[Vue warn]: Failed to resolve component: router-view

Question

I'm a newbie to Vue.js and first time dealing with vue-router. Just created a few files and for some reason I don't get to see the template. Compiled successfully but in the browser I get the following error: Failed to resolve component: router-view

main.js

import { createApp } from 'vue';
import VueRouter from 'vue-router';
import { store } from './store';
import App from './App.vue';
import AuthHandler from './components/AuthHandler';

const router = new VueRouter({
    mode: 'history',
    routes: [
        { path: '/oauth2/callback', component: AuthHandler }
    ]
});

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

App.vue

<template>
  <div>
    <AppHeader></AppHeader>
    <router-view></router-view>
  </div>
</template>

<script>
import AppHeader from "./components/AppHeader";
export default {
  name: "App",
  components: {
    AppHeader
  }
};
</script>

components/AuthHandler.vue

<template>
  <div>
    ... Please wait
  </div>
</template>

<script>
export default {
  name: "AuthHandler"
};
</script>

Here is the package.json

I resolved the problem in the following way. I believe the issue relay on the vue/vue-router versions. I hope this is the correct way :-)

main.js

import { createApp } from 'vue';
import App from './App.vue';
// import VueRouter from './vue-router';
import { createWebHistory, createRouter } from "vue-router";
import { store } from './store';
import AuthHandler from './components/AuthHandler';

const router = createRouter({
    history: createWebHistory(),
    routes: [
        { path: '/about', component: AuthHandler }
    ]
});

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

I was an idiot, I wanted to use 'vue add vue-router'. Of course it didn't work.

Vue add router

is the command.

npm install vue-router@4

only installs the package, won't add it to the app. If all is well, main.js should look like this:

import App from "./App.vue";
import router from "./router";

createApp(App).use(router).mount("#app");

Unfortunately they forgot to add it to the documentation...
