I'm new to vue.js so I know this is a repeated issue but cannot sort this out.
the project works but I cannot add a new component. Nutrition component works, profile does not
My main.js
import Nutrition from './components/nutrition/Nutrition.vue'
import Profile from './components/profile/Profile.vue'
var Vue = require('vue');
var NProgress = require('nprogress');
var _ = require('lodash');
// Plugins
Vue.use(require('vuedraggable'));
// Components
Vue.component('nutrition', Nutrition);
Vue.component('profile', Profile);
// Partials
Vue.partial('payment-fields', require('./components/forms/PaymentFields.html'));
// Filters
Vue.filter('round', function(value, places) {
return _.round(value, places);
});
Vue.filter('format', require('./filters/format.js'))
// Transitions
Vue.transition('slide', {enterClass: 'slideInDown', leaveClass: 'slideOutUp', type: 'animation'})
// Send csrf token
Vue.http.options.headers['X-CSRF-TOKEN'] = Laravel.csrfToken;
// Main Vue instance
new Vue({
el: '#app',
components: {
},
events: {
progress(progress) {
if (progress === 'start') {
NProgress.start();
} else if (progress === 'done') {
NProgress.done();
} else {
NProgress.set(progress);
}
},
'flash.success': function (message) {
this.$refs.flash.showMessage(message, 'success');
},
'flash.error': function (message) {
this.$refs.flash.showMessage(message, 'error');
}
}
});
Profile.vue
<template>
<div class="reddit-list">
<h3>Profile </h3>
<ul>
</ul>
</div>
</template>
<script type="text/babel">
export default {
name: 'profile', // this is what the Warning is talking about.
components: {
},
props: {
model: Array,
}
}
</script>
profile.blade.php
#extends('layouts.app')
#section('title', 'Profile')
#section('body-class', 'profile show')
#section('content')
<script>
window.Laravel.profileData = []
</script>
<profile></profile>
#endsection
Whenever I try to go to this page I get:
[Vue warn]: Unknown custom element: <profile> - did you register the component correctly? For recursive components, make sure to provide the "name" option.
I tried doing a local component such as
Vue.components('profile', {
template: '<div>A custom component!</div>'
});
or even I tried adding the profile into the components in vue but still no luck, can anyone point me in the right direction?
Simply clear the cache on your browser if you run into this problem. Worked pretty well for me
I didn't fixed it but it was fixed by itself it appears some kind of magic called (CACHE). i did have my gulp watch running but i powered off my computer, and then ON again and it works.

I am now using the newest version of Alpine which is v3.
Making reusable components needs to be registered using the Alpine.data.
This is the alpinejs.js
import Alpine from 'alpinejs'
import form from './components/form'
window.Alpine = Alpine
Alpine.data('form', form)
Alpine.start()
This is what I have in the components/form.js
export default (config) => {
return {
open: false,
init() {
console.log(config)
},
get isOpen() { return this.open },
close() { this.open = false },
open() { this.open = true },
}
}
This is the html part:
<div x-data="form({test:'test'})"></div>
This is the error I get in the console:
Any idea how to pass parameters to Alpine.data?
I stumbled over this question, searching for an answer but figured it out now. Maybe its still usefull to someone...
You have do define the parameter when registering the data component:
document.addEventListener('alpine:init', () => {
window.Alpine.data('myThing', (param) => MyModule(param));
});
Now you can use it in your module on init...
export default (param) => ({
init() {
console.log(param);
}
});
... when you init the component
<div x-data="deliveryDate({ foo: 'bar' })"></div>
This likely happens since you imported your script as a module. Therefore, you need another script that handles initialization of data.
I'm using a vanillajs vite setup and here's a working implementation with alpinejs:
index.html
<head>
<!-- Notice the type="module" part -->
<script type="module" src="/main.js" defer></script>
<script src="/initializer.js"></script>
</head>
<body x-data="greetingState">
<button #click="changeText">
<span x-text="message"></span>
</button>
<h2 x-text="globalNumber"></h2>
</body>
main.js
import Alpine from 'alpinejs';
window.Alpine = Alpine;
Alpine.start();
// const globalNumber = 10; // Wrong place
initialize.js
document.addEventListener('alpine:init', () => {
Alpine.data('greetingState', () => ({
message: "Hello World!",
changeText() {
this.message = "Hello AlpineJs!";
},
}));
});
const globalNumber = 10; // Correct place
Note that listening to the alpine:init custom event inside of a javascript module will break the app. The same happens if you try to display a variable from a script of type module, in this example globalNumber.
I am using Laravel 7 and Vue.js 2.
I want to pass an object of validation errors from the catch block of an axios call to a parent component but for some reasons it doesn't work.
This is the code of the axios call:
runReport: function() {
let self = this;
const url = "api/get_report?room="+this.formReport['room']+"&participant="+this.formReport['participant']+"&start="+this.formReport['start']+"&end="+this.formReport['end'];
axios.get(url)
.then((response) => {
console.log(response.data.data);
this.meetingsReport = response.data.data;
this.$emit('passMeetings', this.meetingsReport);
this.$emit('success');
this.errors = {};
})
.catch(function(error) {
console.log(error.response.data);
self.errors = error.response.data;
alert(self.errors);
self.$emit('failure');
self.$emit('passErrors', self.errors); //problem
console.log('call ended');
});
}
This is the code in the parent component:
<template>
<div>
<report-meeting #passMeetings="onPassMeetings" #failure="displayTable=false" #success="displayTable=true"></report-meeting>
<hr>
<validated-errors :errorsMeeting="errorsMeeting" #passErrors="onPassErrors" v-if="displayTable===false"></validated-errors>
<table-report :meetingsSelected="meetingsSelected" v-if="displayTable===true"></table-report>
</div>
</template>
<script>
import TableReport from "./TableReport.vue"
import ReportMeeting from "./ReportMeeting.vue"
import ValidatedErrors from "./ValidatedErrors.vue"
export default {
components: {
'table-report': TableReport,
'report-meeting': ReportMeeting,
'validated-errors': ValidatedErrors
},
mounted() {
console.log('Component mounted.');
},
data: function() {
return {
displayTable: false,
meetingsSelected: {},
errorsMeeting: {}
}
},
methods: {
onPassMeetings(value) {
console.log(value);
this.meetingsSelected = value;
},
onPassErrors(value) {
console.log('errors passed'); //never used
this.errorsMeeting = value;
}
}
}
</script>
In the console I visualize no errors (except an 422 Unprocessable Entity). The strange thing is that the first emit works (failure), but the second one doesn't work (passErrors).
In the parent function onPassErrors I put a console.log that is never used so I suppose that the function is never called.
Can help?
This is likely caused by an event name mismatch, which can occur when using in-DOM templates because HTML attributes are automatically lower-cased (#passErrors becomes #passerrors in the DOM).
When using the development build of Vue, you'd see a warning in the browser's console:
[Vue tip]: Event "passerrors" is emitted in component but the handler is registered for "passErrors". Note that HTML attributes are case-insensitive and you cannot use v-on to listen to camelCase events when using in-DOM templates. You should probably use "pass-errors" instead of "passErrors".
This is not a problem in single file components (demo 1) or string templates (demo 2), but if you must stick with in-DOM templates, custom event names are recommended to be kebab-case:
<!-- Parent.vue -->
<MyComponent #pass-errors="onPassEvent" />
// MyComponent.vue
runReport() {
this.$emit('pass-errors', /*...*/)
}

I want create global method to translate message using Laravel-JS-Localization
But when i call the method using vue mustache got an error like this:
Property or method "trans" is not defined on the instance but referenced during render.
Make sure that this property is reactive.
Here my laravel app.js code:
require('./bootstrap');
window.Vue = require('vue');
Vue.component('dashboard', require('./components/Dashboard').default);
const app = new Vue({
el: '#vue',
methods: {
trans: function (key) {
return Lang.get(key);
},
},
});
Dashboard.vue code :
<template>
<p>{{ trans('common.welcome') }}</p>
</template>
<script>
data () {
return {
name: '',
}
},
</script>
dashboard.blade.php code :
..........
<div class="col-9" id="vue">
<dashboard></dashboard>
</div> <!--c end col-8 -->
..........
I would probably go with creating a Plugin. For example
Vue.use({
install (Vue) {
Vue.prototype.$trans = Lang.get
}
})
Adding this to your app.js code before creating any components or new Vue({...}) will mean all your components will have access to the $trans method.
Alternatively, you can create a Global Mixin but these aren't strongly recommended.
Use global mixins sparsely and carefully, because it affects every single Vue instance created, including third party components
Vue.mixin({
methods: {
trans (key) {
return Lang.get(key)
}
}
})
I have const:
export const globalUser = new Vue({
created: function(){
this.getActualUser();
},
data: {
ActualUser: {name:'',meta:'',tipo:''}
},
methods:{
getActualUser: function(){
var urlMeta='usuarioActual';
axios.get(urlMeta).then(response=>{
this.ActualUser=response.data;
});
}
}
});
Now i'm importing that in a component of vue js
import {globalUser} from '../app.js'
Here is my data:
data:function(){
return {
usuarioActual:globalUser.ActualUser,
anotherData:{}
}
}
This returns me:
"usuarioActual": {
"name": "",
"meta": "",
"tipo": ""
}, the data is empty.
What i want is the returns me data after the method getActualUser run:
ActualUser: {name:'currentName',meta:'currentDat',tipo:'currentType'}
It works well:
axios.get(urlMeta).then(response=>{
this.ActualUser=response.data;
});
I did it in a wrong way, maybe it will work.
I get a different solution:
Instead of using data in components, i'm using "props".
I don't need to import, just called the props in the blade template of laravel, there i can use #elements from laravel.
Props in component:
props:{
usuario:String
},
Now i'm using that:
#extends('layouts.app')
#section('content')
<user-component usuario="{{ Auth::user()->name }}"></user-component>
#endsection
Works well, if you need more data u can add a function in the Model.
Now i can use that in my template of component
<template>
<tr v-if="{{usuario}} =='Admin'">
My code is to realize a paginate page like this example, https://github.com/bitovi/canjs/blob/master/component/examples/paginate.html .
I found the {#messages}...{/messages} in message.mustache template was not been inserted into page , while messagelist component inserted event has been triggered, so i can not do any binding to {#messages} dom in the event, because it ‘not exists in the page.
Are there other ways to fix this problem?
The Templates:
message_list.mustache:
<app>
<messagelist deferredData='messagesDeferred'></messagelist>
<next-prev paginate='paginate'></next-prev>
<page-count page='paginate.page' count='paginate.pageCount'></page-count>
</app>
message.mustache:
{#messages}}
<dl>
<dt>.....</dt>
<dd>....</dd>
</dl>
{/messages}
The Component:
can.Component.extend({
tag: "messagelist",
template: can.view('/static/web/tpl/mobile/message.mustache'), // to load message template
scope: {
messages: [],
waiting: true,
},
events: {
init: function () {
this.update();
},
"{scope} deferreddata": "update",
update: function () {
var deferred = this.scope.attr('deferreddata'),
scope = this.scope,
el = this.element;
if (can.isDeferred(deferred)) {
this.scope.attr("waiting", true);
deferred.then(function (messages) {
scope.attr('messages').replace(messages);
});
} else {
scope.attr('messages').attr(deferred, true);
}
},
"{messages} change": function () {
this.scope.attr("waiting", false);
},
inserted: function(){
// can't operate the dom in message.mustache template
}
}
});
//to load component template
can.view("/static/web/tpl/mobile/message_list.mustache",{}, function(content){
$("#message-list").html(content)
});
I have solved the problem, but not the best, Maybe someone have a better way.
I changed my template, add a new component called <messageitem>
<messageitem> will load another template: message.mustache
Every <messageitem> will trigger inserted event when inserted into <messagelist>
The new component:
can.Component.extend({
tag: "messageitem",
template:can.view('/static/web/tpl/mobile/message.mustache'),
events: {
inserted: function(el, ev){
// Can-click can not satisfy my needs,
// because i call the third-party module to bind click event
// this module will be called repeatedly, not the best way
reloadModules(['accordion']);
}
}
});
// To load message_list.mustache
can.view("/static/web/tpl/mobile/message_list.mustache",{}, function(content){
$("#message-list").html(content)});
Static html:
<body>
<div id="message-list">
....
</div>
</body>
message_list.mustache:
<app>
<messagelist deferredData='messagesDeferred'>
{{#messages}}
<messageitem></messageitem>
{{/messages}}
</messagelist>
<next-prev paginate='paginate'></next-prev>
<page-count page='paginate.page' count='paginate.pageCount'></page-count>
</app>
message.mustache:
<dl class="am-accordion-item" >
...
</dl>
