import { createRouter, createWebHistory } from 'vue-router';
import Home from './views/Home.vue';
import Product from './views/Product.vue';
import Login from './views/Login.vue';
import Register from './views/Register.vue';
import Cart from './components/Cart.vue';

const routes = [
  { path: '/', name: 'Home', component: Home },
  { path: '/product/:id', name: 'Product', component: Product },
  { path: '/login', name: 'Login', component: Login },
  { path: '/register', name: 'Register', component: Register },
  { path: '/cart', name: 'Cart', component: Cart, meta: { requiresAuth: true } },
];

const router = createRouter({
  history: createWebHistory(),
  routes,
});

router.beforeEach((to, from, next) => {
  const requiresAuth = to.matched.some(record => record.meta.requiresAuth);
  const isAuthenticated = !!localStorage.getItem('auth_token'); // Assuming you're storing the auth token in localStorage

  if (requiresAuth && !isAuthenticated) {
    next('/login');
  } else {
    next();
  }
});

export default router;

This ensures that certain routes, like the cart page, are only accessible to authenticated users.
