Basically you have to generate a global cancel token

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

and use it in all your requests by passing it in the config parameter

GET request:

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

POST request:

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

Then, within a vue-router beforeEach navigation guard you can cancel all requests using:

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

Here's the official axios guide for cancellation: https://github.com/axios/axios#cancellation

Answer from @fabruex is correct. I just wanted to add here that if you have lot of api calls then you have to pass cancellation token in each api call config. In order to reduce that code, you can create axios instance and add request interceptor which will add that common cancellation token and then you can assign a new value to token when cancellation is done or your route has changed.

// Some global common cancel token source

let cancelSource = axios.CancelToken.source();

// Request interceptor

export const requestInterceptor = config => {
  config.cancelToken = cancelSource.token;
  return config;
};

// Add request interceptor like this
const request = axios.create({ baseURL: SOME_URL });
request.interceptors.request.use(requestInterceptor);


// Now you can use this axios instance like this

await request.get('/users');

// and

await request.post('/users', data);

// When you will cancel
cancelSource.cancel('Your cancellation message');

// And all the api calls initiated by axios instance which has request interceptor will be cancelled.
