PrimeFlex margin not working inside Vue3 app - vue.js

I want to apply some margin on PrimeVue elements inside my Vue3 app. Based on the example from the docs
https://www.primefaces.org/primevue/showcase/#/selectbutton
I have a working example with a margin between the icon and the text

components: {
"p-selectbutton": primevue.selectbutton
}
};
createApp(App)
.use(primevue.config.default)
.mount("#app");
</script>
</body>
</html>
But the margin does not work in my project. For reproduction:
vue create foo
# select default Vue3 app
cd foo
# based on https://primefaces.org/primevue/showcase/#/setup
npm install primevue
npm install primeicons
npm install primeflex
I change the main.js file to
import { createApp } from 'vue'
import PrimeVue from "primevue/config";
import "primevue/resources/themes/saga-blue/theme.css";
import "primevue/resources/primevue.min.css";
import "primeicons/primeicons.css";
import "primeflex/primeflex.css";
import SelectButton from "primevue/selectbutton";
import App from './App.vue'
createApp(App)
.use(PrimeVue)
.component("p-select-button", SelectButton)
.mount('#app')
I change the App.vue file to
<template>
<p-select-button v-model="selectedValue" :options="options" dataKey="value">
<template #option>
<i class="pi pi-check-circle" />
<span class="p-ml-4">Some text</span>
</template>
</p-select-button>
</template>
<script>
import { ref } from "vue";
export default {
setup() {
const selectedValue = ref();
const options = ref([
{ value: 'left' },
{ value: 'right' }
]);
return { selectedValue, options }
},
}
</script>
When running the app the result is
Does someone know why the margin works in the first sample but not in my code? What am I missing?

Your CDN demo uses PrimeFlex 2:
<link href="https://unpkg.com/primeflex#2.0.0/primeflex.min.css" rel="stylesheet" />
👆
But your app uses PrimeFlex 3 (i.e., npm install primeflex installs 3.1.0). The latest version has removed the p- prefix from all classnames for readability, so the class name is now ml-4.
Solution 1: Update classname to ml-4
You can use PrimeFlex 3's classname in App.vue:
<!-- BEFORE -->
<span class="p-ml-4">Some text</span>
<!-- AFTER -->
<span class="ml-4">Some text</span>
demo 1
Solution 2: Downgrade to PrimeFlex 2
If you prefer to use the existing version (perhaps to minimize changes in a large app), install PrimeFlex 2 instead:
npm install -S primeflex#2

Use vuejs 3 without router

I created a vuejs3 single page application "WITHOUT" router and routing and also without "url" change ( want to always showing home in address bar)
But need help to do it in a correct way.
I want to
have a main html page on page have links, buttons or so, that at run
time page is filed (how???)
on start page be filled with the first home page
on click of each link or buttons the selected component to be replace in the page
index.html page:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<link rel="icon" type="image/svg+xml" href="/vite.svg" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Vite + Vue</title>
</head>
<body>
<div id="app"></div>
<script type="module" src="/src/main.js"></script>
</body>
</html>
main.js
import { createApp } from 'vue'
import App from './App.vue'
import store from './store'
import './style.css'
const app = createApp(App)
app.use(store)
app.mount('#app')
app.vue file
<template>
<div>
<h1>Hello world</h1>
<button type="button" #click="changeView(0)"> Home 1 </button>
<button type="button" #click="changeView(1)"> Home 2 </button>
<button type="button" #click="changeView(2)"> Home 3 </button>
</div>
<Suspense v-if="isLoggedIn">
<template #default>
<changeViews />
</template>
<template #fallback>
<p>loading...</p>
</template>
</Suspense>
<changeViews v-if="showIt" />
</template>
<script setup>
import { defineAsyncComponent, ref, markRaw } from 'vue'
const menus = [
{
name: "home"
,url: "home"
},
{
name: "about"
,url: "about"
},
{
name: "contact"
,url: "contact"
},
]
let showIt = ref(false)
let changeViews = ref(null)
changeViews.value = markRaw(defineAsyncComponent((loc) =>
import(`./components/${menus[0].url}/index.vue`)
))
function changeView(ja){
showIt.value = false
if(ja===1) {
showIt.value = true
changeViews.value = defineAsyncComponent((loc) =>
import(`./components/${menus[ja].url}/index.vue`)
)
}
}
</script>
Pages (home, about, contact) are very simple:
<template>
<h2> Home </h2>
<div class="card">
<button type="button" #click="count++">count is {{ count }}</button>
<button type="button" #click="count++">count is {{ count }}</button>
<button type="button" #click="count++">count is {{ count }}</button>
</div>
</template>
<script lang="ts" setup>
import { ref } from 'vue'
const count = ref(0)
</script>
It is working, but it seems messy and I have no idea how to do it in a good way.
I have searched but every where they talk about how to use routing, while I want to avoid routing and no url-change
I think you need to use dynamic components. You can dynamically specify which component to render at a single place.
<template>
<component :is="currentPage" />
</template>
<script setup>
import PageA from '#/components/PageA.vue'
import PageB from '#/components/PageB.vue'
import PageC from '#/components/PageC.vue'
const currentPage = ref('PageA')
function changeView(page) {
currentPage.value = page
}
</script>

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">

<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>

Router not working when adding vitejs v2 to Vue v3

An app that has been using webpack for the dev server should now use vite. Everything seems to be working fine (and fast) with the exception of routes. These are simply ignored and only the content of App.vue is rendered.
This is package.json:
{
"name": "mode",
"version": "0.0.0",
"scripts": {
"dev": "vite"
},
"dependencies": {
"vue": "^3.0.5",
"vue-router": "^4.0.4"
},
"devDependencies": {
"#vitejs/plugin-vue": "^1.1.4",
"#vue/compiler-sfc": "^3.0.5",
"vite": "^2.0.2",
"typescript": "~3.9.3"
}
}
The central index.html is:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<link rel="icon" href="/favicon.ico" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Vite App</title>
</head>
<body>
<div id="app"></div>
<script type="module" src="/src/main.ts"></script>
</body>
</html>
In src/main.ts the router is loaded:
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
createApp(App).use(router).mount('#app')
That router is defined in src/router/index.ts:
import { createRouter, createWebHistory } from 'vue-router'
import SomePage from '#/views/SomePage.vue'
const router = createRouter({
history: createWebHistory(),
routes: [{
path: '/some',
name: 'Some',
component: SomePage
}]
})
export default router
The (never shown) src/views/SomePage.vue is:
<template>
<div class="section">
Some content on some page.
</div>
</template>
And this is the (always shown) App.vue:
<template>
<img alt="Vue logo" src="./assets/logo.png" />
<HelloWorld msg="Hello Vue 3 + Vite" />
</template>
<script setup>
import HelloWorld from './components/HelloWorld.vue'
</script>
With this src/components/HelloWorld.vue:
<template>
<h1>{{ msg }}</h1>
<p>
Fancy text.
</p>
</template>
<script setup>
import { defineProps } from 'vue'
defineProps({
msg: String
})
</script>
I would expect http://localhost:3000/some to show the content of SomePage.vue, but only the content of App.vue is rendered, regardless of the route used.
Pointers to what I'm missing here and why the fine route is ignored are appreciated.
You need to add a router-view to go to the page routed.
If you want SomePage to be part of App.vue just do so by
<template>
<img alt="Vue logo" src="./assets/logo.png" />
<router-view />
<HelloWorld msg="Hello Vue 3 + Vite" />
</template>

Why is instead of the Vue component some JS comment added to the DOM?

I am working with BootstrapVue and am trying to dynamically create components after the site is rendered (I want to use asynchronous data for the generation process later) with Vue and add them to the DOM.
(I am simulating the asynchrony in the demo by creating the components with a 1 second delay after the page is loaded).
This is what happens:
Vue is creating the components and then they should be mounted to the DOM. But sadly they don't show up. Instead this comment: <!--function(e,n,r,i){return Pt(t,e,n,r,i,!0)}--> is added to them DOM (at the correct position though) in place of the actual HTML code of the component.
This is the jsfiddle with example code that demonstrates the problem: https://jsfiddle.net/0stdxorj/1
Thank you for your help :).

});
function createCard(props) {
let componentInstance = new cardComponentConstructor(props)
componentInstance.$mount()
document.getElementById("card-container").appendChild(componentInstance.$el)
}
I fixed the problem by going at it in another way. Vue re-renders v-for tags when using a key attribute (:key="card.id"). So I don't try to manually create the components anymore but make use of this feature and modify the cards data instead, which in turn then makes Vue re-render the deleted/modified/added cards:
