vuerouter editing link and do I store the state? - vue.js

I am using vuerouter really for the first time and I am trying to dynamically add a url name to the hyperlink of the route. Not sure what I am doing here, {{message}} would show the name and I am trying to concatenate that to the existing url--what am I doing wrong?
secondly, because these pages are dynamically generated, would I use vuex to store the state--? so that others could see the pages--?
const Home = { template: '<div>Home</div>' }
const Foo = {
template: '<div>Foo {{n }}, {{b}}</div>',
props: ['n', 'b']
}
const router = new VueRouter({
mode: 'history',
routes: [
{ path: '/', component: Home },
{ path: '/', component: Foo, props: route => ({
})}
]
})
new Vue({
router,
el: '#app',
data: {
message:''
}
})

<body class="container">
<div id="app">
<h2>Generator</h2>
<input v-model="message" placeholder="Enter Plan Year"> {{message}} Year<br><br>
These pages are automatically generated:<br>
<strong> CardMain_{{message}}.html</strong><br>
<strong> Card_{{message}}.html</strong><br>
<strong> state_{{message}}.html</strong><br>
<strong> Log_{{message}}.html</strong><br>
<strong> Log2_{{message}}.html</strong><br><br>
<router-link to="/">/home</router-link>
<router-link to="url/+'{{message}}+'">eCard</router-link>
<router-link to="/foo/5/5">Directory</router-link>
<router-view></router-view>
<p><button class="btn btn-primary">Generate</button></p>
</div>

In order to generate the url, what you want is to use a v-bind on the route, you can do this by replacing the "to" with ":to"
Once you have that, the content of the attribute ":to" behaves as if it was javascript and you have access to all the properties of the vue component so you can just do:
<router-link to="'url/' + message">eCard</router-link>
However this route hasnt actually been registerd so it will not load anything.
Instead you may want to register a route that accepts a parameter
{ path: '/url/:id', name: 'ecard', component: eCardComponent , props: true }
In this way you can call your route as
<router-link :to="{ name: 'ecard', params:{ id: message } }">eCard</router-link>
Then you can do whatever you need in that component, like loading info from a database for that particular id.
Additionally, Vuex only works on the current tab (unless you use some code to syncronize it with the localstorage, like this example) and even then it would not persit it across machines.
const Home = { template: '<div>Home</div>' }
const eCardComponent = { template: '<div>Ecard :{{id}}</div>', props:['id'] }
const Foo = {
template: '<div>Foo {{n }}, {{b}}</div>',
props: ['n', 'b']
}
const router = new VueRouter({
routes: [
{ path: '/', component: Home },
{ path: '/', component: Foo, props: route => ({
})},
{ path: '/url/:id', name:'ecard', component: eCardComponent, props: true },
]
})
new Vue({
router,
el: '#app',
data: {
message:''
}
})

How to use vue-select in a simple HTML page?

It is my first "try" with Vue + vue-select.
I have imported Vue and vue-select like it is explained in the vue-select documentation.
And my first try is this simple HTML page :
<!DOCTYPE html>
<html lang="en">
<head>
<!-- include VueJS first -->
<script src="https://unpkg.com/vue#latest"></script>
<!-- use the latest vue-select release -->
<script src="https://unpkg.com/vue-select#latest"></script>
<link
rel="stylesheet"
href="https://unpkg.com/vue-select#latest/dist/vue-select.css"
/>
</head>
<body>
<div id="app">
<h1>Vue Select</h1>
<v-select :options="options"></v-select>
</div>
<script>
Vue.component("v-select", VueSelect.VueSelect);
new Vue({
el: "#app",
data: {
options: ["foo", "bar", "baz"],
},
});
</script>
</body>
</html>
When I try this page, I have these errors in the console :
What it is wrong in this first try? When I understand this first example, it will be easier for the rest.
I just checked your code and seems this issue is due to the vue version you are using. I just used version 2.* and it is working.
Demo :
Vue.component("v-select", VueSelect.VueSelect);
new Vue({
el: "#app",
data: {
selected: 'foo',
options: ["foo", "bar", "baz"]
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.6.11/vue.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue-select/3.10.3/vue-select.js"></script>
<link rel="stylesheet" href="https://unpkg.com/vue-select/dist/vue-select.css"/>
<div id="app">
<h1>Vue Select</h1>
<v-select :options="options" v-model="selected"></v-select>
</div>
Update : Here is the Vue 3 version of v-select
const { createApp } = Vue
const { createVuetify } = Vuetify
const vuetify = createVuetify()
const app = createApp({
template: '#app-template',
data: () => ({
items: ['Foo', 'Bar', 'Fizz', 'Buzz'],
}),
}).use(vuetify).mount('#app')

Vue.js x-template works well, but cannot be resolved in IDE

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>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Router_App</title>

<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>

<div id="app">
<nav>
<router-link to="/top">Top page</router-link>
<router-link to="/users">User page</router-link>
</nav>
<router-view></router-view>
</div>
<script type="text/x-template" id="user-list">
<div>User page</div>
</script>
<script>
let router = new VueRouter({
routes: [

}
},

}
}

How to use a plugin for markdown-it-vue library?

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

index.html
<!DOCTYPE html>
<head>
<title>Hello World</title>
</head>
<body>
<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>
<div id="app">
<div>
{{ msg }}
</div>
<markdown-it-vue :content="msg" class="md-body"></markdown-it-vue>
</div>
<script src="app.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:

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">

<script>
//setup routing using SPA VUE interface
Vue.use(VueRouter);
const routes = [
{ path: '/', component: dashboard },
{ path: '/reviews', component: reviews }
]
const router = new VueRouter({

var app = new Vue({

</script>
}
side-navigation:

<template id="side-navigation">

<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'

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.
