Web Form v4 - Component-Based Architecture

A sophisticated web form application built with a modular handler architecture and comprehensive context management system.

🏗️ Architecture Overview

This project implements a clean separation of concerns through specialized handlers:

• IO Handler - Captures all user input events (mouse, keyboard, touch)
• Interface Handler - Manages component interactions and state
• Event Handler - Enforces singleton locks and prevents conflicting operations
• ChangeLog System - Coordinates communication between handlers

🎯 Key Features

Handler Chain Architecture

User Input → IO Handler → Interface Handler → Event Handler
     ↓              ↓              ↓              ↓
  Captures      Detects        Applies       Prevents
   Events      Components      Locks        Conflicts

Context Management

• Comprehensive state tracking - Mouse, keyboard, component states
• Real-time synchronization - All handlers stay informed of changes
• Conflict prevention - Singleton locks prevent simultaneous operations
• Performance monitoring - Track system performance and optimization

Component System

• Reactive components - Declare capabilities, don't handle events directly
• Behavior separation - Logic separated from presentation
• Schema-driven - Components register functions and triggers with event system

🚀 Getting Started

1. Clone the repository

   git clone [repository-url]
   cd web-form-v4

2. Open index.html in a modern browser

3. Development workflow

   • Components declare their capabilities in Behavior.js files
   • Event Handler automatically wires up user inputs to component functions
   • No direct event listeners in components - all handled centrally

📋 Development Guidelines

Creating New Components

1. Extend BaseContainer class
2. Create separate Behavior.js file for interactions
3. Register capabilities with event handler schema
4. Let handlers manage all user input events

Handler Responsibilities

• IO Handler: Raw input capture only
• Interface Handler: Component state management
• Event Handler: Operation coordination and conflict prevention

🔧 Current Status

• ✅ Core handler architecture implemented
• ✅ Context management system active
• ✅ Component base class with comprehensive properties
• ✅ Inter-handler communication via changelog
• ⚠️ ~75% of context properties need handlers (see context_coverage_analysis.md)
• 🚧 Additional managers needed (Selection, Performance, State, etc.)

📊 Coverage Analysis

Current handler coverage of context properties:

• Fully Covered: 26% (Input tracking, component interaction, locks)
• Partially Covered: 26% (Basic operations, modal states)
• Not Covered: 47% (Selection, performance, validation, animations)

See App/Context/context_coverage_analysis.md for detailed breakdown.

🎮 Handler Communication

All handlers communicate through a shared context system:

• Real-time change detection via polling
• JSON-based changelog for inter-handler messages
• Conflict resolution through priority-based locking
• Automatic cleanup and retention policies

🧩 Component Philosophy

"Components are REACTIVE, not PROACTIVE"

Components declare what they can do, and the Event Handler decides when to do it. This creates:

• Consistent user experience
• Conflict-free operations
• Centralized coordination
• Reusable components

🤝 Contributing

1. Follow the reactive component philosophy
2. Use the changelog system for inter-handler communication
3. Register new capabilities through the schema system
4. Maintain separation of concerns between handlers
