In this tutorial, I will take you through a crash course on Vue JS – a popular JavaScript framework for building dynamic web applications. By the end of this tutorial, you will have a solid understanding of Vue JS and will have built your first project using this framework.

What is Vue JS?

Vue JS is a progressive JavaScript framework for building user interfaces. It is designed to be incrementally adoptable, meaning that you can start using it on small parts of your project and gradually scale it up to handle more complex applications. Vue JS is popular for its simplicity and ease of use, making it a great choice for web developers of all skill levels.

Getting Started with Vue JS

To get started with Vue JS, you will need to first install it on your machine. You can do this by including the Vue CDN in your HTML file or by using a package manager like npm or yarn.

Here is an example of how to include Vue JS using the CDN:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Vue JS Tutorial</title>
    <script src="https://cdn.jsdelivr.net/npm/vue@2.6.14/dist/vue.js"></script>
</head>
<body>
    <div id="app">
        {{ message }}
    </div>

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

In this example, we are including Vue JS using the CDN and creating a new Vue instance with a data property called message. We are then binding this property to the #app element in the HTML, which will display the message "Hello, Vue!" on the page.

Vue JS Directives

Vue JS makes use of directives to add dynamic behavior to the HTML elements. Directives are special attributes that are prefixed with v-, such as v-bind and v-model.

Here are some commonly used directives in Vue JS:

v-bind: Binds the value of an expression to an HTML attribute.
v-model: Binds the value of an input field to a data property.
v-for: Loops through an array and renders an HTML element for each item.
v-if and v-else: Conditionally renders an HTML element based on a boolean expression.

Building Your First Vue JS Project

Now that you have a basic understanding of Vue JS, let’s build your first project using this framework. In this project, we will create a simple to-do list application.

First, create a new HTML file and include the Vue CDN as shown in the previous example. Next, add the following code to create the to-do list application:

<div id="app">
    <input type="text" v-model="newTodo" @keyup.enter="addTodo">
    <ul>
        <li v-for="(todo, index) in todos" :key="index">{{ todo }}</li>
    </ul>
</div>

<script>
    var app = new Vue({
        el: '#app',
        data: {
            newTodo: '',
            todos: []
        },
        methods: {
            addTodo: function() {
                if(this.newTodo.trim() !== '') {
                    this.todos.push(this.newTodo);
                    this.newTodo = '';
                }
            }
        }
    });
</script>

In this code, we have a text input field that allows users to enter a new to-do item. When the user presses the Enter key, the addTodo method is called, which adds the new item to the todos array. Finally, we loop through the todos array and display each item in a list format.

Conclusion
