You can use axios HTTP client. It already has implemented Interceptors feature. You can intercept requests or responses before they are handled by then or catch.

https://github.com/mzabriskie/axios#interceptors

// Add a request interceptor
axios.interceptors.request.use(function (config) {
    // Do something before request is sent
    return config;
  }, function (error) {
    // Do something with request error
    return Promise.reject(error);
  });

// Add a response interceptor
axios.interceptors.response.use(function (response) {
    // Do something with response data
    return response;
  }, function (error) {
    // Do something with response error
    return Promise.reject(error);
  });
