Laravel local vue component registration - laravel

I know I can register global components in the file located in resources/js/app.js.
I know when I do this I can use these component in any place (because they are global).
But I don't want that. I have a big application and different functionalities solved in different routes. So I don't want the whole components available in all my views.
How can I register locally the components I want to be available only in one view?
Thanks

Vue js register component in local:
step-1 ) storing the component object in a variable:
var demo = {
data: function() {
return {
message: 'This is a local components.'
};
},
template: `
<div>
<h1>Component: {{ message }}</h1>
</div>
`
};
Step-2 ) Add a component property with the components that we want to register locally.
new Vue({
el: '#app1',
components: { /*Here we have added property*/
'demo': demo
}
});
Step-3 ) Template
<div id="app1">
<demo></demo>
</div>
*Notice: This property should be an object and contain key-value pairs of tag names and configuration objects.

You can do it by importing the component in your parent vue component
<template>
<div>
<child-component></child-component>
</div>
</template>
<script>
import ChildComponent from '#/folder/ChildComponent'
export default {
components: {
ChildComponent
},
}
</script>

Here is the approach that I follow.
Create a new file in your components folder in resources/js/components/YourComponent.vue
<template>
<div>
<h2>My awesome component</h2>
</div>
</template>
<script>
export default {
}
</script>
And in the view where you want the component, you can import it like below
<template>
<div>
<h2>Import another component</h2>
<awesome-component></awesome-component>
</div>
</template>
<script>
import awesomeComponent from "./components/YourComponent.vue";
export default {
components: {
'awesome-component': awesomeComponent
}
}
</script>

Vuejs component not registering with laravel

I know this question is being asked several times, but I couldn't find any solution to my problem.
I have two vue components on my laravel project. The first one is the laravel default component called "ExampleComponent.vue" and the second one is my own new component called "multi.vue".
I use them in a section.blade.php file like below:
#extends('layouts.app')
#section('content')
<example-component></example-component>
<multi></multi>
#endsection
but only the "example-component" works and for the "multi" component, it gives me the following error:
Unknown custom element: - did you register the component correctly? For recursive components, make sure to provide the "name" option.
here is my app.js code:
require('./bootstrap');
window.Vue = require('vue');
Vue.component('example-component', require('./components/ExampleComponent.vue').default);
Vue.component('multi', require('./components/multi.vue').default);
const app = new Vue({
el: '#app',
});
Here is my components codes:
ExampleComponent.vue:
<template>
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">Example Component</div>
<div class="card-body">
I'm an example component.
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
mounted() {
console.log('Component mounted.')
}
}
</script>
And my multi.vue:
<template>
<div>
I am multi component!
</div>
</template>
<script>
export default {
mounted() {
console.log('multi mounted.')
}
}
</script>
<style>
</style>
And the route is:
Route::get('/section',function(){
return view('section');
});
For solving this problem, all you need to do is to run "run npm watch".
After running that command, it will recomplie your vue code whenever you make a change in your code and save it.
Keep it in a separate terminal, and run "php artisan serve" in another terminal.
From https://v2.vuejs.org/v2/style-guide/#Multi-word-component-names-essential:
Component names should always be multi-word, except for root App
components, and built-in components provided by Vue, such as
<transition> or <component>.
This prevents conflicts with existing and future HTML elements, since
all HTML elements are a single word.

How to use a Laravel Nova Component in a Custom Nova Tool

I'd like to use the same loader as Laravel Nova uses when it's components are loading. I can't get it to compile. It never recognizes where to load the LoadingCard component from. Any help would be appreciated.
<template>
<div>
<heading class="mb-6">Tax Calculator</heading>
<loading-card :loading="loading" class="card relative overflow-hidden w-1/3">
<div v-if="countries.length">
<!--Make form-->
</div>
</loading-card>
</div>
</template>
<script>
import LoadingCard from 'laravel-nova'
export default {
mounted() {
let vue = this;
Nova.request().get('/nova-vendor/tax-calculator/mount')
.then(response => {
vue.countries = response.data.countries;
vue.states = response.data.states;
});
},
}
</script>
<style>
/* Scoped Styles */
</style>
Figured it out. Apparently all the Nova built-in components are available globally. Didn't realize this. All I needed to do to get it to compile was remove the import statement. I modified the code as follows:
<template>
<div>
<heading class="mb-6">Tax Calculator</heading>
<loading-card :loading="loading" class="card relative overflow-hidden w-1/3">
<!--Make form-->
</loading-card>
</div>
</template>
<script>
export default {
mounted() {
let vue = this;
Nova.request().get('/nova-vendor/tax-calculator/mount')
.then(response => {
vue.countries = response.data.countries;
vue.states = response.data.states;
});
},
}
</script>
<style>
/* Scoped Styles */
</style>
For those looking for the list of all the global laravel nova vue components, you can find here:

Where should i import the library? I tried to import it into app.js file using this code window.Lightbox = require('vue-simple-lightbox');, but then how do i use it? It seems the blade template have no idea what is 'lightbox'.
I am getting this error
[Vue warn]: Unknown custom element: - did you register the component correctly? For recursive components, make sure to provide the "name" option.
What is the correct way of importing the library and then use it inside the blade template? Thanks!
Extract your js code to a single file, blade templates are not compiled and it wont work if you import it there.
So copy everything over to say, app.js, then include it via a script tag
Inside app.js you can import lightbox from 'vue-simple-lightbox'
Now, make sure you add it to your webpack.mix file through
.js('path/to/app.js', 'public/js/app.js')
That way the library will get compiled into the asset.
Now, regarding the VUE tempalte not finding the lightbox component.
You forgot to add the component part of the Vue instance:
import Lightbox from 'vue-simple-lightbox'
export default {
components: {
Lightbox //HERE
},
...
You can import the file directly from GitHub:
<script src="https://github.com/vrajroham/vue-simple-lightbox/blob/master/dist/vue-simple-lightbox.js"></script>

Vue.js bind ajax loaded v-on click handlers

I'm taking over a project that has a lot of AJAX loaded HTML snippets. I want to progressively introduce Vue.js where I can. I'm not trying to async load any component definitions or javascript, but I would like to load an HTML snippet that has a v-on:click binding like this:
<button class="btn btn-primary" v-on:click="showModal=true">
Show Modal Dialog
</button>
Is there anyway for vuejs to parse html snippets that come down from jQuery and read the v-* attributes?
You can use <v-runtime-template> to load Vue template strings at runtime:
<template>
<div id="app">
<template v-if="template">
<v-runtime-template :template="template"></v-runtime-template>
</template>
<div v-else>Loading...</div>
</div>
</template>
<script>
export default {
data() {
return {
template: ''
}
},
mounted() {
this.template = this.getVueTemplateFromServer();
},
methods: {
getVueTemplateFromServer() { /*...*/ }
}
}
</script>

Vuejs js for multiple pages, not for a single page application

I need to build an application using laravel 5.3 and vuejs 2, because I need to use two-way binding rather than use jquery.
I need to set up the views with blade templates. Then, I need to use vuejs in each page as mentioned below.
resources/asserts/js/components/List.vue
<script>
const panel = new Vue({
el: '#list-panel',
name: 'list',
data: {
message: 'Test message'
},
methods: {
setMessage: function(){
this.message = 'New message';
}
}
})
</script>
resources/asserts/views/post/index.blade.php
<div id="panel" class="panel panel-default">
<div class="panel-heading">Posts</div>
<div class="panel-body">
<p>{{ message }}</p>
<button v-on:click="setMessage">SET</button>
</div>
</div>
There is Add.vue to create.blade.php etc...
In Add.vue el: '#add-panel'
This is my app.js. I already commented default code like follows.
Vue.component('list', require('./components/List.vue'));
Vue.component('add', require('./components/Add.vue'));
// const app = new Vue({
// el: '#app'
// });
I hardly checked most of documentations and tutorials. But they use a single js file. They use components for small elements with template, not only js.
Is it possible to use vuejs this way? Do I need to use app.js. What is the best way to do this?
If you want to sprinkle a bit of vuejs within your blade files you have basically two options:
Option #1
Declare global Vue components
Example
// in laravel built in app.js file
Vue.component('foo', require('./components/Foo.vue'));
Vue.component('bar', require('./components/Bar.vue'));
const app = new Vue({
el: '#app'
});
create a main layout file where the root div has an id of #app
// layout.blade.php
<html>
<header></header>
<body>
<div id="app">
#yield('content')
</div>
</body>
</html>
Finally in your views:
//some-view.blade.php
#extends('layout')
#section('content')
<foo :prop="{{ $someVarFromController }}"></foo>
#endsection
Option #2
This is what I am currently using, and gives me more flexibility actually
// in laravel built in app.js file
const app = new Vue({
el: '#app',
components: {
Foo: require('./components/Foo.vue'),
Bar: require('./components/Bar.vue')
}
});
In the layout file you will be using vuejs dynamic components
<html>
<header></header>
<body>
<div id="app">
#if (isset($component))
<component :is={{ $component }} inline-template>
#endif
#yield('content')
#if (isset($component))
</component>
#endif
</div>
</body>
</html>
In your views:
//some-view.blade.php
#extends('layout', ['component' => 'foo'])
#section('content')
// all the vue stuff available in blade
// don't forget to use the # symbol every time you don't want blade to parse the expression.
// Example: #{{ some.vue.propertie }}
#endsection
And finally you can create the vue components like you always would
// resources/assets/js/components/foo.vue
<script>
export default {
// the component
}
</script>
Create your 'app' for every page in seperate JS files. Good practice would be using the same name as page name to get it clear where it belongs.
Name you main div the same as the file (fileName.php + assets/js/fileName.js).
Use #fileName' as yourel`
in blade use #{{ vue expressions }} to let Blade skip this and allow VueJS handle that.
Done. Good luck!
