Cancellation

AbortController

Starting from v0.22.0 Axios supports AbortController (opens new window) to cancel requests in fetch API way:

const controller = new AbortController();

axios.get('/foo/bar', {
   signal: controller.signal
}).then(function(response) {
   //...
});
// cancel the request
controller.abort()

CancelToken deprecated

You can also cancel a request using a CancelToken.

The axios cancel token API is based on the withdrawn cancelable promises proposal (opens new window).

This API is deprecated since v0.22.0 and shouldn't be used in new projects

You can create a cancel token using the CancelToken.source factory as shown below:

const CancelToken = axios.CancelToken;
const source = CancelToken.source();

axios.get('/user/12345', {
  cancelToken: source.token
}).catch(function (thrown) {
  if (axios.isCancel(thrown)) {
    console.log('Request canceled', thrown.message);
  } else {
    // handle error
  }
});

axios.post('/user/12345', {
  name: 'new name'
}, {
  cancelToken: source.token
})

// cancel the request (the message parameter is optional)
source.cancel('Operation canceled by the user.');

You can also create a cancel token by passing an executor function to the CancelToken constructor:

const CancelToken = axios.CancelToken;
let cancel;

axios.get('/user/12345', {
  cancelToken: new CancelToken(function executor(c) {
    // An executor function receives a cancel function as a parameter
    cancel = c;
  })
});

// cancel the request
cancel();

Note: you can cancel several requests with the same cancel token / signal.

During the transition period, you can use both cancellation APIs, even for the same request:

const controller = new AbortController();

const CancelToken = axios.CancelToken;
const source = CancelToken.source();

axios.get('/user/12345', {
  cancelToken: source.token,
  signal: controller.signal
}).catch(function (thrown) {
  if (axios.isCancel(thrown)) {
    console.log('Request canceled', thrown.message);
  } else {
    // handle error
  }
});

axios.post('/user/12345', {
  name: 'new name'
}, {
  cancelToken: source.token
})

// cancel the request (the message parameter is optional)
source.cancel('Operation canceled by the user.');
// OR
controller.abort(); // the message parameter is not supported
