Phase 4: Complete JSON-Driven Refactoring

Overview

Complete transformation of the CodeForge app into a fully JSON-driven architecture with comprehensive hook library and components under 150 LOC.

Architecture Principles

1. Separation of Concerns

• Hooks: All business logic, data management, API calls
• Components: Pure presentation, under 150 LOC
• JSON: Page structure, component trees, actions, data sources

2. JSON-Driven Everything

• Page definitions
• Component trees
• Data sources and transformations
• Actions and event handlers
• Hook configurations
• Seed data

3. Composable & Testable

• Small, focused hooks
• Reusable components
• Type-safe JSON schemas
• Easy to test in isolation

Implementation Plan

Phase 4A: Core Hook Library ✅

5. Integration hooks

Phase 4B: JSON Orchestration Engine ✅

1. Page schema definitions
2. Component registry
3. Action executor
4. Data source manager
5. Hook orchestrator

Phase 4C: Component Atomization ✅

1. Break down large components
2. Create atomic components
3. Refactor to use hooks
4. Ensure < 150 LOC

Phase 4D: Integration & Testing ✅

1. Wire up JSON pages
2. Test all features
3. Migrate existing pages
4. Documentation
