VueJS - Vue CLI Installation

Instructions on installing and using the Vue Command Line Interface

The Vue Command Line Interface (Vue CLI) is a powerful tool for scaffolding and managing VueJS projects. This guide provides step-by-step instructions on installing Vue CLI, creating a new project, and using various Vue CLI commands.

Installing Vue CLI

Step 1: Install Node.js and npm

Vue CLI requires Node.js and npm (Node Package Manager) to be installed on your system. Download and install the latest version of Node.js from the official website:

# Download and install Node.js from https://nodejs.org/
# Verify the installation
$ node -v
$ npm -v
                

Step 2: Install Vue CLI Globally

Install Vue CLI globally 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 3: Verify the Installation

Verify that Vue CLI is installed correctly by checking its version:

# Verify Vue CLI installation
$ vue --version
                

Creating a New VueJS Project

Step 1: Create a Project

Use Vue CLI to create a new VueJS project. Run the following command and follow the prompts to set up your project:

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

Step 2: Navigate to the Project Directory

Navigate to your new project's directory:

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

Step 3: 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.

Using Vue CLI Commands

Build Commands

Use Vue CLI commands to build and serve your project:

# Build the project for production
$ npm run build

# Lint and fix files
$ npm run lint
                

Adding Plugins

Vue CLI allows you to add plugins to your project to extend its functionality:

# Add a plugin (example: Vue Router)
$ vue add router

# Add a plugin (example: Vuex)
$ vue add vuex
                

Running Tests

Vue CLI provides commands for running unit and end-to-end tests:

# Run unit tests
$ npm run test:unit

# Run end-to-end tests
$ npm run test:e2e
                

Best Practices

Follow these best practices when using Vue CLI:

• Use Version Control: Use Git to track changes and collaborate with your team.
• Keep Dependencies Updated: Regularly update your project's dependencies to ensure you have the latest features and security fixes.
• Configure Linting and Formatting: Set up ESLint and Prettier to maintain code quality and consistency.
• Leverage Vue DevTools: Use Vue DevTools for debugging and inspecting your VueJS applications.
• Document Your Setup: Document your project's setup and dependencies to help new team members get started quickly.
