I am pretty new to Vue.js.
I am trying to build a project without cli.
I've tried to add the CDN into the index.html.
and create a app.js file , add it to index.html and it works well.
Then I watch some youtube and tutorial, the idea of component kicks in and I am trying to add the Single-File Components into the project.
But I do not know how to structure the files so that it could work with the components.
Here are what I've got so far , could someone please tell me what's wrong here？
Any suggestions would be appreciated.
Many Thanks.
Oren

SFCs require a build step and is recomended
When using standard Vue without a build step and mounting to in-DOM templates, it is much less optimal because:
We have to ship the Vue template compiler to the browser (13kb extra size)
The compiler will have to retrieve the template string from already instantiated DOM
The compiler then compiles the string into a JavaScript render function
Vue then replaces existing DOM templates with new DOM generated from the render function.
If you still don't want a build step, take a look at petite-vue

I'm trying to get a basic VueJS application working using the code
<!DOCTYPE html>
<html>
<head>
<script src="https://unpkg.com/vue#3"></script>
<link rel="icon" href="/favicon.ico" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
</head>
<body>
<div id="app"></div>
<script type="module">
import { createApp } from 'vue'
import MyComponent from './my-component.js'
createApp(MyComponent).mount('#app')
</script>
</body>
</html>
But all I see is the error of 'Error resolving module specifier “vue”. Relative module specifiers must start with “./”, “../” or “/”.' when I browse to localhost:3000 on Firefox. I've been at this for hours but I can't figure out why it doesn't work when I've copied it from the VueJS page 'getting started'. I've used the commands 'npm run dev', 'npx serve' and 'npm run build' but they all return the same error in the web developer tools' console.
Any help or guidance on this would be appreciated.
It seems that you are using the global build of Vue where all APIs are exposed under the global Vue variable (line 4 in your example).
Solution 1
Remove the import line for vue and prepend createApp with "Vue.":
//REMOVED: import { createApp } from 'vue'
import MyComponent from './my-component.js'
Vue.createApp(MyComponent).mount('#app') //NOTE that "Vue." has been added
Solution 2
Another solution would be to add an importmap block. That way, you can refer to vue as specified in the importmap and the corresponding url is resolved from there. Unfortunately, this is (at the moment) only supported by Chromium-based browsers. Luckily, a shim is available to allow use of importmap on non-Chromium browsers.
See below for an example, where the shim is injected above the importmap-block. Note that the script-line for loading vue has been removed from the header-block.

I'm trying to decrease the bundle size of my Vue project, which scaffolded by the vue-cli, by using CDN of firebase, Vue, and Vuetify.
So, I've added links of these CDN in public/index.html as follow:
<!DOCTYPE html>

Add config.externals to vue.config.js as follow:
module.exports = {
"transpileDependencies": [
"vuetify"
],
chainWebpack: (config) => {
config.externals({
firebase: 'firebase',
'firebase/auth': 'firebase',
firebaseui: 'firebaseui',
vue: 'Vue',
vuetify: 'Vuetify',
'vuetify/lib': 'Vuetify',
})
}
}
Then, the report.html created by issueing yarn build --report indicated that the Vuetify is still in the bundle even other firebase and Vue is going away as follow:
Is there any wrong or insufficient steps?
If you are using vuetify from vue-cli-plugin-vuetify (vue add vuetify), treeshaking and auto component import is enabled by default, by using vuetify-loader.
If you look into the source code of vue-cli-plugin-vuetify, it only uses vuetify-loader if it is present in your package.json. So removing vuetify-loader from package.json should disable this behavior.
https://alligator.io/vuejs/stripe-elements-vue-integration/
On this website, it says we need to import the file with the script tag in the index.html file, which I did, but I noticed I get a js error.
It's only when I imported directly the script inside the component that the error "'Stripe' is not defined" disappeared.
<template>
<div>
</div>
</template>
<script src="https://js.stripe.com/v3/"></script>
<script>
export default {
name: 'component',
}
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
</style>
I don't want to import it directly inside my component, because it's not clean, what can I do?
<!DOCTYPE html>

<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<script src="https://js.stripe.com/v3/"></script>

Late to the party, but here is a solution that works for me
Your index.html file looks fine:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<script src="https://js.stripe.com/v3/"></script>
<title>vue-app</title>
</head>
<body>
<div id="app"></div>
<!-- built files will be auto injected -->
</body>
</html>
Then in the component where you want to use it, you can access stripe with the window object, and set the publishable key. This can be done locally in a method, or globally for the component, like this:
<script>
const stripe = window.Stripe(process.env.VUE_APP_STRIPE_PK)
export default {
data() {
return {
// ...
}
},
methods: {
async confirmPayment() {
const paymentResult = await stripe.confirmCardPayment(this.clientSecret, {
receipt_email: 'email#example.com',
})
console.log('paymentResult:', paymentResult)
},
},
}
</script>
I think you should move the script tag of Stripe before the rest of your JavaScript code. The code is probably trying to access the Stripe object before it's been loaded.
hi I'm trying to autocomplete/typeahead component for Vue 2 and Bootstrap 4
This is my code.
<html>

<script src="https://unpkg.com/vue-bootstrap-typeahead"></script>
<script>
import VueBootstrapTypeahead from 'vue-bootstrap-typeahead';
Vue.component('vue-bootstrap-typeahead', VueBootstrapTypeahead);
new Vue({
el: '#container',
data: {
value: '',
},
});
</script>
</body>
</html>
Unfortunately this is not working due to following errors.
SyntaxError: import declarations may only appear at top level of a module
Source map error: request failed with status 404 Resource URL:
https://unpkg.com/vue-bootstrap-typeahead Source Map URL:
VueBootstrapTypeahead.umd.min.js.map
It would be great if someone can help me on this.
The code <script src="https://unpkg.com/vue-bootstrap-typeahead"></script> has imported the VueBootstrapTypeahead, and became a property of window.You don't need import again. when we talk about import, often the module concert come to us too. import declarations was often used in an app which need be transformed by tools, such as babel,webpack or rollup.
Please add this to the <head> of your document before the <link> tags:

Sketchup uses html for its extension user interface.
I'm trying to make an interface with vue.js + vuetify.
Sketchup can render the page but I can't send data to javascript.
Sketchup sends data to javascript by calling a function and passing data.
Vue.js invokes an action callback when it's mounted.
Sketchup then executes the function updateUI(data). At this moment the interface throws an error: Uncaught ReferenceError: updateUI is not defined
at index.html:1
This is my main.js file where Vue is initialized and the updateUI function is declared.
import Vue from 'vue'
import './plugins/vuetify'
import App from './App.vue'
import shared_data from './stores/shared_data';
function updateUI(data){
shared_data.data.parameters = data.parameters;
}
Vue.config.productionTip = false
var gui = new Vue({
render: h => h(App),
}).$mount('#app')

Try to add the function you want to call to the Window object, making sure it remains a global function and doesn't get wrapped inside an anonymous module when you build your JS.
window.updateUI = function(data){
shared_data.data.parameters = data.parameters;
}
You can also example a complete set of example in this github repo: https://github.com/SketchUp/htmldialog-examples (Example 4 introduces Vue.)
