How to Install Dependencies for the AI For Beginners Quiz App

TLDR: Navigate to the etc/quiz-app directory in the microsoft/AI-For-Beginners repository and run npm install to install Vue 2, Vue Router, and development tools declared in package.json, then use npm run serve to start the development server.

The AI For Beginners quiz application is a Vue 2-based interactive tool located in the etc/quiz-app directory of the microsoft/AI-For-Beginners repository. To begin development or customize the quiz interface, you must first install dependencies for the AI For Beginners quiz app using the Node package manager.

Prerequisites

Before installing, ensure you have Node.js LTS version 14 or higher installed on your system. The Vue CLI toolchain and peer dependency resolution require a recent LTS release to function correctly.

Step 1: Navigate to the Quiz App Directory

All npm commands must be executed from within the etc/quiz-app folder so that the correct package.json is detected. From the repository root, change to the application directory:

cd etc/quiz-app

Step 2: Install NPM Dependencies

Run the install command to resolve the exact versions listed in the project's package.json, which creates a node_modules directory containing the complete dependency tree:

npm install

This command installs runtime libraries including vue, vue-router, and vue-i18n under dependencies, alongside development tools such as @vue/cli-service, eslint, and babel-eslint under devDependencies as specified in the source configuration.

Step 3: Verify the Installation

After installation completes, validate that the environment is configured correctly by running the linting script defined in package.json:

npm run lint

This executes ESLint to ensure the installed packages and codebase conform to the project's coding standards.

Run the Development Server

Once dependencies are installed, start the hot-reloading development server:

npm run serve

This launches the application at http://localhost:8080, utilizing the installed @vue/cli-service to compile the Vue 2 source code.

Build for Production

To compile the application for deployment:

npm run build

This outputs the production bundle to the dist/ directory, processing the source through the Babel configuration defined in babel.config.js.

Key Configuration Files

Understanding how the quiz app manages its requirements requires examining several critical files:

• etc/quiz-app/package.json — Declares all runtime and build-time dependencies, including the exact versions of Vue 2, Vue Router, and internationalization libraries, plus npm scripts for serve, build, and lint.

• etc/quiz-app/README.md — Contains the official setup instructions that document the npm install command and additional usage details for the quiz application.

• etc/quiz-app/babel.config.js — Configures the Babel transpiler that processes modern JavaScript for browser compatibility, utilized by the Vue CLI service during both development and production builds.

• etc/quiz-app/src/main.js — The application entry point that initializes the Vue instance and wires together installed packages like vue-router and vue-i18n.

• etc/quiz-app/src/router/index.js — Configures client-side routing using the vue-router dependency installed from package.json.

Summary

• The quiz application resides in etc/quiz-app and requires Node.js LTS ≥ 14.
• Execute npm install from the etc/quiz-app directory to install Vue 2, Vue Router, and development tools listed in package.json.
• Verify the setup with npm run lint to ensure the ESLint configuration loads properly.
• Use npm run serve for local development at localhost:8080 and npm run build for production deployment to the dist/ folder.
• Critical configuration files include package.json, babel.config.js, and the entry points in src/main.js and src/router/index.js.

Frequently Asked Questions

What Node.js version is required to install dependencies for the AI For Beginners quiz app?

The installation process requires Node.js LTS version 14 or higher. While the application may function on newer versions, using a recent LTS release ensures compatibility with the Vue CLI toolchain and proper peer dependency resolution.

Where must I run the npm install command for the quiz app?

You must run npm install from within the etc/quiz-app directory specifically. Running the command from the repository root will fail because npm locates the package.json file relative to the current working directory, and the quiz app's dependencies are isolated in the etc/quiz-app subdirectory.

How do I handle permission errors during npm install on Linux or macOS?

If you encounter permission issues during installation, use a Node version manager such as nvm to manage Node.js versions without requiring elevated privileges. Alternatively, you can append the --legacy-peer-deps flag to the install command, though the default configuration normally installs without additional flags on properly configured systems.

Can I run the quiz app immediately after installing dependencies?

Yes, once npm install completes successfully, you can immediately start the development server by running npm run serve from the same etc/quiz-app directory. This command utilizes the installed @vue/cli-service to compile the Vue 2 application and serve it at http://localhost:8080 with hot-reloading enabled.
