Portfolio JavaScript Architecture

This directory contains the modular JavaScript architecture for the portfolio website, following the Single Responsibility Principle (SRP) and modern ES6 module patterns.

🏗️ Architecture Overview

Single Responsibility Principle (SRP)

Each class has a single, well-defined responsibility:

• ThemeManager: Handles theme switching and persistence
• PerformanceMonitor: Monitors and optimizes performance
• ParticleSystem: Manages background particle animations
• TypingAnimation: Handles typewriter text effects
• NavigationEffects: Manages navbar scroll effects
• MobileNavigation: Handles mobile menu functionality
• SmoothScrolling: Manages smooth anchor link scrolling
• InteractiveElements: Handles interactive UI effects
• CursorEffects: Manages custom cursor effects
• ScrollAnimations: Handles scroll-triggered animations
• PortfolioApp: Orchestrates all components

Event-Driven Communication

Components communicate through custom events rather than direct references:

• themeChanged: Dispatched when theme changes
• performanceWarning: Dispatched when performance issues detected

ES6 Modules

• Uses modern ES6 import/export syntax
• Each class is in its own file
• Clear dependency management
• Better tree-shaking and bundling support

🚀 Usage

Main Entry Point

// main.js
import { PortfolioApp } from './core/PortfolioApp.js';

document.addEventListener('DOMContentLoaded', () => {
    window.portfolioApp = new PortfolioApp();
});

Component Access

// Access any component through the main app
const themeManager = window.portfolioApp.getComponent('themeManager');
const particleSystem = window.portfolioApp.getComponent('particleSystem');

Adding New Components

1. Create a new class file in the appropriate directory
2. Export the class using ES6 export syntax
3. Import and initialize in PortfolioApp.js
4. Add to the components Map

🔧 Development

Adding a New Feature

1. Create the component class in the appropriate directory
2. Follow the naming convention: PascalCase.js
3. Export the class: export class ComponentName
4. Add to PortfolioApp: Import and initialize in the main app
5. Document the component: Add to this README

Component Template

/**
 * Component Name
 * Brief description of responsibility
 */
export class ComponentName {
    constructor() {
        this.init();
    }

    init() {
        // Initialize component
    }

    // Component methods
}

📊 Benefits

Maintainability

• Each component is focused and easy to understand
• Changes to one component don’t affect others
• Clear separation of concerns

Testability

• Each component can be tested independently
• Easy to mock dependencies
• Clear interfaces between components

Scalability

• Easy to add new features
• Components can be reused
• Clear architecture for team development

Performance

• Better tree-shaking
• Lazy loading support
• Optimized bundling

🛠️ Build Process

The modular structure supports modern build tools:

• Webpack: For bundling and optimization
• Rollup: For tree-shaking and ES6 modules
• Vite: For fast development and building
• Parcel: For zero-config bundling

🔍 Debugging

Component Debugging

// Access component for debugging
console.log(window.portfolioApp.getComponent('themeManager'));

// Check if component exists
if (window.portfolioApp.getComponent('particleSystem')) {
    console.log('Particle system is active');
}

Event Debugging

// Listen to custom events
document.addEventListener('themeChanged', (event) => {
    console.log('Theme changed to:', event.detail.theme);
});

document.addEventListener('performanceWarning', (event) => {
    console.log('Performance warning:', event.detail);
});

📝 Best Practices

1. Single Responsibility: Each class should have one clear purpose
2. Event-Driven: Use custom events for component communication
3. Error Handling: Always handle potential errors gracefully
4. Documentation: Document each component’s purpose and usage
5. Naming: Use clear, descriptive names for classes and methods
6. Testing: Write tests for each component independently

🔄 Migration from Monolithic

This modular structure replaces the previous monolithic main.js file. Benefits:

• Before: 774 lines in a single file
• After: 11 focused modules with clear responsibilities
• Maintainability: Significantly improved
• Team Development: Multiple developers can work on different components
• Code Reuse: Components can be reused in other projects
