VueJS - Creating Your First VueJS Application

Creating Your First VueJS Application

This guide walks you through creating your first VueJS application. You will learn how to set up a VueJS project, create components, and manage data to build a simple, functional application.

Setting Up the Project

Step 1: Install Vue CLI

If you haven't already installed Vue CLI, you can do so using npm or yarn:

# Install Vue CLI using npm
$ npm install -g @vue/cli

# Install Vue CLI using yarn
$ yarn global add @vue/cli
                

Step 2: Create a New VueJS Project

Create a new VueJS project using Vue CLI:

# Create a new VueJS project
$ vue create my-first-vue-app
                

Step 3: Navigate to the Project Directory

Navigate to your new project's directory:

# Navigate to the project directory
$ cd my-first-vue-app
                

Step 4: Serve the Project

Start the development server to serve your VueJS project locally:

# Serve the VueJS project
$ npm run serve
                

Open your browser and navigate to http://localhost:8080 to see your VueJS application in action.

Creating Components

Step 1: Create a New Component

Create a new component file in the src/components directory:

// src/components/HelloWorld.vue





                

Step 2: Use the Component

Import and use the new component in your main App.vue file:

// src/App.vue



                

Managing Data

Step 1: Add Data to the Component

Add a data property to your component and bind it to the template:

// src/components/HelloWorld.vue





                

Step 2: Update Data Dynamically

Add a method to update the data dynamically and bind it to a button click event:

// src/components/HelloWorld.vue
