Vue.js a JavaScript framework for robust web applications

CDN:

---

As per our recommendation download VueJs development version file from Download and simply include or use CDN link in your webpage:

For production version of your published site, replace vue.js with vue.min.js for faster loading and speed optimization compare to development environment. It is smaller build for optimized speed experience.

The Vue Instance:

---

Every VueJs application starts with the new Vue instance. We can create Vue instance using Vue function:

Here Vue instance assign to vm variable. Now we can often use vm to access Vue instance in application.

VueJS

Output: Hello Vue!

For Vue there is one parameter named el. The value of this parameter will be id of div which is defined in body tag of your file.

Data & Methods

---

Any application instance is to render data or view as per their requirement. In the above example, you can see the message variable is a part of the data attribute of vue instance. Now we check method with the following example:

VueJS

{{a}}

Output: 4

As above example gives you 4 as output. Here you can check that methodsquare() method is called by instance vm and it will update the value of a variable to 4 which is the square of 2. You can define method in VueJs in methods attribute.

Here created hook is executed after Vue instance is created. There is more Vue life cycle hooks named mounted, update and destroy.

Life Cycle of VueJs is as follow:

Data Binding

---

Data Binding is another interesting topic when we are working on an advanced JavaScript framework like Vue. In Vue, we can use v-model for two-way data binding on form inputs and other elements like text area.

v-modal has correctively updated the element based on the entered value in inputs like textbox or text area.

Vue Js

Here msg string update at a same time when you will have typed in input box. it is two-way data binding.

We can bind Class and CSS using v-bind: class in VueJs. Let we check it with example:

Events

---

Vue.js use v-on directive for performing DOM element event based on event fired run some JavaScript code to achieve objective to perform this event. Let me explain it by the small example of a button click will increases counter.

Example:

Event Modifier

---

We are familiar with JavaScript event.preventDefault() or event.stopPropagation() event modifier. We need to write this code inside the function when we are using basic JavaScript but in VueJs the thing differs, Vue.js approach is that the logic code only placed in function so for addressing this issue Vue use dot.
