      console.log('Request canceled', error.message);
    }
  });

// To cancel the request
source.cancel('Operation canceled by the user.');

In the above code, the axios.CancelToken.source() method creates a new cancel token with a cancel function attached. This token is passed as a cancelToken parameter to the axios.post() method. source.token is the cancel token that contains the cancel() method.

To cancel the request, you simply call the cancel() method of the source object with an optional cancel error message. When the axios.isCancel() function is called within the error handling block, it checks if the error is related to the cancellation of the request.
