import Vue from 'vue';
import VueRouter from 'vue-router';
import axios from 'axios';
import VueAxios from 'vue-axios';
Vue.use(VueAxios,axios,VueRouter);
axios.defaults.headers.common['X-CSRF-TOKEN'] = Laravel.csrfToken;
const Foo = { template: '<div>foo</div>' }

Im really having a hard time because when i compile it i receive an error that router-link is not registered but when i put my script tags on the upper part
app is not found
how can i make this thing work?

IIUC: an html renders at server-side, with a script injected to it, the script contains your compiled vue component, and will mount it to a node in the dom. Which means, the php file containing router-link will only be passed through php parser, who have no idea what router-link is. Only front end compilers know how to handle router-link, so you need to put it in your vue component's template (to make it go through front end compiler who understands it). Also, when you're mounting to #app, contents inside it will be overwritten by vue, so avoid putting useful things inside, but reorganize your html or put them in your vue component instead.

Vuetify instance with cdn not work on vuejs3

I have application on aspnet mvc and import vuejs v3 cdn and i like use vuetify but i dont know how do it.
its my code example
<!DOCTYPE html>
<html lang="en">
<head>
<title>#ViewData["Title"] - MVCAndVue</title>
<link href="https://cdn.jsdelivr.net/npm/vuetify#2.x/dist/vuetify.min.css" rel="stylesheet">
<script src="https://unpkg.com/vue#next"></script>
</head>
<body>
<div class="container">
<main role="main" class="pb-3">
#RenderBody()
</main>
</div>
#await RenderSectionAsync("Scripts", required: false)
</body>
</html>
<script>
const {
ref,
reactive,
} = Vue;
//Define Vue app
const App = {
data() {
return {
};
},
methods: {
},
setup(props, context) {
}
};
// Create new Vue app
const app = Vue.createApp(App);
app.mount("#app");
</script>
You are facing this issue because you included Vuetify 2.x which is not compatible with Vue 3. So, use Vuetify 3 instead.
Now, the right way to use Vuetify via CDNs, you need to follow these steps-
Import Vuetify CSS in your head tag-
<link
href="https://cdn.jsdelivr.net/npm/vuetify#3.0.5/dist/vuetify.min.css"
rel="stylesheet"
/>
If you want to use material design icons, then import this CSS link in your head tag too-
<link
href="https://cdn.jsdelivr.net/npm/#mdi/font#4.x/css/materialdesignicons.min.css"
rel="stylesheet"
/>
Import the Vuetify script in your body tag-
<script src="https://cdn.jsdelivr.net/npm/vuetify#3.0.5/dist/vuetify.min.js"></script>
If you are planning to use Vue3 also via CDN, then import the Vue script in your body tag-
<script src="https://unpkg.com/vue#3/dist/vue.global.js"></script>
Here is a complete working HTML file with all necessary imported CDNs for Vue3 and Vuetify3-
<!DOCTYPE html>
<html>
<head>
<link
href="https://cdn.jsdelivr.net/npm/#mdi/font#4.x/css/materialdesignicons.min.css"
rel="stylesheet"
/>
<link
href="https://cdn.jsdelivr.net/npm/vuetify#3.0.5/dist/vuetify.min.css"
rel="stylesheet"
/>
</head>
<body>
<div id="app"></div>
<script src="https://unpkg.com/vue#3/dist/vue.global.js"></script>
<script src="https://cdn.jsdelivr.net/npm/vuetify#3.0.5/dist/vuetify.min.js"></script>
<script type="text/x-template" id="app-template">
<v-app>
<v-card
class="mx-auto"
width="400"
append-icon="mdi-human-greeting"
>
<template v-slot:title>
Title
</template>
<v-card-text>
Description
</v-card-text>
</v-card>
</v-app>
</script>
<script>
const { createApp } = Vue;
const { createVuetify } = Vuetify;
const vuetify = createVuetify();
const app = createApp({
template: "#app-template",
})
.use(vuetify)
.mount("#app");
</script>
</body>
</html>

Integrating VueJS into ASP.NET Core without nodejs, webpack, or npm

Due to security reasons we cannot install nodejs and any package managers. THerefore, I am trying to build my SPA with cdn support only. However, I am struggling to get it to work as I keep getting the failed to mount template error when running my code. I am using ASP.NET core 3.1 and i am able to get to the page to load up my partial views showing the side navigation and top navigation items. The page loads up and the router seems to work in changing the url in browser but the view components for the actual page templates do not show up on the screen. For instance dashboard view should show up but does not and therefore i believe this is where the issue is but I cannot see any issues with my code.
My code is as follows:
_vueapp:
<!DOCTYPE html>
<html lang="en">
<head>
#RenderSection("Styles", required: false)
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

</div>
#section Scripts
{
<partial name="components/side-navigation" />
<partial name="components/top-navigation" />
<partial name="views/dashboard" />
<partial name="views/reviews" />
<script>
//setup routing using SPA VUE interface
Vue.use(VueRouter);
const routes = [
{ path: '/', component: dashboard },
{ path: '/reviews', component: reviews }
]
const router = new VueRouter({
routes // short for `routes: routes`
})
var app = new Vue({
el: '#app',
router
}).$mount('#app')
</script>
}
side-navigation:
<style>
</style>
<template id="side-navigation">
<div>
<router-link to="/">Home</router-link>
<router-link to="/reviews">Reviews</router-link>
</div>
</template>
<script>
Vue.component('side-navigation', {
template: '#side-navigation'
})
</script>
one of my views which is dashboard:
<style>
</style>
<template id="dashboard">
<div>
<h1>dashboard</h1>
</div>
</template>
<script>
Vue.component('dashboard', {
template: '#dashboard'
})
</script>
You need to assign the components (dashboard and reviews) to a constant, otherwise the router can not recognize them.
dashboard:
<style>
</style>
<template id="dashboard">
<div>
<h1>dashboard</h1>
</div>
</template>
<script>
const dashboard = Vue.component('dashboard', {
template: '#dashboard'
})
</script>
reviews:
<style>
</style>
<template id="reviews">
<div>
<h1>reviews</h1>
</div>
</template>
<script>
const reviews = Vue.component('reviews', {
template: '#reviews'
})
</script>

I am a complete beginner in Vue js and Vue Router, 404 page not found error

I cant seem to get this simple vue router work, its giving this in console GET http://127.0.0.1:8000/my-new-router 404 (Not Found), i am using it with laravel
app.js:
require('./bootstrap');
window.Vue = require('vue');
import router from './router'
Vue.component('navbar', require('./components/navbar.vue').default);
const app = new Vue({
el: '#app',
router
});
router.js:
import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
import firstPage from './components/pages/MyFirstPage'
const routes= [
{
path: '/my-new-router',
component: firstPage
}
]
export default new Router({
model:'history',
routes
})
navbar.vue:
<template>
<div>
<h1>This is a test</h1>
<router-view></router-view>
</div>
</template>
MyFirstPage.vue:
<template>
<div>
</div>
</template>
welcome.blade.php:
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

</head>
<body>
<div id="app">
<navbar></navbar>
</div>
</body>
<script src="{{ asset('js/app.js') }}"></script>
</html>
routes/web.php
<?php
use Illuminate\Support\Facades\Route;
Route::get('/', function () {
return view('welcome');
});
Change the content of web.php to:
<?php
use Illuminate\Support\Facades\Route;
Route::get('{any}', function () {
return view('welcome');
})->where('any', '.*');
This way any route will be forwarded to vue-router.

Vue is not mounting and getting no error messages

I have created a project using vue-cli#4 and its working fine but I have done some changes in main.js and it is not working anymore.
//main.js
import Vue from "vue";
import App from './App.vue'
//Vue.config.productionTip = false;
new Vue({
el: "#root-app",
//commented components property when using render and mount
components: {
App
},
data: {
name: "amandeep Singh"
}
// render: h => h(App),
}); //.$mount('#app')
App.vue file
<template>
<div>
testingggg
<img alt="Vue logo" src="./assets/logo.png">
</div>
</template>
<script>
export default {
name: 'app',
}
</script>
Index.html file
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<link rel="icon" href="<%= BASE_URL %>favicon.ico">

</head>
<body>
<div id="root-app">
{{name}}
<app></app>
</div>
<!-- built files will be auto injected -->
</body>
</html>
It's showing nothing even "name" value is not interpolated.
But if I Uncomment
render: h => h(App),
and
.$mount('#app')
everything works fine.
So my question why does not it with these two commented. I have checked many examples and seen projects where they have not to use render function, all they have used is "el" property to mount vue to Html and everything works.
So someone can please what's happening here? What I am doing wrong?
How can I make work without render and mount and why it is necessary?
You are not rendering the component you imported.
First, you imported the App.vue component which is the base holder of your components: import App from './App.vue'. Good!.
Next, You told Vue about the component you have imported so Vue knows about it (register): components: { App },. Good!
Now, what is left for you to do is to render the App.vue component. Do so by adding back the render function:
render: h => h(App),
Or like so:
template: "<App/>",
You should be good to go now.

What is the difference between this two very basic vue app?

I've been learning Vue.js and I tried to have the root instance not erase the html content I put inside. The idea being that I could have a normal html page and Vue "watching" the main wrapper and if it run into a vue component it will be render by vue. I've managed to do that when I import the CDN of vue but not with the vue cli somehow. I don't understand the difference.
I made this codepen loading vue.js by the cdn and it render without problem
<div id="app">
<h1>My Vue.js App</h1>
<p>{{ message }}</p>
</div>
new Vue({
el: '#app',
data: {
message: 'Hello world'
}
});
https://codepen.io/cvallee/pen/dLKVEP
But in codesandbox where it use vue cli nothing is render, the content of the root element flash and then disappear from the dom. No matter what I put into the main div it is erase as soon as the app mount. https://codesandbox.io/s/m5qvm40nkx
I think the issue has to do with the way that the CodeSandbox loads the Vue app and triggers the initial render. If you add an App.vue file and change the main.js file to
import Vue from "vue";
import App from "./App.vue";
// Vue.config.productionTip = false;
new Vue({
el: "#app",
render: h => h(App)
});
and the index.html to
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width,initial-scale=1.0" />
<link rel="icon" href="<%= BASE_URL %>favicon.ico" />
<title>codesandbox</title>
</head>
<body>
<div id="app"></div>
</body>
</html>
it works for me this way. Here is the working version - https://codesandbox.io/s/84ox08k24j
