capture
It should be <div id="app"> not <div id="#app"> and the script that includes the vue instance should be at the end of body element :
<!DOCTYPE html>

My Vue and index.js are not working together

Why is my Vue and index.js import not working?
In my live server the text just shows up as {{ message }}
the html and js files are located in the same directory
var app = new Vue({
el: '#app',
data: {
message: 'Hello Vue!'
}
})

Your data must be a function.
new Vue({
el: '#app',
data()
return {
title: 'Hello world!',
};
}
});
See docs: https://v2.vuejs.org/v2/guide/components.html#data-Must-Be-a-Function
You're using a CDN link that uses Vue 3 version with a code syntax that runs in Vue 2, since you're beginner you should change the CDN link to vue 2 :
<script src="https://cdn.jsdelivr.net/npm/vue#2.6.11"></script>
let app = new Vue({
el: '#app',
data: {
title: 'Hello world!'
}
});
<script src="https://cdn.jsdelivr.net/npm/vue#2.6.12"></script>
<div id="app">
<p>{{ title }}</p>

Vue.js - axios is undefined when trying to store and display vue-axios response data

I cannot seem to able to get vue-axios to fetch, store and display data in browser. I tried this and getting undefined when getData button is clicked.
new Vue({
el: '#app',
data: {
dataReceived: '',
},
methods: {
getData() {
axios.get('https://min-api.cryptocompare.com/data/price?fsym=BTC&tsyms=USD')
.then(function(response) {
this.dataReceived = this.response;
console.log(this.dataReceived);
return this.dataReceived;
})
}
}
})

I would add to #boussadjrabrahim's excellent answer that you need to use a fat arrow notation inside your then callback to make sure that the this keyword is bound to your Vue instance. Otherwise your dataReceived will remain blank.
new Vue({
el: '#app',
data: {
dataReceived: '',
},
methods: {
getData() {
axios.get('https://min-api.cryptocompare.com/data/price?fsym=BTC&tsyms=USD')
.then((response) => {
this.dataReceived = response.data;
console.log(this.dataReceived);
return this.dataReceived;
})
}
}
})

You're missing axios library so add it as follow :
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
Another thing to rectify is this.response change it to response.data
new Vue({
el: '#app',
data: {
dataReceived: '',
},
methods: {
getData() {
axios.get('https://min-api.cryptocompare.com/data/price?fsym=BTC&tsyms=USD')
.then((response)=> {
this.dataReceived = response.data;
console.log(this.dataReceived);
return this.dataReceived;
})
}
}
})

Add new tags to vue-select

In the vue-select vuejs component, if you see on their demo page, you can select multiple items from the dropdown. However, if you type something that is not available in the dropdown, then you can just type that new text and press enter and it will become a tag. You can see this behavior here on their demo page:
https://sagalbot.github.io/vue-select/
However, I am unable to do this. I am able to select from the drop down, but if I type something new, then that doesn't become a tag. I have this jsbin showing what I've done. Any help is appreciated.
http://jsbin.com/xoxohenoli/edit?html,js,output
My Javascript:
Vue.component('v-select', VueSelect.VueSelect);
new Vue({
el: '#app',
data: function() {
return {
options: ["A","B"],
placeholder: 'Choose a country..',
}
},
});

You need to add taggable attribute to the component please check in working example.
please use full page for snippet to avoid overlapping console output.
