I have got a fresh install of Laravel Mix and I am trying to setup lazy loading components in the project. I have got the correct setup with the babel plugin 'syntax-dynamic-import' so the import statement in app.js works as expected. The issue occurs when I attempt to use the lazy loaded component with vue-router.
My app.js file looks like this:
require('./bootstrap');
import Vue from 'vue';
import VueRouter from 'vue-router';
Vue.use(VueRouter);
const EC = () => import(/* webpackChunkName: "example-component" */ './components/ExampleComponent.vue');
const router = new VueRouter({
mode: 'history',
routes: [
{ path: '/', component: EC }
]
});
const app = new Vue({
router,
el: '#app'
});
and my welcome.blade.php file looks like this:
<!doctype html>
<html lang="{{ app()->getLocale() }}">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="csrf-token" content="{{ csrf_token() }}">
<title>Laravel</title>
<link href="{{ asset('css/app.css') }}" rel="stylesheet">
<base href="/" />
</head>
<body>
<div id="app">
<h1>Base title</h1>
<example-component></example-component>
</div>
<script src="{{ asset('js/app.js') }}"></script>
</body>
</html>
So I just trying to land on the root route and display the Example Component. The example component is included in the welcome.blade.php file.
I am receiving this error in the console:
[Vue warn]: Unknown custom element: <example-component> - did you register the component correctly? For recursive components, make sure to provide the "name" option.
(found in <Root>)
I think I am missing something simple, any advice is appreciated.
First, i think you are mixing routes concepts with core components vue concepts...
Try loading the component directly in your vue app...
const app = new Vue({
router,
el: '#app',
components: {
'example-component': () => import('./components/ExampleComponent.vue')
}
});
Component loading is done with <component>
<component v-bind:is="currentTabComponent"></component>
Check the docs, for more info on dynamic components: https://v2.vuejs.org/v2/guide/components-dynamic-async.html
#Erubiel answer did work but it still quite wasn't the setup I wanted. As I am trying to use vue-router I needed to update the view by removing the explicit call to the component and adding the tag in the welcome.blade.php file. This now means my routes are injected into that space. The updated area is:
...
<body>
<div id="app">
<router-view></router-view>
</div>
<script src="{{ asset('js/app.js') }}"></script>
</body>
...
The problem is in the scss splitting in Vue and using mix.scss() both. Laravel mix when having both creates a css file with manifest js file content in it. which is definitely a bug. which the community mentions a bug from Webpack and will be resolved in webpack 5. But If you use only code splitting in Vue and have the default app.scss file imported to main Vue component like this(not in scope), so each other component will get the styling properly
// resources/js/components/app.vue
<template>
<!-- Main Vue Component -->
</template>
<script>
// Main Script
</script>
<style lang="scss">
#import '~#/sass/app.scss';
</style>
and the webpack.mix.js file will have no mix.scss function to run only a single app.js file. here is my file.
// webpack.mix.js
const mix = require('laravel-mix')
mix.babelConfig({
plugins: ['#babel/plugin-syntax-dynamic-import'] // important to install -D
})
mix.config.webpackConfig.output = {
chunkFilename: 'js/[name].bundle.js',
publicPath: '/'
}
mix
.js('resources/js/app.js', 'public/js')
.extract(['vue'])
.webpackConfig({
resolve: {
alias: {
'#': path.resolve('resources/') // just to use relative path properly
}
}
})
Hope this solves everyone's question
Note: Can we write vue.js large application without using any compiler for code like currently i see all example use webpack now to make vue.js code compatible for browser .
I want make vue.js application without webpack and without using .vue extension. Is it possible? if it is possible, can you provide a link or give sample how to use routing in that case.
As we make component in .vue extension can be make component in .js extension and use application as we do in angular 1 where we can make whole app without any trans-compiler to convert the code.
Can be done that in html , css , js file only and no webpack sort of thing.
What i have done .
index.js
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<title>vueapp01</title>
</head>
<body>
<div id="app"></div>
<!-- built files will be auto injected -->
</body>
</html>
main.js this file added in webpack load time
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
components: { App },
template: '<App/>'
})
App.vue
<template>
<div id="app">
<img src="./assets/logo.png">
Hello route
Helloworld route
{{route}}
<router-view/>
<!-- <hello></hello> -->
</div>
</template>
<script>
export default {
name: 'App',
data () {
return {
route : "This is main page"
}
}
}
</script>
router
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '#/components/HelloWorld'
import Hello from '../components/Hello'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'HelloWorld',
component: HelloWorld
},
{
path: '/hello',
name: 'Hello',
component: Hello
}
]
})
I have done something like this . Can we do this by just html , css , js file only with not webpack to compile code . Like we do in angular 1 .
Thanks
As stated in this jsFiddle: http://jsfiddle.net/posva/wtpuevc6/ , you have no obligation to use webpack or .vue files.
The code below is not from me and all credit goes to this jsFiddle creator:
Create an index.html file:
<script src="https://npmcdn.com/vue/dist/vue.js"></script>
<script src="https://npmcdn.com/vue-router/dist/vue-router.js"></script>
<script src="/js/Home.js"></script>
<script src="/js/Foo.js"></script>
<script src="/js/router.js"></script>
<script src="/js/index.js"></script>
<div id="app">
<router-link to="/">/home</router-link>
<router-link to="/foo">/foo</router-link>
<router-view></router-view>
</div>
Home.js
const Home = { template: '<div>Home</div>' }
Foo.js
const Foo = { template: '<div>Foo</div>' }
router.js
const router = new VueRouter({
mode: 'history',
routes: [
{ path: '/', component: Home },
{ path: '/foo', component: Foo }
]
})
index.js
new Vue({
router,
el: '#app',
data: {
msg: 'Hello World'
}
})
Appreciate the framework...
Just a sidenote: .vue files are really awesome, you should definitely try them if not using them is not a requirement
I have started learning vue.js also and I am not familiar with webpack and stuff and I also wanted to still separate and use .vue files as it makes management and code cleaner.
I have found this library:
https://github.com/FranckFreiburger/http-vue-loader
and a sample project using it:
https://github.com/kafkaca/vue-without-webpack
I am using it and it seems to work fine.
You perfectly can, but with a lot of disadvantages. For example: you cannot easily use any preprocessor, like Sass or Less; or TypeScript or transpile source code with Babel.
If you don't need support for older browser, you can use ES6 modules today. Almost all browsers support it. See: ES6-Module.
But Firefox doesn't support dynamic import(). Only Firefox 66 (Nightly) support it and need to be enabled.
And if that wasn't enough, your web application will not be indexed. It's bad for SEO.
For example, Googlebot can craw and index Javascript code but still uses older Chrome 41 for rendering, and it's version don't support ES6 modules.
If that are not disadvantages for you, then you can do this:
Remove any thirty party library import like Vue, VueRouter, etc. And include those in the index.html file using script tags. All global variables are accesible in all es6 modules. For example, remove this line from main.js and all .vue files:
import Vue from 'vue';
And add this line in your index.html:
<script src="https://npmcdn.com/vue/dist/vue.js"></script>
Rewrite all .vue files and change file extension to .js. For example, rewrite something like this:
<template>
<div id="home-page">
{{msg}}
</div>
</template>
<script>
export default {
data: function() {
return { msg: 'Put home page content here' };
}
}
</script>
<style>
#home-page {
color: blue;
}
</style>
to something like this:
let isMounted = false; /* Prevent duplicated styles in head tag */
export default {
template: `
<div id="home-page"> /* Put an "id" or "class" attribute to the root element of the component. Its important for styling. You can not use "scoped" attribute because there isn't a style tag. */
{{msg}}
</div>`,
mounted: function () {
if (!isMounted) {
let styleElem = document.createElement('style');
styleElem.textContent = `
#home-page {
color: blue;
}
`;
document.head.appendChild(styleElem);
isMounted = true;
}
},
data: function () {
return {
msg: 'Put home page content here'
};
}
}
It is all. I put an example in this link
P.S. Text editing without syntax highlighting can be frustrating. If you use Visual Studio Code you can install Template Literal Editor extension. It allows editing literal strings with syntax highlight. For styles select CSS syntax, and for templates HTML syntax. Unknown tag in HTML are highlighted differently. For solve this, change the color theme. For example, install Brackets Dark Pro color theme or any theme do you like.
Regards!
For sure you can. We did a project with Vue, and we had couple of problems during compiling .vue files.
So we switched to structure with three separate files.
But be aware that you need webpack anyway. The idea of Vue was to split huge projects into components, so using template inside .js file it's pretty normal.
So take a look at
html-loader
And
css-loader
Using these modules you can write something like this:
component.js
// For importing `css`. Read more in documentation above
import './component.css'
// For importing `html`. Read more in documentation above
const templateHtml = require('./component.html')
export default {
name: 'ComponentName',
components: { /* your components */ },
mixins: [/* your mixins */ ],
template: templateHtml,
computed: .....
}
component.css
#header {
color: red
}
component.html
<div id="header"></div>
BUT
You need to know that HTML file should be written in the same way as I you will have it in template property.
Also, take a look at this repo, maybe you will find something useful here
Vue-html-loader. It is a fork from html-loader by Vue core team.
In vuejs 3 you you can do it in an ES6 modular fashion (no webpack or other tools required):
index.html
<!DOCTYPE html>
<html>
<head>
<script type="importmap">
{
"imports": {
"vue": "https://unpkg.com/vue#3.0.11/dist/vue.esm-browser.js",
"vue-router": "https://unpkg.com/vue-router#4.0.5/dist/vue-router.esm-browser.js",
"html" : "/utils/html.js"
}
}
</script>
<script src="/main.js" type="module"></script>
</head>
<body>
<div id="app"></div>
</body>
</html>
main.js
import { createApp, h } from 'vue';
import {createRouter, createWebHashHistory} from 'vue-router';
import App from './components/App.js';
const routes = [//each import will be loaded when route is active
{ path: '/', component: ()=>import('./components/Home.js') },
{ path: '/about', component: ()=>import('./components/About.js') },
]
const router = createRouter({
history: createWebHashHistory(),
routes,
})
const app = createApp({
render: () => h(App),
});
app.use(router);
app.mount(`#app`);
components/App.js
import html from 'html';
export default {
name: `App`,
template: html`
<router-link to="/">Go to Home</router-link>
<router-link to="/about">Go to About</router-link>
<router-view></router-view>
`};
components/Home.js
import html from 'html';
export default {
template: html`
<div>Home</div>
`};
components/About.js
import html from 'html';
export default {
template: html`
<div>About</div>
`};
utils/html.js
// html`..` will render the same as `..`
// We just want to be able to add html in front of string literals to enable
// highlighting using lit-html vscode plugin.
export default function () {
arguments[0] = { raw: arguments[0] };
return String.raw(...arguments);
}
Notes:
Currently (04/2021) importmap works only on chrome (firefox in progress). To make the code compatible with other browsers also, just import (on each .js file) the dependencies directly from the urls. In this case though vue-router.esm-browser.js still imports 'vue', so you should serve an updated version of it, replacing import { .... } from 'vue' with import { .... } from 'https://unpkg.com/vue#3.0.11/dist/vue.esm-browser.js'
To avoid waterfall loading effect, you can add <link rel="modulepreload" href="[module-name]"> entries to index.html to start preloading some or all modules asynchronously before you need them.

I am using VueJS Router, but the router is not loading the components.
I have About.vue and Contact.vue just with tag to test - following is how it looks like :
<template>
<div>
<h1>Contact page. Welcome baby!</h1>
</div>
</template>
This is App.vue with three router-links and router-view.
<template>
<div>
<h1>Routing</h1>
<router-link to="/">Home</router-link>
<router-link to="/about">About</router-link>
<router-link to="/contact">Contact</router-link>
<router-view></router-view>
</div>
</template>
This is main.js (the paths of importing files are correct)
import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import {routers} from './router'
Vue.use(VueRouter);
let router = new VueRouter({mode: 'history', routers});
new Vue({
el:'#app',
router,
components: {
'app-home' : App
}
});
This is the JS file for the router. router.js (paths are correct)
import About from './About.vue'
import Contact from './Contact.vue'
import Home from './App.vue'
export const routers=[
{
path: '/' , component: Home
},
{
path:'/about',component:About
},
{
path:'/contact',component:Contact
}
]
And, this is index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>router</title>
</head>
<body>
<div id="app">
<app-home></app-home>
</div>
<script src="/dist/build.js"></script>
</body>
</html>
When I load the page, the main page looks like the following :
and when I click the each nav, nothing is changed from the main page except URL.
URL becomes
http://localhost:8080/contact
http://localhost:8080/about
but not loading the component I imported.
If you need more information to give advice, feel free to ask more.
And if you have any clue of this issue, I appreciate if you share here.
Thank you.
The object key VueRouter is expecting is called routes, you are passing it routers.
Try this...
let router = new VueRouter({mode: 'history', routes: routers});
Alternatively, rename your "routers" variables to "routes". Eg
export const routes=[
and
import {routes} from './router'
// snip
let router = new VueRouter({mode: 'history', routes });
In my case I had to create a new Vue project (vue create Project) with "Manually select features"; then I had to mark "Router".
Previously I've created a project with defaults and I've installed router separately (npm install vue-router) - but at the end the routing didn't load the components.
ps. I use:
npm 6.14.6
nodejs v12.18.3
#vue/cli 4.5.4
I was having the same symptoms as the OP but using netlify and gridsome (which uses vue.js. In my case it was a incorrectly tagged contact form that was the cause.
I need to set up vue router in my vue ja 2 application .I am not using vue cli just the cdn for vue Js .I am not able to find a way of how to set up vue router with cdn.can anyone suggest any documentation or the technique of how to achieve that ??
Any help would be much appreciated
Here's a bare bones example to help get going:
<html>
<head>
<script src="https://unpkg.com/vue"></script>
<script src="https://unpkg.com/vue-router#2.0.0/dist/vue-router.js"></script>
</head>
<body>
<div id="app">
<p><router-link to="/page1">Go to Page 1</router-link></p>
<p><router-link to="/page2">Go to Page 2</router-link></p>
<p><router-view></router-view></p>
</div>
<script>
var PageTwoComponent = Vue.component('comp2',{
template: '<p>Component Two</p>'
})
var PageOneComponent = Vue.component('comp1',{
template: '<p>Component One</p>'
})
const routes = [
{path: '/page1', component: PageTwoComponent},
{path: '/page2', component: PageOneComponent}
]
const router = new VueRouter({
routes
})
var app = new Vue({
router
}).$mount('#app')
</script>
</body>
</html>
I created a fresh project using the vue-cli command:
vue init webpack myapp
I am trying to add the vue-router to handle routes but I am having trouble.
Here is my main.js:
import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App'
var Foo = Vue.extend({
template: '<p>This is foo!</p>'
})
var Bar = Vue.extend({
template: '<p>This is bar!</p>'
})
Vue.use(VueRouter)
const router = new VueRouter()
router.map({
'/foo': {
component: Foo
},
'/bar': {
component: Bar
}
})
router.start(App, '#app')
/* eslint-disable no-new */
new Vue({
el: 'body',
components: { App }
}).$mount('#app')
Here is my index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>shivaminyanim.com</title>
</head>
<body>
<app></app>
<!-- built files will be auto injected -->
</body>
</html>
And here is my App.vue:
<template>
<div id="app">
<h1>Hello App!</h1>
<p>
<!-- use v-link directive for navigation. -->
<a v-link="{ path: '/foo' }">Go to Foo</a>
<a v-link="{ path: '/bar' }">Go to Bar</a>
</p>
<!-- route outlet -->
<router-view></router-view>
</div>
</template>
Whatever I do I can't seem to figure out how to get it to work. Right now I don't get any console errors but the browser just displays
Cannot GET /foo
for every route respectively.
I am currently using
"vue": "^1.0.21"
"vue-router": "^0.7.13",
How can I get started with vue-router?
You need to add router to your bootstrapped Vue instance in main.js. For example like this:
Vue 2.0 and Vue-router 2.0
new Vue({
router,
el: '#app',
render: h => h(App)
})
Vue 1.0 and Vue-router < 2.0
router.start({
components: { App }
}, '#app')
