Axios Intercepters でリフレッシュ トークンを自動化しましょう!

axios.get('https://www.someapi.com/fetch-data').then((data)=> {
// doing something with the Data
},{}).catch((error)=> {
    if(error.response.statusCode === 401){
        // If Token Expired
        RefreshToken()
        window.alert("Session Expired Please Reload the Window!")
    }
})

axios.interceptors.response.use(
  (response) => response,
  async function (error) {
    const originalRequest = error.config;
    if (error.response.status === 401 && !originalRequest._retry) {
      if (isRefreshing) {
        return new Promise((resolve, reject) => {
          failedQueue.push({ resolve, reject });
        })
          .then((token) => {
            originalRequest.headers["Authorization"] = "Bearer " + token;
            return axios(originalRequest);
          })
          .catch((err) => {
            return Promise.reject(err);
