// router/index.js
import { createRouter, createWebHistory } from 'vue-router';
import HomeView from '../views/HomeView.vue';
import AboutView from '../views/AboutView.vue';

const routes = [
  {
    path: '/',
    name: 'home',
    component: HomeView
  },
  {
    path: '/about',
    name: 'about',
    component: AboutView
  },
  {
    path: '/user/:id',
    name: 'user',
    component: () => import('../views/UserView.vue'),
    props: true // Pass route params as props to component
  }

const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),

export default router;

// main.js
import { createApp } from 'vue';
import App from './App.vue';
import router from './router';

const app = createApp(App);
app.use(router);
app.mount('#app');

// components/NavigationMenu.vue (Example of programmatic navigation)
<template>
  <nav>
    <router-link to="/">Home</router-link> |
    <router-link to="/about">About</router-link> |
    <button @click="goToUser(1)">Go to User 1</button>
  </nav>
</template>

const router = useRouter();

const goToUser = (id) => {

  // Alternatively: router.push(`/user/${id}`);
};
</script>

// App.vue
<template>
  <NavigationMenu />
  <router-view />
