Difference between router-link and RouterLink in Vue - vue.js

When using Vue Router, I found that I could use <router-link> as well as RouterLink to achieve the same result, i.e. navigate between different routes.
Similarly, there's <router-view> as well as RouterView component.
Following two code examples give me the same result:
With <router-link> and <router-view>:
<template>
<router-link to="/">Home</router-link>
<router-link to="/about">About</router-link>
<hr />
<router-view></router-view>
</template>
With <RouterLink> and <RouterView>:
<script setup>
import { RouterLink, RouterView } from "vue-router";
</script>
<template>
<RouterLink to="/">Home</RouterLink>
<RouterLink to="/about">About</RouterLink>
<hr />
<RouterView />
</template>
Question
What is the difference between <router-link> and RouterLink (and between <router-view> and RouterView?)
I couldn't find anything on Vue Router docs. Searching for RouterView or RouterLink doesn't show any results related to them. Docs only mention <router-link> and <router-view>.
P.S. Scaffolding a new Vue project with npm init vue#latest command uses RouterLink and RouterView components instead of router-link and router-view.

It's the same components, just with different cases, in vue it's recommended to use the PascalCase syntax as mentioned here :
In SFCs, it's recommended to use PascalCase tag names for child components to differentiate from native HTML elements. Although native HTML tag names are case-insensitive, Vue SFC is a compiled format so we are able to use case-sensitive tag names in it. We are also able to use /> to close a tag.

They are the same thing. Any component can be used either by writing its name as PascalCase or kebab-case.

One is the component name and one is the vue class. I don't think there is a difference. If you would create your own component e.g. MyComponent.vue, you can also use <MyComponent> or <my-component>

Insert 2 components in nuxt.js page

i'm new of this framework :(
the problem is here because i've tried to put the component in another page and work it.
It sign error the component
this is my index.vue page
If you're using nuxt2.0, you should wrap them in a container but this is not needed in nuxt3.0.
<template>
<main>
<navbar />
<slideshow />
</main>
</template>
If this is nuxt2.0, then you should also import the component and register it but you haven't done it here. The path you've given to the component is not correct also.
<script>
import Slideshow from '~/components/slideshow.vue';
export default {
components: { Slideshow }
}
</script>
You need to wrap the into a div or any other tag (to not have multiple tags at the root of the template) like that
<template>
<div>
<navbar></navbar>
<slideshow></slideshow>
</div>
</template>
And you can also skip the import part because Nuxt is already doing that for you as explained here: https://nuxtjs.org/tutorials/improve-your-developer-experience-with-nuxt-components/

How to use Vue I18n translation in component attribute/property

How do I translate the passed-in attribute/property of a component? For instance, I have a card component with a title and description prop defined like this.
<!-- my-card component -->
<template>
<div>
<h2>{{title}}</h2>
<span>{{description}}</span>
</div>
</template>
<script>
export default {
props: {
title: String,
descritpion: String
}
}
</script>
Then using the my-card component in another page/component like this
<template>
<div>
<header>Page header</header>
<my-card :title="the best card title" :description="the best description" />
<footer>Page footer</footer>
</div>
</template>
How do I us vue I18n to translate the component props?
<template>
<div>
<header>Page header</header>
<my-card :title="{{ $t('myCard.title')}}" :description="{{$t('myCard.description')}}" />
<footer>Page footer</footer>
</div>
</template>
I can't seem to get the translation to work with passed-in props.
PS: I know I could add the translation in the place I defined my-card component but the issue here is that the components are third-party components from NPM library.
I know some packages in React.js has this feature.
Just bind the translation without using {{}} :
<my-card :title="$t('myCard.title')" :description="$t('myCard.description')" />
You can use I18n translation in component props like this.
<my-card
:title="$t('myCard.title')"
:description="$t('myCard.description')"
/>

how can i pass registered vue component as prop to a component

Need to pass component to child component, using props or you have better way to solve this problem
I registered component needed to pass globally or just registered this component locally. But these solutions can't solve my problem.
Here is my code to register component needed to pass locally:
a.vue html
<dropdown :icon="UserIcon"></dropdown>
a.vue js
components: {'dropdown', Dropdown, 'icon-user': UserIcon}
dropdown.vue html
<div class="dropdown"><icon></icon></div>
dropdown.vue js
props: ['icon']
UserIcon.vue
<i class="user-icon"></i>
the browser reminds me that icon is unknown custom element. It seems like vue does not support this way to use component, doesn't it?
I solve this problem using slot.
and there is another question comes...
a.vue
<dropdown><template v-slot:icon><icon-user></icon-user></template></dropdown>
dropdown.vue
<div class="dropdown"><slot name="icon"></slot></div>
But icon-user component didn't show...
and I did this work, cuz I remove the name attribute of slot.
a.vue
<dropdown><template><icon-user></icon-user></template></dropdown>
dropdown.vue
<div class="dropdown"><slot></slot></div>

v-if on a component template tag

From the docs:
Because v-if is a directive, it has to be attached to a single
element. But what if we want to toggle more than one element? In this
case we can use v-if on a element, which serves as an
invisible wrapper. The final rendered result will not include the
element.
But on my template in my component:
<template v-if="false">
<div>
....
</div>
</template>
But the component still renders.
I ask because I want a hook on the component so if v-if is true, I can do some code in beforeMounted and beforeDestroyed if false.
If I undestood what are you doing...
You're putting v-if int the template tag ina .vue file right?
Like this
// component.vue
<template v-if="false">
<div>
My Component
</div>
</template>
<script>
export default {
name: 'my-component'
};
</script>
<styles>
</styles>
Right?
If YES, you are doing it wrong.
The template there is a tag for Webpack Vue Loader to load the component template.
So the if must go inside the template tag.
// component.vue
<template>
<div v-if="false">
My Component
</div>
</template>
<script>
export default {
name: 'my-component'
};
</script>
<styles>
</styles>
If you need to "hide" multiple elements, just encapsulate into another div.
As Lucas Katayama said, you cannot use v-if inside SFC, but another way to hide you component is use v-if on this component in its parent component.
Your reference to the docs is correct, you can use a v-if on a template tag. However, I believe conditionals on the top-level <template> in a Single File Component are ignored.
To achieve the effect showed in the docs (conditional render a template) that template needs to be within the top-level template section.
Example:
<script>
// your script section
</script>
<template>
<template v-if="false">
<div>
....
</div>
</template>
</template>
<style>
// your style section
</style>

Aurelia custom element without outer node

Is it possible to let Aurelia render a custom element without the capsulating component node? Or replace the custom-element node with its content?
Example:
app.html
<template>
<require from = "./components/custom-component.html"></require>
<custom-component></custom-component>
</template>
app.ts
export class App {
}
custom-component.html
<template>
<p>This is some text from dynamic component...</p>
</template>
Result
Based on this example: Is it possible with aurelia to render the <p> element from the component as direct child of the <body>, so that there will be no custom-component-node?
Use the containerless attribute on your component.
example: https://gist.run/?id=8e57000c7b8423dc0246a7006d90ba79
you can also decorate your custom components with the containerless() decorator.
