Nuxt 3 how to catch 401 unauthorised globally

Create a util in utils/larafetch

import { useAuthStore } from "~/stores/auth";
const CSRF_COOKIE = "XSRF-TOKEN";
const CSRF_TOKEN = "X-Xsrf-Token";

export async function larafetch(path, options = {}) {
  const { backendURL, frontendURL } = useRuntimeConfig().public;

  //get token
  let token = useCookie(CSRF_COOKIE).value;

  if (
    process.client &&
    ["post", "delete", "put", "patch"].includes(
      options?.method?.toLowerCase() ?? ""
    ) &&
    !token
  ) {
    await initCsrf();
    token = getCookie(CSRF_COOKIE);
  }

  //set headers
  let headers = {
    ...options.headers,
    accept: "application/json",
    [CSRF_TOKEN]: token,
  };
  if (process.server) {
    headers = {
      ...headers,
      ...useRequestHeaders(["cookie"]),
      referer: frontendURL,
    };
  }

  //fetch operation
  const result = await useFetch(path, {
    ...options,
    baseURL: backendURL,
    credentials: "include",
    headers,
  });



//handle error
  const { error, status } = result;
  if (status.value === "success") {
    return result;
  } else {


	//handle 401 here


    switch (error.value.statusCode) {
      case 401:
      case 419:
        const authStore = useAuthStore();
        authStore.user = null;
        navigateTo("/login");
        break;
      case 409:
        navigateTo("/verifyemail");
        break;
      case 500:
        console.log("server error");
        break;
      default:
        return result;
    }
  }
}

async function initCsrf() {
  const { backendURL } = useRuntimeConfig().public;
  await useFetch("/sanctum/csrf-cookie", {
    baseURL: backendURL,
    credentials: "include",
    server: false,
  });
}
function getCookie(name) {
  const match = document.cookie.match(
    new RegExp("(^|;\s*)(" + name + ")=([^;]*)")
  );
  return match ? decodeURIComponent(match[3]) : null;
}

use case example

async function login(form) {
    conts { error, status } = await larafetch("/login", { method: "post", body: form });
   //todo
  }

use case example 2

const { data } = await larafetch(`/dashboard/posts`);

Also when using default useFetch include "credentials:include" option, i.e.,

const { data } = await useFetch(`/posts`, {credentials: "include", baseURL: backendURL,});
