Welcome to the Vue.js tutorial! Vue.js is a progressive JavaScript framework used for building user interfaces and single-page applications. It is known for its simplicity, efficiency, and reactivity system.

What is Vue.js?

Vue.js is an open-source JavaScript framework created by Evan You. It is designed to be incrementally adoptable, making it easy to integrate with other libraries or existing projects. Vue.js is also known for its gentle learning curve, making it accessible to beginners and experienced developers alike.

Getting Started

Before you start learning Vue.js, you need to have Node.js installed on your machine. Node.js is a runtime for JavaScript that allows you to run JavaScript code outside of a browser. You can download and install Node.js from here.

Once Node.js is installed, you can create a new Vue.js project using the Vue CLI (Command Line Interface):

npm install -g @vue/cli
vue create my-vue-project

Basic Structure

A Vue.js application typically consists of the following files:

  • index.html: The main HTML file where the Vue.js application is mounted.
  • main.js: The main JavaScript file where the Vue.js instance is created and configured.
  • App.vue: The main component that represents the root component of the application.

Components

Vue.js uses a component-based architecture, which allows you to build reusable and maintainable code. Components are self-contained and can be used in multiple places within your application.

Here's an example of a simple Vue.js component:

<template>
  <div>
    <h1>{{ title }}</h1>
    <p>{{ description }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      title: 'Welcome to Vue.js!',
      description: 'Vue.js is a progressive JavaScript framework.'
    };
  }
};
</script>

<style>
h1 {
  color: #333;
}
</style>

Reactive Data

Vue.js uses a reactive data system that automatically updates the DOM when the data changes. This makes it easy to create dynamic and interactive user interfaces.

Here's an example of how to use reactive data in a Vue.js component:

<template>
  <div>
    <input v-model="message" placeholder="Type something...">
    <p>{{ message }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: ''
    };
  }
};
</script>
