• Frontend: HTML5, CSS3, JavaScript (ES6+)
• Images: SVG format for scalability
• Data Format: JSON for easy multilingual content management
• Browser Compatibility: Modern browsers (Chrome, Firefox, Safari, Edge)
• Deployment: Automatic deployment to GitHub Pages via GitHub Actions
• Testing: Jest framework with comprehensive unit tests
• Containerization: Docker support with Node.js Alpine base image
• Registry: GitHub Container Registry (GHCR) for container distribution

The game is automatically deployed to GitHub Pages using GitHub Actions whenever changes are pushed to the main branch. The deployment workflow:

1. Triggers: Automatically on push to main branch, or manually via GitHub Actions tab
2. Build: Sets up GitHub Pages environment and prepares static files
3. Deploy: Deploys the game to GitHub Pages at https://commjoen.github.io/Speller/

No build process is required since this is a static HTML/CSS/JavaScript application.

The application is also available as a Docker container published to GitHub Container Registry:

# Pull and run the latest container
docker pull ghcr.io/commjoen/speller:latest
docker run -p 8080:8000 ghcr.io/commjoen/speller:latest

# Access the game at http://localhost:8080

1. Clone and install dependencies:

   git clone https://github.com/commjoen/Speller.git
   cd Speller
   npm install

2. Run locally:

   # Option 1: Using npm
   npm start
   
   # Option 2: Using Docker
   docker build -t speller-local .
   docker run -p 8080:8000 speller-local

3. Run tests:

   # Run all tests
   npm test
   
   # Run tests in watch mode
   npm run test:watch

4. Development Tools:

   # Install pre-commit hooks (requires pip install pre-commit)
   pre-commit install
   
   # Run linting
   npm run lint
   npm run lint:fix
   
   # Format code
   npm run format
   npm run format:check
   
   # Run pre-commit hooks manually
   pre-commit run --all-files

To add new words or languages, edit the data.json file:

{
  "language_code": [
    {
      "sentence": "Example sentence with {blank} placeholder.",
      "word": "answer",
      "image": "images/answer.svg",
      "hint": "Optional hint text"
    }
  ]
}

• Scoring: 1 point per correct answer
• Case Insensitive: Answers are checked regardless of capitalization
• Visual Feedback: Correct answers show in green, incorrect in red
• Progress Tracking: Shows current question number and total questions
• Language Reset: Changing language resets the game and score

This game is designed to help with:

• Vocabulary Building: Learn new words in multiple languages
• Spelling Practice: Improve spelling accuracy
• Visual Association: Connect words with images for better retention
• Language Comparison: See how the same concepts are expressed in different languages

This repository includes automated security and dependency management:

• CodeQL Security Analysis: Automated code scanning for security vulnerabilities and coding errors runs on every push, pull request, and weekly
• Renovate Bot: Automated dependency updates for npm packages, Docker base images, and GitHub Actions
• Vulnerability Alerts: Automatic security alerts for known vulnerabilities in dependencies

The project uses Semantic Versioning and automated releases:

• Semantic Release: Automatically generates version numbers and changelogs based on commit messages
• Version Display: The current version is displayed in the web app UI with multilingual support
• Automated Tagging: GitHub releases are automatically created with each version bump
• Changelog: All changes are documented in CHANGELOG.md

Releases are triggered automatically when changes are pushed to the main branch:

1. Commit Analysis: Semantic Release analyzes commit messages to determine version bump
2. Version Update: Updates package.json and generates changelog
3. GitHub Release: Creates a tagged release with release notes
4. NPM Publish: Publishes the package to npm (if configured)

The application displays the current version in the header:

• English: "Version: X.Y.Z"
• Dutch: "Versie: X.Y.Z"
• German: "Version: X.Y.Z"

Renovate is configured to:

• Group related updates together (e.g., all GitHub Actions updates in one PR)
• Schedule updates for Monday mornings to minimize disruption
• Automatically merge trusted updates like GitHub Actions
• Maintain separate groups for development vs production dependencies
