+# Declarative Component System
+
+## Overview
+
+MetaBuilder now supports **declarative components** - components defined via JSON configuration and Lua scripts instead of traditional TSX files. This enables:
+
+- **Package-based components**: Components can be distributed as part of packages
+- **Dynamic loading**: Components are loaded at runtime from the package catalog
+- **Better separation**: Logic (Lua), UI (JSON), and rendering (React) are cleanly separated
+- **No code deployment**: New components can be added without code changes
+
+## Architecture
+
+### 1. Component Definition (JSON)
+
+Components are defined in package catalogs with:
+
+```typescript
+{
+  type: 'IRCWebchat',           // Component type identifier
+  category: 'social',            // Category for organization
+  label: 'IRC Webchat',         // Display name
+  description: '...',            // Description
+  icon: '💬',                    // Icon
+  props: [...],                  // Prop schema
+  config: {                      // UI structure
+    layout: 'Card',
+    styling: { className: '...' },
+    children: [...]              // Nested component tree
+  }
+}
+```
+
+### 2. Business Logic (Lua)
+
+Lua scripts handle component logic:
+
+```lua
+-- Send IRC Message
+function sendMessage(channelId, username, userId, message)
+  local msgId = "msg_" .. tostring(os.time()) .. "_" .. math.random(1000, 9999)
+  local msg = {
+    id = msgId,
+    channelId = channelId,
+    username = username,
+    userId = userId,
+    message = message,
+    type = "message",
+    timestamp = os.time() * 1000
+  }
+  log("Sending message: " .. message)
+  return msg
+end
+
+return sendMessage
+```
+
+### 3. Component Renderer (React)
+
+The renderer bridges JSON config, Lua scripts, and React:
+
+```typescript
+import { IRCWebchatDeclarative } from './IRCWebchatDeclarative'
+import { getDeclarativeRenderer } from '@/lib/declarative-component-renderer'
+
+// Check if component is declarative
+const renderer = getDeclarativeRenderer()
+if (renderer.hasComponentConfig('IRCWebchat')) {
+  return <IRCWebchatDeclarative {...props} />
+}
+```
+
+## IRC Webchat Example
+
+The IRC Webchat has been fully rewritten as a declarative component:
+
+### Package Definition
+
+Located in `src/lib/package-catalog.ts`:
+
+```typescript
+'irc-webchat': {
+  manifest: {
+    id: 'irc-webchat',
+    name: 'IRC-Style Webchat',
+    // ... metadata
+  },
+  content: {
+    schemas: [
+      // ChatChannel, ChatMessage, ChatUser schemas
+    ],
+    pages: [
+      // Page configuration
+    ],
+    luaScripts: [
+      {
+        id: 'lua_irc_send_message',
+        name: 'Send IRC Message',
+        code: '...',
+        parameters: [...],
+        returnType: 'table'
+      },
+      {
+        id: 'lua_irc_handle_command',
+        name: 'Handle IRC Command',
+        // Processes /help, /users, /clear, /me
+      },
+      {
+        id: 'lua_irc_format_time',
+        // Formats timestamps
+      },
+      {
+        id: 'lua_irc_user_join',
+        // Handles user joining
+      },
+      {
+        id: 'lua_irc_user_leave',
+        // Handles user leaving
+      }
+    ],
+    componentConfigs: {
+      IRCWebchat: {
+        // Full component configuration
+      }
+    }
+  }
+}
+```
+
+### Component Implementation
+
+`src/components/IRCWebchatDeclarative.tsx`:
+
+```typescript
+export function IRCWebchatDeclarative({ user, channelName = 'general', onClose }) {
+  const renderer = getDeclarativeRenderer()
+  
+  // Execute Lua script for sending messages
+  const handleSendMessage = async () => {
+    const newMessage = await renderer.executeLuaScript('lua_irc_send_message', [
+      `chat_${channelName}`,
+      user.username,
+      user.id,
+      trimmed,
+    ])
+    
+    if (newMessage) {
+      setMessages((current) => [...(current || []), newMessage])
+    }
+  }
+  
+  // Execute Lua script for commands
+  const handleCommand = async (command: string) => {
+    const response = await renderer.executeLuaScript('lua_irc_handle_command', [
+      command,
+      `chat_${channelName}`,
+      user.username,
+      onlineUsers || [],
+    ])
+    
+    if (response.message === 'CLEAR_MESSAGES') {
+      setMessages([])
+    } else {
+      setMessages((current) => [...(current || []), response])
+    }
+  }
+  
+  // UI rendering with shadcn components
+  return <Card>...</Card>
+}
+```
+
+## Key Files
+
+### Core System
+
+- `src/lib/declarative-component-renderer.ts` - Component renderer and Lua script executor
+- `src/lib/package-loader.ts` - Package initialization system
+- `src/lib/package-catalog.ts` - Package definitions including IRC
+- `src/components/RenderComponent.tsx` - Updated to support declarative components
+
+### IRC Implementation
+
+- `src/components/IRCWebchatDeclarative.tsx` - Declarative IRC component
+- ~~`src/components/IRCWebchat.tsx`~~ - **REMOVED** (replaced by declarative version)
+
+### Integration Points
+
+- `src/App.tsx` - Calls `initializePackageSystem()` on startup
+- `src/lib/component-catalog.ts` - IRC added to component catalog
+- `src/components/Level2.tsx` - Updated to use `IRCWebchatDeclarative`
+
+## Lua Script Execution
+
+Scripts are executed through the declarative renderer:
+
+```typescript
+const renderer = getDeclarativeRenderer()
+
+// Parameters are passed as array
+const result = await renderer.executeLuaScript('lua_irc_send_message', [
+  'channel_id',
+  'username',
+  'user_id',
+  'message text'
+])
+
+// Result contains the Lua function's return value
+console.log(result) // { id: "msg_...", message: "...", ... }
+```
+
+### Parameter Mapping
+
+The renderer wraps Lua code to map parameters:
+
+```typescript
+const wrappedCode = `
+${script.code}
+local fn = ...
+if fn then
+  local args = {}
+  table.insert(args, context.params.channelId)
+  table.insert(args, context.params.username)
+  // ... more parameters
+  return fn(table.unpack(args))
+end
+`
+```
+
+## Benefits
+
+1. **Modularity**: Components are self-contained in packages
+2. **Maintainability**: Logic (Lua), UI (JSON), rendering (React) are separated
+3. **Extensibility**: New components added without code changes
+4. **Testing**: Lua scripts can be tested independently
+5. **Distribution**: Packages can be shared as ZIP files
+6. **Security**: Lua sandbox prevents malicious code execution
+
+## Future Enhancements
+
+- [ ] Visual component builder for declarative components
+- [ ] Hot-reload for component definitions
+- [ ] Component marketplace
+- [ ] Version management for component definitions
+- [ ] Automated testing for Lua scripts
+- [ ] TypeScript type generation from JSON schemas
+- [ ] More built-in declarative components (Forum, Guestbook, etc.)
+
+## Migration Guide
+
+To convert an existing TSX component to declarative:
+
+1. **Define component config** in package catalog with props, layout, and children structure
+2. **Extract business logic** into Lua scripts (functions, event handlers)
+3. **Create declarative wrapper** component that uses `getDeclarativeRenderer()`
+4. **Register component** in component catalog
+5. **Update references** to use new declarative component
+6. **Test thoroughly** to ensure parity with original
+7. **Remove old TSX file** once verified
+
+## Example: Converting a Simple Component
+
+### Before (TSX):
+
+```tsx
+export function SimpleCounter() {
+  const [count, setCount] = useState(0)
+  
+  const increment = () => setCount(c => c + 1)
+  
+  return (
+    <Card>
+      <p>Count: {count}</p>
+      <Button onClick={increment}>Increment</Button>
+    </Card>
+  )
+}
+```
+
+### After (Declarative):
+
+**Package Definition:**
+```typescript
+{
+  componentConfigs: {
+    SimpleCounter: {
+      type: 'SimpleCounter',
+      props: [],
+      config: { layout: 'Card', children: [...] }
+    }
+  },
+  luaScripts: [{
+    id: 'lua_counter_increment',
+    code: 'function increment(count) return count + 1 end; return increment'
+  }]
+}
+```
+
+**Component:**
+```typescript
+export function SimpleCounterDeclarative() {
+  const [count, setCount] = useState(0)
+  const renderer = getDeclarativeRenderer()
+  
+  const increment = async () => {
+    const newCount = await renderer.executeLuaScript('lua_counter_increment', [count])
+    setCount(newCount)
+  }
+  
+  return <Card>...</Card>
+}
+```

-### 7. Docker-Style Package System
+### 7. Declarative Component System (IRC Implementation)
+**Functionality:** Components defined declaratively via JSON configuration and Lua scripts instead of TSX files, enabling package-based component distribution
+**Purpose:** Allow components to be part of packages, enabling dynamic loading and better separation of concerns
+**Trigger:** Component type registered in package catalog, loaded at app initialization
+**Progression:** Package defines component config in JSON → Lua scripts handle logic → Component renderer uses config → User adds component to page → Component renders using declarative definition
+**Success Criteria:**
+- IRC Webchat fully implemented as declarative component
+- Component configuration stored in package catalog
+- Lua scripts handle message sending, commands, user join/leave
+- Component props defined in JSON schema
+- UI layout defined in JSON structure
+- Original IRCWebchat.tsx removed
+- Declarative version fully functional in Level 2
+- Package system loads all component definitions on startup
+
+### 8. Docker-Style Package System
 **Functionality:** Browse, install, and manage pre-built applications (forum, guestbook, video platform, music streaming, games, e-commerce) that integrate with existing infrastructure
 **Purpose:** Allow users to rapidly deploy complete applications without building from scratch, leveraging existing database and workflow systems
 **Trigger:** User navigates to "Packages" tab in god-tier panel
