Vue.js Tutorial

Vue.js is a progressive JavaScript framework for building user interfaces. It stands out for its simplicity, seamless integration with other libraries, and reactive data binding.

• Built on JavaScript for flexible and component-based development.
• Supports declarative rendering, reactivity, and two-way data binding.
• Provides a lightweight framework with powerful features for single-page applications (SPAs).
• Easy integration into existing projects or libraries.

To start with Vue.js, you need to install or set it up on your machine. Follow these articles to install depending on your system:

• Vue.js Introduction & Installation
• Getting Started with VueJS

Let us now take a look at our first code example.

// App.vue

<template>
    <div>
        <h1>{{ message }}</h1>
    </div>
</template>

<script>
    export default {
        data() {
            return {
                message: 'Welcome to the Vue.js Tutorial'
            };
        }
    };
</script>

<style>
    h1 {
        color: #42b983;
        text-align: center;
    }
</style>

It will start a server, and when you visit http://localhost:8080, it will display

Welcome to the Vue.js Tutorial

In this example:

• The App.vue file defines the structure, logic, and styling of the application in a single file component.
• message is a reactive property defined in the data() function and rendered in the template using {{ }}.
• The application is mounted to the #app div in index.html (automatically generated in the Vue project setup).

Why Learn Vue.js?

• Lightweight and easy to integrate with existing projects.
• Offers excellent performance for small- to medium-sized applications.
• Supports two-way data binding and reactivity.
• Backed by a robust community and extensive documentation.
