# TypeScript Dependency Reduction - Complete Guide

## Objective

Minimize TypeScript files by making the platform 95% data-driven, where functionality is defined through JSON configurations and Lua scripts rather than hardcoded TSX files.

## Current Architecture (Post-Iteration 25)

### Infrastructure Layer (TypeScript - Required)

These files MUST remain as TypeScript because they provide core platform functionality:

#### Core App Files (~300 lines)
- `App.tsx` - React application entry point, routing, authentication flow
- `ErrorFallback.tsx` - Error boundary component

#### Generic Renderers (~500 lines)
- `GenericPage.tsx` - Universal page renderer (supports 4 layouts)
- `RenderComponent.tsx` - Recursive component tree renderer

#### Data & Logic Engines (~800 lines)
- `Database.ts` - KV store wrapper, all data persistence
- `LuaEngine.ts` - Lua script executor with sandboxing
- `WorkflowEngine.ts` - Workflow execution engine

#### Type Definitions (~400 lines)
- `level-types.ts` - Core type definitions
- `builder-types.ts` - Builder-specific types
- `schema-types.ts` - Schema definitions
- `package-types.ts` - Package system types

#### Helper Libraries (~600 lines)
- `auth.ts` - Authentication utilities
- `utils.ts` - General utilities
- `component-registry.ts` - Component type registry
- `password-utils.ts` - Password & email utilities

#### Shadcn UI Components (~3000 lines)
- 45 components in `/components/ui/`
- Pre-built, reusable UI library
- Can't be replaced without losing design system

**Total Infrastructure: ~5600 lines of essential TypeScript**

### Content Layer (Can Be Pure Data)

These files contain content that can be defined as JSON + Lua:

#### ⚠️ To Be Removed (~1800 lines)
- `Level1.tsx` - Homepage content (400 lines)
- `Level2.tsx` - User dashboard content (500 lines)
- `Level3.tsx` - Admin panel content (450 lines)
- `Level4.tsx` - God tier builder (400 lines)
- `Level5.tsx` - Super god panel (350 lines)

These will be replaced by PageDefinitions in database.

#### ⚠️ Complex Components (~2500 lines)
These are partially data-driven but still have TSX:

- `Builder.tsx` - Visual builder interface
- `Canvas.tsx` - Drag-and-drop canvas
- `ComponentHierarchyEditor.tsx` - Tree editor
- `PropertyInspector.tsx` - Props editor
- `WorkflowEditor.tsx` - Workflow diagram
- `SchemaEditor.tsx` - Database schema editor
- `ThemeEditor.tsx` - Theme customizer
- `UserManagement.tsx` - User CRUD
- `PageRoutesManager.tsx` - Route config
- And 30+ more specialized components

**These should eventually be defined declaratively too!**

#### ✅ Already Declarative
- IRC Webchat - 100% JSON + Lua
- Forum components - Defined in packages
- All page content - Via PageDefinitionBuilder

## Reduction Roadmap

### Phase 1: ✅ COMPLETE (Iteration 24-25)
**Goal**: Create generic rendering infrastructure

✅ Created `GenericPage.tsx` - Universal page renderer
✅ Created `PageRenderer` system
✅ Created `PageDefinitionBuilder`
✅ Created modular seed data system (`/src/seed-data/`)
✅ Reduced `seed-data.ts` from 280 lines to 5 lines (98% reduction)
✅ Documented data-driven architecture

**Impact**: Foundation for procedural generation in place

### Phase 2: 🎯 NEXT (Iteration 26)
**Goal**: Replace hardcoded level files

Tasks:
1. Update `App.tsx` to use `GenericPage` for Level 1:
   ```tsx
   // OLD
   <Level1 onNavigate={handleNavigate} />
   
   // NEW
   <GenericPage 
     pageId="page_level1_home"
     user={currentUser}
     level={1}
     onNavigate={handleNavigate}
   />
   ```

2. Test Level 1 functionality:
   - Homepage renders correctly
   - Navigation works
   - God credentials display
   - Hamburger menu functions

3. Repeat for Level 2:
   ```tsx
   // OLD
   <Level2 user={currentUser} onLogout={handleLogout} onNavigate={handleNavigate} />
   
   // NEW
   <GenericPage 
     pageId="page_level2_dashboard"
     user={currentUser}
     level={2}
     onNavigate={handleNavigate}
     onLogout={handleLogout}
   />
   ```

4. Repeat for Level 3:
   ```tsx
   <GenericPage 
     pageId="page_level3_admin"
     user={currentUser}
     level={3}
     onNavigate={handleNavigate}
     onLogout={handleLogout}
   />
   ```

5. Delete TSX files:
   - ❌ Delete `Level1.tsx` (400 lines)
   - ❌ Delete `Level2.tsx` (500 lines)
   - ❌ Delete `Level3.tsx` (450 lines)

**Impact**: ~1350 lines of TSX removed, replaced by JSON configurations

### Phase 3: 📋 FUTURE (Iteration 27-30)
**Goal**: Make Level 4/5 data-driven

Current state:
- Level 4/5 have complex UI builders
- These are still hardcoded TSX
- Need to be procedurally generated

Strategy:
1. Create "Meta-Builder" - A builder that builds builders
2. Define Level 4/5 UI as component trees
3. Store in database like other pages
4. Render via GenericPage

Example:
```json
{
  "id": "page_level4_builder",
  "level": 4,
  "layout": "dashboard",
  "components": [
    {
      "type": "Sidebar",
      "children": [
        {
          "type": "SidebarItem",
          "props": {
            "label": "Pages",
            "icon": "File",
            "onClick": "script_navigate_pages"
          }
        },
        {
          "type": "SidebarItem",
          "props": {
            "label": "Components",
            "icon": "Cube",
            "onClick": "script_navigate_components"
          }
        }
      ]
    },
    {
      "type": "MainContent",
      "children": [
        {
          "type": "PageEditor",
          "props": {
            "pageId": "{{context.currentPageId}}"
          }
        }
      ]
    }
  ]
}
```

**Challenges:**
- Level 4/5 are self-referential (they edit themselves)
- Need bootstrap mechanism
- Complex interactions (drag-drop, code editors)
- Real-time preview

**Solutions:**
- Keep minimal "bootstrap" Level 4/5 TSX
- Move 90% of functionality to declarative definitions
- Use Lua for complex interactions
- Store editor state in database

**Impact**: ~2300 lines of TSX reduced to ~300 lines of bootstrap code

### Phase 4: 🚀 AMBITIOUS (Future)
**Goal**: Declarative specialized components

Current state:
- 30+ specialized components (PropertyInspector, WorkflowEditor, etc.)
- All hardcoded TSX
- Total: ~2500 lines

Vision:
- Define component editors as JSON + Lua
- Create generic "MetaComponent" renderer
- Store all UI definitions in database

Example:
```json
{
  "id": "component_property_inspector",
  "type": "MetaComponent",
  "definition": {
    "layout": "form",
    "fields": [
      {
        "name": "className",
        "type": "text",
        "label": "CSS Classes",
        "validator": "script_validate_css_classes"
      },
      {
        "name": "variant",
        "type": "select",
        "label": "Variant",
        "options": "{{lua:getVariantOptions(component.type)}}"
      }
    ],
    "actions": [
      {
        "label": "Save",
        "onClick": "workflow_save_component_props"
      }
    ]
  }
}
```

**Impact**: ~2000 lines of TSX converted to JSON

## Key Insights

### What Can't Be Removed
1. **React Framework Code** - App.tsx, main.tsx
2. **Generic Renderers** - GenericPage, RenderComponent
3. **Core Engines** - Database, LuaEngine, WorkflowEngine
4. **Type Definitions** - Essential for TypeScript compilation
5. **UI Library** - Shadcn components (or equivalent)

### What Should Be Removed
1. **Level-specific TSX files** - Replace with PageDefinitions
2. **Hardcoded page content** - Move to database
3. **Static component configurations** - Use JSON configs
4. **Hardcoded workflows** - Define as node graphs
5. **Inline business logic** - Extract to Lua scripts

### Benefits of Reduction

#### 1. Maintainability
- Less code to maintain
- Clear separation: infrastructure vs. content
- Easy to find and fix bugs

#### 2. Flexibility
- Change content without recompiling
- A/B test different UIs
- User-customizable interfaces

#### 3. Distribution
- Share pages/components as data
- Package ecosystem
- Version control for content

#### 4. Performance
- Smaller bundle size
- Lazy load content
- Dynamic optimization

#### 5. Accessibility
- Non-developers can contribute content
- Visual editors for all content
- No TypeScript knowledge required

## Implementation Guide

### Converting a TSX File to Declarative

**Before** (`Level1.tsx`):
```tsx
export function Level1({ onNavigate }: Level1Props) {
  const [menuOpen, setMenuOpen] = useState(false)
  
  return (
    <div className="min-h-screen bg-background">
      <header>
        <Button onClick={() => setMenuOpen(!menuOpen)}>
          <List />
        </Button>
      </header>
      
      <main className="container mx-auto py-12">
        <Card>
          <CardHeader>
            <CardTitle>Welcome to MetaBuilder</CardTitle>
          </CardHeader>
          <CardContent>
            <p>Build applications without code</p>
            <Button onClick={() => onNavigate(2)}>
              Get Started
            </Button>
          </CardContent>
        </Card>
      </main>
    </div>
  )
}
```

**After** (JSON in database):
```json
{
  "id": "page_level1_home",
  "level": 1,
  "title": "Home",
  "layout": "default",
  "components": [
    {
      "id": "header",
      "type": "Header",
      "props": {
        "className": "border-b"
      },
      "children": [
        {
          "id": "menu_button",
          "type": "Button",
          "props": {
            "variant": "ghost",
            "size": "icon"
          },
          "children": [
            {
              "id": "menu_icon",
              "type": "Icon",
              "props": {
                "name": "List"
              },
              "children": []
            }
          ],
          "events": {
            "onClick": "script_toggle_menu"
          }
        }
      ]
    },
    {
      "id": "main_container",
      "type": "Container",
      "props": {
        "className": "mx-auto py-12"
      },
      "children": [
        {
          "id": "hero_card",
          "type": "Card",
          "children": [
            {
              "id": "card_header",
              "type": "CardHeader",
              "children": [
                {
                  "id": "card_title",
                  "type": "CardTitle",
                  "props": {
                    "children": "Welcome to MetaBuilder"
                  },
                  "children": []
                }
              ]
            },
            {
              "id": "card_content",
              "type": "CardContent",
              "children": [
                {
                  "id": "description",
                  "type": "Text",
                  "props": {
                    "children": "Build applications without code"
                  },
                  "children": []
                },
                {
                  "id": "cta_button",
                  "type": "Button",
                  "props": {
                    "children": "Get Started",
                    "variant": "default"
                  },
                  "children": [],
                  "events": {
                    "onClick": "workflow_navigate_dashboard"
                  }
                }
              ]
            }
          ]
        }
      ]
    }
  ],
  "luaScripts": {
    "onLoad": "script_page_load_analytics"
  }
}
```

**Lua Scripts**:
```lua
-- script_toggle_menu.lua
function toggleMenu()
  local state = context.state.menuOpen or false
  context.setState({ menuOpen = not state })
  return true
end

return toggleMenu
```

```lua
-- script_page_load_analytics.lua
function logPageView()
  local userId = context.user.id or "anonymous"
  local timestamp = os.time()
  
  print("Page view: Level 1 by " .. userId .. " at " .. timestamp)
  
  -- Could also call workflow or external API
  return true
end

return logPageView
```

**Workflow**:
```json
{
  "id": "workflow_navigate_dashboard",
  "name": "Navigate to Dashboard",
  "nodes": [
    {
      "id": "check_auth",
      "type": "condition",
      "label": "Is Authenticated?",
      "config": {
        "condition": "context.user != null"
      }
    },
    {
      "id": "navigate_dashboard",
      "type": "action",
      "label": "Go to Dashboard",
      "config": {
        "action": "navigate",
        "target": 2
      }
    },
    {
      "id": "navigate_login",
      "type": "action",
      "label": "Go to Login",
      "config": {
        "action": "navigate",
        "target": 2
      }
    }
  ],
  "edges": [
    { "source": "check_auth", "target": "navigate_dashboard", "label": "true" },
    { "source": "check_auth", "target": "navigate_login", "label": "false" }
  ]
}
```

**Rendered by**:
```tsx
<GenericPage 
  pageId="page_level1_home"
  user={currentUser}
  level={1}
  onNavigate={handleNavigate}
/>
```

## Conclusion

The path to minimal TypeScript dependency is clear:

1. ✅ **Phase 1 Complete**: Infrastructure in place
