Is there a Handlbars equivalent to Jades extend - express

I'm contemplating moving the tempating language of my express app from Jade to Handlbars, and I'm wondering if there is an equivalent to the Jade extend directive in handlebars.

As i can see, in the repository of handlebars tells you that exist a dependencie for handlebars that can enable you to extends blocks. You can found more information here and here.
layout.hbs
<!doctype html>
<html lang="en-us">
<head>
{{#block "head"}}
<title>{{title}}</title>
<link rel="stylesheet" href="assets/css/screen.css" />
{{/block}}
</head>
<body>
<div class="site">
<div class="site-hd" role="banner">
{{#block "header"}}
<h1>{{title}}</h1>
{{/block}}
</div>
<div class="site-bd" role="main">
{{#block "body"}}
<h2>Hello World</h2>
{{/block}}
</div>
<div class="site-ft" role="contentinfo">
{{#block "footer"}}
<small>© 2013</small>
{{/block}}
</div>
</div>
{{#block "foot"}}
<script src="assets/js/controllers/home.js"></script>
{{/block}}
</body>
</html>
Here we define a basic layout where you can extend others html from this one.
page.html
{{#extend "layout"}}
{{#content "head" mode="append"}}
<link rel="stylesheet" href="assets/css/home.css" />
{{/content}}
{{#content "body"}}
<h2>Welcome Home</h2>
<ul>
{{#items}}
<li>{{.}}</li>
{{/items}}
</ul>
{{/content}}
{{#content "foot" mode="prepend"}}
<script src="assets/js/analytics.js"></script>
{{/content}}
{{/extend}}
In this file you set all the data you want to extend from layout.
The .js file
var handlebars = require('handlebars');
var layouts = require('handlebars-layouts');
// Register helpers
handlebars.registerHelper(layouts(handlebars));
// Register partials
handlebars.registerPartial('layout', fs.readFileSync('layout.hbs', 'utf8'));
// Compile template
var template = handlebars.compile(fs.readFileSync('page.html', 'utf8'));
// Render template
var output = template({
title: 'Layout Test',
items: [
'apple',
'orange',
'banana'
]
});
1. Require handlebars and handlebars-layout
2. Register the helper in the handlebar as a layout.
3. Register partials set the file layout.hbs as a "module" called 'layout', then in the page.html you set the extension from 'layout'
4. Compile in template the extension page.html.
5. Render template passing data from js to the file.

For those looking for a webpack solution. I leave a snippet of code with my configuration:
webpack.config.js
...
const fs = require("fs")
const HandlebarsPlugin = require("handlebars-webpack-plugin")
const HandlebarsLayouts = require('handlebars-layouts');
module.exports = {
...,
plugins: [
...,
new HandlebarsPlugin({
...,
onBeforeSetup: function(Handlebars){
Handlebars.registerHelper(HandlebarsLayouts(Handlebars));
Handlebars.registerPartial('default', fs.readFileSync('path/to/layout.hbs', 'utf8'));
}
})
]
}

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>

Fullcalendar with Vue without CLI

I have a small Vue project that isn't in a build environment that is just a bunch of JS files and uses Vue from the CDN
I would like to use FullCalendar in my Vue project and ideally use the official FullCalendar Vue component, but this only seems to be available for projects using the CLI build environment.
Is there a Vue component available for non-build projects that I could use that still implements the normal <FullCalendar /> tag?
About CDN see
new Vue({
el: '#app',
mounted() {
var calendarEl = document.getElementById('calendar');
var calendar = new FullCalendar.Calendar(calendarEl, {
initialView: 'dayGridMonth'
});
calendar.render();
}
})

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">
<title>#ViewData["Title"] - ARMS 2.0</title>

</body>
</html>

</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>

VueJS: Call function from bootstrap/jQuery script includes in template/layout from a component

i am very new to VueJS and want to build an Admin Dashboard for an existing bootstrap template (SB Admin Pro). I know there is a BootstrapVUE but we want to use the specified template that we purchased before. So this is not an option for me/us.
My Goal:
In our vue component we make an axios call to our backend to retrieve and show some data. If the call fails we want to call in the catch block a bootstrap function for toast to show some notification to the user (like: Error while fetching data from backend...). We included the bootstrap and jquery libraries from the template in the default index.html.
The Problem:
I don't know how to call the toasts (or other) functions from the vue component. In the template the call looks like this:
$("#toastBasic").toast("show");
Our index.html looks
<!DOCTYPE html>
<html lang="en">

<div class="container-fluid mt-n10">

</div>
<div class="row">
<Card cHeader="Eine Karte" class="col-md-12"> {{ contacts }}</Card>
</div>
</div>
</main>
</template>
<script>
import ContentHeader from '../../components/ContentHeader'
import Card from '../../components/Card'
import axios from 'axios';
export default {
name: "Contact",
components: {
ContentHeader,
Card,
},
data() {
return {
contacts: null,
error: null
}
},
mounted() {
const url = 'http://localhost:3000/v1/';
axios.get(url + 'contsact')
.then(response => {
this.contacts = response.data
console.log(response)}
)
.catch(error => {
console.log(error.response)
$("#toastBasic").toast("show");
});
}
}
</script>
In vue.config.js, specify jquery as external (this tells webpack where to provide jquery from when it's imported in any component):
configureWebpack: {
externals: {
jquery: 'window.jQuery'
}
}
Place all the <script>s you want loaded by the time Vue inits in your public/index.html page, in the <head> tag and remove their defer attribute. This includes any jquery plugin (or anything requiring/extending jquery) you might want to use in your Vue app (in your case, bootstrap.min.js).
The above will make it work when developing (in serve). You'll need to do the same for prod: Load jquery and any dependency before initing the Vue app.
Now you can safely use
import * as $ from 'jquery'
in any component.
Webpack will place in $ whatever window.jQuery is at the moment the component inits.
The above approach makes sure all required scripts are loaded before Vue inits (which is a bit extreme, but it makes sure there's no way you can call the jquery method before its dependencies are loaded).
If you don't want to wait for jquery and bootstrap.min.js to load before you init your Vue app, a trick you could use is to assign jquery from window object just before you need it:
yourAlertMethod() {
const $ = window.jQuery;
$.toast()...
}
Obviously, you no longer have to move all the scripts in <head> and to remove their defer. This second method doesn't guarantee they would have already loaded before your method is first used. But your app inits faster.
Here's a basic example.
I used the second method, codesandbox.io doesn't have support for #vue/cli v3 hence vue.config.js doesn't work as in a Vue project created with vue create. Therefore, I had to use the second method.
The full list of dependecies you need to load before you call the $(el).toast() method:
bootstrap.min.css
jquery.js
popper.js
bootstrap.min.js
(see them in public/index.html). You can copy/paste them from Bootstrap.
You can get ref of the element and pass it to jQuery
<div ref="toast" class="toast" id="toastBasic" role="alert" aria-live="assertive" aria-atomic="true" data-delay="5000">
import $ from 'jQuery';
$(this.$refs.toast).toast("show");
I don't recommend that though.

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.
