imported component into views not showing / VUE js - javascript

TLDR: Ive nested a component into a views folder and it wont show, I believe I have imported it correctly and think I'm missing something / any help here would be great
im importing a component into a views file which is then to be displayed via the vue router - the issue is the component or view does not show -
Oddly this code works if I ask the router to display the component as a stand alone, but not when I nest the component into the views file:
File structure is:
VIEWS FILE importing the component to be nested inside of it:
src/views/Contact.vue <<<< i imagine I have an issue here but I cannot seem to figure this out
<template>
<div class="contact_container">
<Contact/>
</div>
</template>
<script>
import Contact from '#/components/Contact.vue'
export default {
name: 'Contact',
components: {
Contact
}
}
</script>
Component file
src/components/Contact.vue
<template>
<div>
<h1>Welcome to the contact page</h1>
</div>
</template>
<script>
export default {
name: 'Contact',
data(){
return{
}
}
}
</script>
Views Router File:
src/router/index.js
import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'
import Contact from '../views/Contact.vue'
Vue.use(VueRouter)
const routes = [
{
path: '/',
name: 'Home',
component: Home
},
{
path: '/about',
name: 'About',
// route level code-splitting
// this generates a separate chunk (about.[hash].js) for this route
// which is lazy-loaded when the route is visited.
component: () => import(/* webpackChunkName: "about" */ '../views/About.vue')
},
{
path: '/contact',
name: 'Contact',
component: Contact
}
]
const router = new VueRouter({
routes
})
export default router
and finally App.veu
<template>
<div id="app">
<div id="nav">
<router-link to="/">Home</router-link> |
<router-link to="/about">About</router-link> |
<router-link to="/contact">Contact</router-link>
</div>
<router-view/>
</div>
</template>
/// UPDATED ///
In the code below - what does the name property do? 
(the code below is defining a component) 
<template>
    <div>
        <h1>Welcome to the contact page</h1>
    </div>
</template>
<script>
export default {
    name: 'Contact-Component', <<<< what does this do? 
    data(){
        return{
        }
    }
}
</script>
The reason why i'm a little lost here is because when we use this component we import it into another file using the below: 
import Contact from '../views/Contact.vue'
In that process we have defined the component as Contact (so it is not referenced by its name any more) .... so why did we define a name?
If there is any documentation on this that would be amazing and while it seems like a silly question (and probably is) it is distracting me with curiosity...
Thanks for any help -

change your code with this
<template>
<div class="contact_container">
<Contact/>
</div>
</template>
<script>
import Contact from './components/Contact.vue'
export default {
name: 'Contact',
components: {
"Contact":contact
}
}
</script>

The name is used to allow the component to recursively invoke itself in its template. It also helps when debugging as it allows for a more helpful error message.
Have a read over this to get a better idea: https://v2.vuejs.org/v2/api/#name

You have to let the app know it's a Vue component:
<script lang="js">
import Vue from 'vue';
export default Vue.extend({
name: 'Contact',
...
});

Add route to Vue.js router while app is running

I'm currently building an app and I would like to add extensions to this app. These extensions should have their own Vue components and and views (and thus also routes). I don't want to rebuild the app but instead add the new views and routes dynamically. Is there a good way to do that with Vue 2?
In the following I added the files that I hope makes this question a bit more comprehensible. The router/index.js contains the basic structure and is added to the main.js file in the regular fashion. During the load of the app.vue the new routes should be loaded and appended to the already existing ones.
router
import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'
Vue.use(VueRouter)
const routes = [
{
path: '/',
name: 'Home',
component: Home
},
{
path: '/about',
name: 'About',
// route level code-splitting
// this generates a separate chunk (about.[hash].js) for this route
// which is lazy-loaded when the route is visited.
component: () => import(/* webpackChunkName: "about" */ '../views/About.vue')
}
]
const router = new VueRouter({
mode: 'history',
base: process.env.BASE_URL,
routes
})
export default router
main.js
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
Vue.config.productionTip = false
new Vue({
router,
store,
render: h => h(App)
}).$mount('#app')
App.vue
<template>
<div id="app">
<div id="nav">
<router-link to="/">Home</router-link> |
<router-link to="/about">About</router-link> |
<router-link to="/test">Test</router-link>
</div>
<router-view/>
</div>
</template>
<script>
// # is an alias to /src
import TestView from '#/views/Test.vue'
export default {
name: 'Home',
components: {},
created() {
<add route to router>({
component: TestView,
name: "Test",
path: "/test"
})
}
}
</script>
I used the phrase <add route to router> to demonstrate the way I would like to add the route. After the route is added the user should be able to directly navigate to the new view using <router-link to="/test">Test</router-link>.
Any help would be appreciated.
Use addRoute to add routes at runtime. Here is the explanation for this method from the docs:
Add a new route to the router. If the route has a name and there is already an existing one with the same one, it overwrites it.
Import the router into App.vue to use it:
App.vue
<script>
import router from './router/index.js';
import TestView from '#/views/Test.vue'
export default {
created() {
router.addRoute({
component: TestView,
name: "Test",
path: "/test"
})
}
}
</script>

How do I call a global function in a vue.js child component?

The global function init() outputs a console log when the screen is loaded. However, clicking the child component button does not re-enable the init() function.
How can I call the global function init() when I click a button in my child's component?

]
})
function init() {
console.log('load inti()')
}
init();
$('#btn_link').click(function(){
init();
});
The whole idea of js modules is to stop you having, or supposedly needing, a global scope. People sometimes suggest a workaround of adding your global functions to the Vue object, which strikes me as a cure worse than the disease. My answer to this is to provide one global object in the root of your vue app, put your functions inside, then inject it into any component that needs it.
As it says in the comments, don't use jquery with Vue. Your event handler should be in the methods of the component that contains the button.

Vue router does not render/mount root path component

i am making a page with vue, vue-router and laravel, the problem, when i enter in localhost/myproject/public_html/, the Home component is not rendered in the router-view, if i click in the router link to the Service component, it render the content normally, and when i click to the home path it render the home component content, so why this happens? this is my app.js structure
import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)
import App from './views/App'
import Home from './views/Home'
import Service from './views/Service'
const router = new VueRouter({
mode: 'history',
routes: [
{
path: '/',
name: 'home',
component: Home
},
{
path: 'servicios',
'name' : 'services',
component: Service
}
],
});
const app = new Vue({
el: '#app',
components : { App },
router,
});
this is my App.vue
<template>
<div>
Hola
<router-link :to="{ name : 'services' }">
ir a servicios
</router-link>
<router-view>
</router-view>
</div>
</template>
<script>
import PageLogo from '../components/PageLogo'
import Loading from '../components/Loading'
export default {
mounted : function(){
console.log(this.$router.currentRoute.path)
},
components : {
'page-logo' : PageLogo,
'loading' : Loading
},
methods : {
ajaxOver : function() {
}
}
}
</script>
this is my Home.vue
<template>
<div class="row">
Home page
<router-link :to="{ name : 'services' }">
go to services
</router-link>
</div>
</template>
<script>
export default {
mounted: function() {
console.log('hola')
}
}
</script>
and this is Service.vue
<template>
<div>
Services page
<router-link :to="{ name : 'home' }">
go to home
</router-link>
</div>
</template>
<script>
export default {
mounted : function(){
console.log('services')
}
}
</script>
so how can i solve this? if i reload the page in any route, the component should be mounted, but in the vue router is not being displayed, so the component is not mounted.
Edit:
As requested, in App.vue the log is /myproject/public_html/
I've never used Laravel before, but I think you're looking for base.
Vue docs:
type: string
default: "/"
The base URL of the app. For example, if the entire single page application is served under /app/, then base should use the value "/app/".
Since you're serving your project at localhost/myproject/public_html/, vue is seeing /myproject/public_html/ instead of /.
You can change this by adding the base route to the vue-router constructor.
const router = new VueRouter({
mode: 'history',
base: '/myproject/public_html/',
...
}

VueJS named routes not working

I try to work with named routes in a Vue app.
Exactly the same setup works totally fine in an other Vue project.
If I click on a named router-link, the just disappears.
If I check the element in the browser, there is an empty comment at the place, where the section should be.
The console isn't showing any errors.
Has anyone seen something similar?
Thank's for every help!
Code:
index.js
import Vue from 'vue';
import Router from 'vue-router';
import Home from '#/components/views/home';
import AskQuestion from '#/components/views/ask-question';
import AddQuestion from '#/components/views/add-question';
import CompleteQuestions from '#/components/views/complete-questions';
import Survey from '#/components/views/survey';
Vue.use(Router);
export default new Router({
routes: [
{
path: '/',
name: 'Home',
component: Home
},
{
path: '/ask-question',
name: 'AskQuestion',
component: AskQuestion
},
{
path: '/add-question',
name: 'AddQuestion',
component: AddQuestion
},
{
path: '/complete-questions/:surveyId',
name: 'CompleteQuestions',
component: CompleteQuestions
},
{
path: '/survey/:surveyId',
name: 'Survey',
component: Survey
}
]
});
HTML
<router-link :to="{name: 'survey', params: {surveyId: survey.id}}">
<p class="viewQuestions">View questions</p>
</router-link>
App.vue
<template>
<div id="app">
<navigation></navigation>
<router-view/>
</div>
</template>
<script>
import Navigation from '#/components/generel/navigation';
export default {
name: 'app',
components: {
Navigation
}
};
</script>
<style src="./assets/scss/_general.scss" lang="scss"></style>
in route config , set history mode and then go to your link and click that LINK , and then go check URL address bar
export default new VueRouter({
mode:'history',
......
});
for example if you click on this
<router-link :to="{ name: 'home' }"> Home </router-link>
and your rute is
{
path:'/home',
component:Home,
name:'home'
}
if your route workin well , you must see this url in browser address bar
https://localhost/home

Template not being displayed on click on Vue link

I'm creating a Laravel website that will be a single page application. I'm new to VueJS even if I have experience with javascript in general.
I need to display several routes, such as /blog/new, /blog/:id, /blog/edit, etc. /blog itself is defined by Laravel, and works as the blog index.
I installed vue-router, and tried to follow some examples I saw but nothing happens:
app.js
import './bootstrap';
import Vue from 'vue';
import VueRouter from 'vue-router';
const blogIndex = { template: require('./components/blog/index.vue') };
const blogNew = { template: require('./components/blog/new.vue')};
const routes = [
{
path: '/blog',
component: blogIndex,
name: 'blog-index'
},
{
path: '/blog/new',
component: blogNew,
name: 'blog-new'
}
];
const router = new VueRouter({
routes,
mode: "history"
});
Vue.use(VueRouter);
Vue.component('example', require('./components/Example.vue'));
Vue.component('navbar', require('./components/Navbar.vue'));
Vue.component('blog_index', require('./components/blog/index.vue'));
console.log(testvar);
const app = new Vue({
router
}).$mount('#app');
components/blog/index.vue
<template>
<div>
<h1>Blog index</h1>
<router-link :to="{ name: 'blog-new' }">New article</router-link>
<router-view></router-view>
</div>
</template>
<script>
export default {
mounted() {
console.log('blog#index mounted');
}
}
</script>
components/blog/new.vue
<template>
<h2>Here is blog/new y'all</h2>
</template>
<script>
export default {
mounted() {
console.log('blog#new mounted');
}
}
</script>
So far, the only thing that works is my address bar that gets modified, but the template itself doesn't seem to be loaded (I go from /blog to /blog/new).
I've seen that I need add <router-view></router-view> in my html file, but this triggers an error and blocks VueJS's display.
My question is: what am I missing, or what did I do wrong?
Thank you in advance
You need to use <router-view></router-view> in your main App.vue file, which is the part that new routes are loaded into.
<template>
<router-view></router-view>
</template>
You currently state you have this in components/blog/index.vue - which I believe is just for your nested routes. https://router.vuejs.org/en/essentials/nested-routes.html
