I made a simple html file with vue-router.
I use x-template to define component template.
It works well on chrome browser, but I found that IntelliJ IDE show me a red line.
I cannot understand why IDE can't resolve this and why my code works well on the browser even though the symbol can't be resolved.
Does anyone have an idea? (The code is written below)
<!DOCTYPE html>

I'm using markdown vue which is a plugin for vue. It says it's supposed to have superscript and subscript functionality built in, however when I run the code for a subscript I get something that looks like this
y = x b + e
i i i
In order to have this functionality I'm trying to use this plugin but I'm having a hardtime figuring out how it's supposed to be registered globally with the MarkdownItVue plugin. I tried doing this...
import MarkdownItVue from 'markdown-it-vue'
import MarkdownItSub from 'markdown-it-sub'
MarkdownItVue.use(MarkdownItSub)
Vue.use(MarkdownItVue)
But this is working out...
I'm happy to change approaches too if there's a simpler fix for MarkdownItVue

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

</body>
app.js
new Vue ({
el: '#app',
data() {
return {
msg: "$y_i = x_i + \\epsilon_i$"
}
}
})
It seems to be working just fine by default. See the example.
Anyway it seems from the docs that if you need to install additional markdown-it plugins, it needs to be done on component instance
const vm = new Vue({
el: "#app",
data() {
return {
content: "H~2~0 - 29^th^"
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<script src="https://unpkg.com/markdown-it-vue#1.1.6/dist/markdown-it-vue.umd.min.js"></script>
<link rel="stylesheet" href="https://unpkg.com/markdown-it-vue#1.1.6/dist/markdown-it-vue.css">
<div id="app">
<markdown-it-vue :content="content">
</markdown-it-vue>
</div>
The LaTeX rendering requires the stylesheet from markdown-it-vue. Make sure you're including it as a <link>:
<link rel="stylesheet" href="https://unpkg.com/markdown-it-vue#1.1.6/dist/markdown-it-vue.css">
new Vue({
el: "#app",
data() {
return {
content: "$y_i = x_i + \\epsilon_i$"
}
}
})
<script src="https://unpkg.com/vue#2.6.12/dist/vue.min.js"></script>
<script src="https://unpkg.com/markdown-it-vue#1.1.6/dist/markdown-it-vue.umd.min.js"></script>
<link rel="stylesheet" href="https://unpkg.com/markdown-it-vue#1.1.6/dist/markdown-it-vue.css">
<div id="app">
<markdown-it-vue class="md-body" :content="content"></markdown-it-vue>
</div>
Or importing the file from markdown-it-vue/dist/markdown-it-vue.css:

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">

<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 pretty much stuck on it and I'm not even sure if what I was trying is possible.
Here's my project if needed:

I'm not sure how to display it any better as this is the best it gets.. Basically im passing NestedComponent into Component which is getting passed into app.js which is rendering it into the index.html. That's it, for some reason doesn't work.
// "main.js" the Vue file that renders to the index.html
new Vue({
el: '#app',
components: { Component},
template: '<Component/>'
})
import Component from 'Component'
// "Component.vue" that is getting passed into the above "app.js"
<template lang="html">
<div>
<p>{{ title }}</p>
<h1>Hi!</h1>
<NestedComponent/>
</div>
</template>
<script>
import NestedComponent from 'NestedComponent'
export default {
name: 'Component',
components: {
NestedComponent
},
data: {
title: 'Hello'
}
}
</script>
// "NestedComponent.vue" a nested component that is getting passed onto it's parent Component "Component.vue"
<template lang="html">
<div>
<p>{{ im a nested component }}</p>
</div>
</template>
<script>
export default {
name: 'NestedComponent',
components: {
},
data: {
}

There are a few things that I think is causing the problem:
You are using .vue files. They require special loaders via
Webpack or similar tool. They will then be converted into a normal
.js file. In your case, you have a CDN version of Vue so these features will not be available to you.
As people have mentioned before the use of import and export is not supported by the browser natively. This again needs to run through the Webpack or similar tool.
Find similar information in the docs
https://v2.vuejs.org/v2/guide/single-file-components.html
I am trying learn about sub-routes, but the code below dont works.

var firstpage = Vue.component('firstpage',{

var secondpage = Vue.component('secondpage',{

var router = new VueRouter({

{path: '/firstpage', component: firstpage,
children:[

{path: ':sec', name:"second", component: secondpage},

},
]
});
var app = new Vue({
el: "#app",
mode: 'history',
router,
});
</script>

When clicks on "second" or "second test", nothing happens.
What´s wrong?
I follow a fews examples, but nothing works.
Console don't show any problem.
In order for your child routes to work, you will need a <router-view></router-view> in that component itself.
Using your code,
<div id="#app">
// your other code here
<router-view></router-view>
</div>
<template id="secondPage">
<h1>Second Page</h1>
<router-view></router-view>
</template>
Basically, add <router-view></router-view> inside the template of your second page.
How to import component in existing HTML page, below is the example. I tried with require but no luck.
`
<html>
<head>
<script src="//unpkg.com/vue#2.5.13/dist/vue.js"></script>
</head>
<body>
<div id="app">
<my-component></my-component>
</div>
<script>
import mycomponent from './components/mycomponent.vue'
var vm = new Vue({
el: '#app',
components: {
'my-component': mycomponent
}
})
</script>
</body>
</head>
</html>
`
The import line says unexpected identifier! what went wrong here, please help.
You need type=module on the script element, and the browser will treat the inline or external script as an ECMAScript module.
Here is how your code can be transformed
<html>
<head>
<script src="//unpkg.com/vue#2.5.13/dist/vue.js"></script>
</head>
<body>
<div id="app">
<my-component></my-component>
</div>
<script type="module">
import mycomponent from './components/mycomponent.vue'
var vm = new Vue({
el: '#app',
components: {
'my-component': mycomponent
}
})
</script>
</body>
</head>
</html>
