Blocking access to specific pages using Axios interceptors is a powerful feature to enhance security and

I am implementing a feature to prevent unauthorized users from accessing personal account pages. Currently, Axios interceptors monitor error responses with a status of 401, indicating that a user is not authorized to view certain pages. If this status is detected, the user is automatically redirected to the login page using the following code:

axiosInstance.interceptors.response.use(null, (error) => {
  if (error.response.status === 401) {
    if (router.history.current.fullPath.includes('profile')) {
      router.replace({
        path: '/login',
      });
    }
    this.$cookie.delete('token');
  }
  if (error.response.status === 404) {
    router.push({ name: 'error' });
  }
  if (error.response.status === 500) {
    router.push({ name: 'server_error' });
  }
  return Promise.reject(error);
});

While this functionality works as intended, I have noticed some odd behavior in the interface. When an unauthorized user attempts to access a restricted page, they briefly see the page before being redirected to the login page. Is there a way to skip this brief visibility and go straight to the login page without revealing the blocked page?

In my opinion, a great solution would be to implement navigation guards. You can learn more about them here.

Here's an example:

const router = new VueRouter({
  routes: [
    {
      path: '/bar',
      component: Bar,
      beforeEnter: (to, from, next) => {
        if (!isLoggedIn()) {
          next({
            path: '/login'
          })
        } else {
          next()
        }
      }
    }
  ]
})
