I am migrating a jQuery app to Vuejs2. I really like Vue but am not sure what the best way to have a modal component would be (I'm using Bootstrap4 for css and modal components). I'd like to do something like this:
addMore: function(){
alert("adding more");
var html = HandlebarsTemplates['vendors/pricings/dashboard/modals/change-pricing-model']();
$('.modal-content').html(html);
$('#myModal').modal('show')
},
and have:
<div v-on:click="addMore">add more</div>
but, to the best of my knowledge, this doesn't work. What is the standard pattern for having modals in a Vue app (preferabley using Bootstrap)?

I am able to build vue web component and load it in other pages, but I can't find document how to correctly include a UI framework. It seems the web component is under shadowDOM and import css using style tag won't work.
(Add the CDN link in the template and style is applied)
Any hint on any framework, Vuetify or Ant Design or Tailwind CSS will be appreciated.
Similar question: Vuetify build as Web component style not showing
Using custom elements without Shadow DOM is trivial. Just add like the way you do traditionally. However, with Shadow DOM, things are tricky. Only inheritable CSS styles pass through the Shadow DOM. Everything else is blocked. No straight forward integration with existing design systems (Vuetify, Ant, etc.) is not directly possible if that library is only exposing global CSS.
If the design system or a component library is exposing styles i.e. css files for individual components, then you can that with some effort.
The best solution is to use constructable stylesheet. You can use a bundler like Webpack to load the stylesheet for individual component (if and only if it is provided) as a string and feed it to the stylesheet constructor method as illustrated here.
// Read SCSS file as a raw CSS text using Webpack/Rollup/Parcel
import styleText from './my-component.scss';
const sheet = new CSSStyleSheet();sheet.replaceSync(styleText);
// Use the sheet inside the web component constructor
shadowRoot.adoptedStyleSheets = [sheet];
However, Firefox and Safari are yet to implement it.
If you need a fallback, then there are ways that are not so clean. Approach is same. Import the CSS/SCSS as a string and using the template literal, add it to the element's inner style tag.
import styleText from 'ant/button.css';
class FancyComponent extends HTMLElement {
constructor() {
super();
const shadowRoot = this.attachShadow({ mode: 'open' });
shadowRoot.innerHTML = `
<!-- Styles are scoped -->
<style>
${styleText}
</style>
<div>
<p>Hello World</p>
</div>
`;
}
}
customElements.define('fancy-comp', FacyComponent);
This all relies on the assumption that ant/material/veutify is exposing styles as individual files instead of one global file.
Alternately, the browsers have started supporting the link tag inside the Shadow DOM. But again it is really useful if you have styles for individual components. Read more about that here.
I want to use the library like Vimeo Player SDK with Nuxt.js.
<template>
<iframe
id="video01"
ref="video01"
src="https://player.vimeo.com/video/{videoID}">
</iframe>
</template>
<script>
import Player from '#vimeo/player'
export default {
created () {
const iframe = this.$refs.video01
const player = new Player(iframe)
}
}
</script>
But I cannot get DOM.
In case of SPA, I couldn't get DOM.
So error log is here.
TypeError: You must pass either a valid element or a valid id.
In case of SSR, window cannot use.
So error log is here.
window is not defined
Can't I use Vimeo Player SDK with Nuxt.js?
Did you try the vue-vimeo-player package? It could be helpful to have something managed the Vue way.
For the SPA, you will need to wait for the element to be on the page; hence try your code in a mounted hook (created step is before anything get mounted to the DOM).
If you want SSR too, you could try to wrap the whole thing into a
<client-only>
<! --- note I used vue-vimeo-player and not the vimeo-player --->
<vue-vimeo-player ref="player" :video-id="yourVideoID"/>
</client-only>
Here is a repo that I've created to show you how simple it is to make it work: https://github.com/kissu/so-nuxt-vimeo/blob/master/pages/index.vue
It made me find that you should use the <vue-vimeo-player /> component and not <vimeo-player />.
However, I imported the Vue wrapper for Vimeo Embed Player in the demo locally in a Vue component.
So I'm trying to add Vue3 to an existing asp.net core project. What I'd like to happen is for my razor app to render as normal, then use custom vue components to give my frontend a more reactive feel. However, when I mount an empty vue app to my wrapper div (parent of all other body content), it seems to be deleting all innerHTML of that wrapper div, completely removing all server rendered body content.
In my _Layout.cshtml file, I'm wrapping all content in a div with id 'app'.
<body>
<div id='app'>
#RenderBody()
</div>
<script src="~/js/vue-app/dist/js/chunk-vendors.76316534.js"></script>
<script src="~/js/vue-app/dist/js/app.bf4c5ba9.js"></script>
</body>
in main.js
import { createApp } from 'vue'
const vueApp = createApp({}).mount('#app');
// component definitions below
With the app set up like this, when I run my .net project I see a blank white browser window instead of the razor compiled html that I expect. In Vue2, it was possible to do this:
const vueApp = new Vue({
el: '#app',
data: {
....
},
methods: {
....
}//, etc
});
Which would result in the app being rendered as normalthe vue app bound to #app, making vue available to the child content (model binding, vue click handling, etc).
I've tried playing around with the isHydrate optional parameter on mount(), but it causes no change in the result.
Am I missing something here? How do you slowly migrate an existing project to use vue3 if you can't mount the app without clearing content? Any guidance is much appreciated.
Thank you
Notes:
vue-next runtime-dom source If this method is the mount method getting called, I'm not sure why container.innerHTML would not be getting set in the component. {} is not a function, and render/template is not defined for it.
vue-next runtime-core apiCreateApp source If this is the method getting called....I have no idea.
Update
Vue 3, without template renderer, will not be able to handle the templates after it has been compiled. To fix that, you can import vue/dist/vue.esm-browser (and vue.runtime.esm-browser.prod for prod), instead of the default vue. This will allow run-time component rendering.
I am working on a Vue.js application that I am almost done, one major bug left. The bug/issue is that when you go to /login and login to the site you get redirected via a router push (tried replace too) and when this happens I want to render the whole dashboard. Currently since in my App.vue file the router view is a different part it only renders the dashboard info part and not my header or sidebar.
Pretty much imagine a dashboard without a header or sidebar. That's what's rendering. I'd be okay if I could do something like F5 does because then it all would load correctly though taking up to 2 seconds longer on login which is okay by me.
My App.vue file template code
<template>
<div class="fade page-sidebar-fixed page-header-fixed show page-container" v-if="!pageOptions.pageEmpty" v-bind:class="{
'page-sidebar-minified': pageOptions.pageSidebarMinified,
'page-content-full-height': pageOptions.pageContentFullHeight,
'page-with-top-menu': pageOptions.pageWithTopMenu,
'page-sidebar-toggled': pageOptions.pageMobileSidebarToggled,
'has-scroll': pageOptions.pageBodyScrollTop
}">
<Header />
<Sidebar v-if="!pageOptions.pageWithoutSidebar" />
<div id="content" class="content" v-bind:class="{ 'content-full-width': pageOptions.pageContentFullWidth, 'content-inverse-mode': pageOptions.pageContentInverseMode }">
<router-view></router-view>
</div>
</div>
<div v-else>
<router-view></router-view>
</div>
</template>
Looks like I have resolved my issue, it comes from vue-router and how I am doing that if statement in my template code. So in that code I am checking a boolean value then choosing which view to render. So I had though on all of my auth pages I set the value correctly on exit. Turns out not...
This was in my Login.vue file, idea was to have on an exit of the route that it would change the boolean to false which would let me render it right. This was something I did initally but had forgotten about till about 20 minutes ago.
Upon checking this I found the value was not being changed for some reason. So as a work around in the created part of my Dashboard.vue file I set the value to false explicitly
Login.vue
beforeRouteLeave (to, from, next) {
PageOptions.pageEmpty = false;
next();
},
Dashboard.vue
created() {
PageOptions.pageEmpty = false;
...
}
The main idea is to have several base pages each one of them is operate with its own set of internal views.
You have to redirect user to another view, which is the one and only active view and this view can contains sidebar header and main part that also contains router-view, and then! you load any needed components in it.
You have to have something like that:
App component is only contains router view tag and any other pages are load into this.
The routes structure then looks like that:
As you can see, there are two base views load in App view. And then the base view can has a lot of children. The level of nested routes is up to you. Here is the contents of my app Home view:
And the MainContent component which is contains router view only:
The good example of project structure is the one generated with vue-cli. You can use it to simplify dev process with a lot of benefits and good practice solutions.
Think about a wordpress blog, or a standard CMS with some content. I use a wysiwyg editor (CKEditor) to write my contents and save them to db.
I want to use some Vue components inside this HTML, and so I add a wrapper div to my theme. HTML pages are wrapped by
<div id="#my-custom-app">
...html from server
</div>
Basically I want to add for example
<my-app-image-compare></my-app-image-compare>
using CKEditor inside my HTML, then I will create an app mounted on #my-custom-app div. I will insert the app at the end of the html body.
Vue.app file doesn't have a template, the template is basically my HTML page written with CKEditor, but every component is loaded and defined by the app and every component has a template.
How can I do? Is there a way to have a main Vue app file without a defined template?
Option 1:
First create a vue container on a basic template. This template will then load a component which gets your data from the sever and displays it, so:
// This is your main vue instance container
<div id="#my-custom-app">
<dynamic-html v-if="myHtmlFromServer" template="myHtmlFromServer"></dynamic-html>
</div>
Within this main component, you need to hook up created event and populate myHtmlFromServer with your HTML content from the editor.
import DynamicHtml from './myComponents/DynamicHtml'
new Vue({
el: '#my-custom-app',
data () {
return {
myHtmlFromServer: ''
}
},
components: {
DynamicHtml
}
created () {
// this.myHtmlFromServer = this.getDataFromServer()
}
})
The <dynamic-html> component, would have props: ['template'] and on the created event would assign this.$options.template = this.template.
This option will set the HTML template of that component and allow Vue to render it as normal (meaning you can then do {{someVal}} in your CKEditor.
Option 2:
Another option is if you're using a server side language like PHP, then you could just put that html on the page i.e echo $myHtmlContent and as long as that content contains <div id="#my-custom-app"> you Vue instance will mount. PHP will add the HTML to the page before the JS processes the page so it'll just work.
