What is Vue.js?

VueJS is an open source progressive JavaScript framework for developing an interactive web interface. It is one of the most popular web development frameworks. Vue focuses on the view layer. It is easy to integrate into big projects requiring front-end development without any issues.It is very simple to install VueJS. In a matter of minutes, any developer can build interactive web interfaces.

Directives

In Vue.js, uses double braces {{ }} for data placeholders.Vue.js directives are HTML attributes beginning with v-

Vue Example

The following example creates a new Vue object with new Vue().In this case, el: binds the new Vue object to the HTML element with id=”app”.
Example:

<div id="app">
<h1>{{ message }}</h1>
</div>

<script>
var myObject = new Vue({
el: '#app',
data: {message: 'Hello Vue!'}
})
</script>

Binding

Binding a Vue object to an HTML element results in the HTML element changing when the Vue object changes:
Example:

<div id="app">
{{ message }}
</div>

<script>
var myObject = new Vue({
el: '#app',
data: {message: 'Hello Vue!'}
})

function myFunction() {
myObject.message = "John Doe";
}
</script>

Two-Way Binding

The v-model directive binds the value of HTML elements to application data.This is called two-way binding:
Example:

<div id="app">
  <p>{{ message }}</p>
  <p><input v-model="message"></p>
</div>

<script>
var myObject = new Vue({
el: '#app',
data: {message: 'Hello Vue Developers!'}
})
</script>

Loop Binding

The following example shows how you can use the v-for directive to bind an array of Vue objects to an array of HTML elements:
Example:

<div id="app">
 <ul>
   <li v-for="x in todos">
   {{ x.text }}
   </li>
  </ul>
</div>

<script>
myObject = new Vue({
el: '#app',
data: {
    todos: [
     { text: 'Learn JavaScript' },
     { text: 'Learn Vue.js' },
     ]
    }
})
