How do I use cancel tokens in Axios?

You can use cancel tokens in Axios to cancel ongoing requests. First, create a cancel token using axios.CancelToken.source(). Then, pass the token to your request.

Can you show me a code example?

Sure! Here's a simple example:

const axios = require('axios');
const CancelToken = axios.CancelToken;

const source = CancelToken.source();

axios.get('/some/endpoint', { cancelToken: source.token })
  .then(response => {
    console.log(response.data);
  })
  .catch(thrown => {
    if (axios.isCancel(thrown)) {
      console.log('Request canceled', thrown.message);
    } else {
      // handle error
    }
  });

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

What happens if I don't use a cancel token?

If you don't use a cancel token, the request will continue to execute even if you no longer need the response, which can lead to unnecessary resource usage.
