After doing some small apps in angular2 and reactjs, it's my first try with Aurelia.
I have an error in my first app following the Quick Start and just updating the app to show a "hello world":
http://aurelia.io/hub.html#/doc/article/aurelia/framework/latest/quick-start/1
I've got an error:
Uncaught (in promise) Error: No view model found in module "src/app".
at aurelia-core.min.js:7
any idea what is happing? the error is not clear for me; aurelia manage well the error messages?
"View model" means html template file?
/index.html
<!DOCTYPE html>
<html>
<head>
<title>Aurelia</title>
</head>
<body aurelia-app="src/main">
<script src="scripts/system.js"></script>
<script src="scripts/config-typescript.js"></script>
<script src="scripts/aurelia-core.min.js"></script>
<script>
System.import('aurelia-bootstrapper');
</script>
</body>
</html>
/src/main.ts
import {Aurelia} from 'aurelia-framework';
export function configure(aurelia: Aurelia) {
aurelia.use.basicConfiguration();
aurelia.start().then(() => aurelia.setRoot());
}
UPDATED: the error was app.ts was app.ts was empty !
/src/app.ts
export class App {
heading = "Hello World";
}
/src/app.html
<template>
<h1>${heading}</h1>
</template>
The error was my app.ts was empty , it's produced "No view model found"
On the index.html we bootstrap the app trough main.js or main.ts file (if we are using typescript)
/src/index.html
<!DOCTYPE html>
<html>
<head>
<title>Aurelia</title>
</head>
<body aurelia-app="src/main"> <!-- Bootstrap here -->
<script src="scripts/system.js"></script>
<script src="scripts/config-typescript.js"></script>
<script src="scripts/aurelia-core.min.js"></script>
<script>
System.import('aurelia-bootstrapper');
</script>
</body>
</html>
Aurelia have a convention. It tries to find app.js or app.ts and load it as the root module.
/src/app.ts
export class App {
heading = "Hello World";
}

I am trying to get a vue component to work from a separate file called AppButton.js. This simple learning component should render a button with some css and disables the click when one hovers over the button. Instead, this code just displays text. I cannot figure out what is missing in my code and I would appreciate if someone can take a look.
Here is the content from AppButton.js:
export default {
template: '<button class="bg-gray-200 hover:bg-gray-400 border rounded px-5 py-2 disabled:cursor-not-allowed" v-bind:disabled="processing"><slot /></button>',
data() {
return {
processing: true
}
}
}
The AppButton.js is in the same directory as my index.html. Here is the content of the index.html.
<!DOCTYPE html>

<body class="h-full grid place-items-center">

</div>

}
};
Vue.createApp(app).mount('#app');
</script>

I tried loading vue.js devtools extension in my Chrome to debug this problem further but for some reason the vue.js devtools extension does not show in my devtools
This is the error I am getting in Chrome Console: Access to script at

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.

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>
<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>
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>
<head>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet">
<link href="https://unpkg.com/vue-bootstrap-typeahead/dist/VueBootstrapTypeahead.css" rel="stylesheet">
</head>
<body>
<div id="container">
<vue-bootstrap-typeahead
v-model="query"
:data="['Canada', 'USA', 'Mexico']" />
</div>
<script

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/0.11.10/vue.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"></script>
<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:

what seems to be wrong here i dont get any error but at the same time no progress in routing. .

templateUrl : 'index.html'

});
when i load '/' in my browser nothins is happening same with /home i dont know where did i get wrong since there is no error in my console
The template for a route should be a partial view. Here index.html is the root of the single page app , this page should never reload (unless you want to destroy and rebootstrap the app). Try changing the templateUrl for / to a file that just has <h2> HELLO WORLD!</h2> and monitor the console (dev tools) for any 404 errors related to fetching the template
I think problem is with your javascript file name. In index you mentioned mainpage.js and in description its homepage.js.
Edit : Okay. Then try arranging files list like
<script type="text/javascript" src="/myAngularApp/css/angular/angular.min.js"></script>
<script type="text/javascript" src="/myAngularApp/css/angular/angular-animate.min.js"></script>
<script type="text/javascript" src="/myAngularApp/css/angular/angular-resource.min.js"></script>
<script type="text/javascript" src="/myAngularApp/css/angular/angular-route.min.js"></script>
<script type="text/javascript" src="/myAngularApp/css/bootstrap/ui-bootstrap-tpls-2.2.0.min.js"></script>
<script src="/myAngularApp/css/mainpage.js"></script>
As mentioned in the answer by user Priyanka, the filename can be the issue. But that should produce an error on the console and according to you there was no error on the console.
The other possible reason can be the sequence in which you've imported your files. I generally sequence my files this way -
<head>
<!-- 1. External CSS Libraries likes bootstrap, jquery -->
<!-- 2. My Application specific CSS files -->
<!-- 3. External JS libraries like Angular, bootstrap, JQuery -->
<!-- 4. My Application specific JS files like my controllers, services, directives etc.
</head>
Again the sequence in which you import the external JS libraries may also cause problems.
