+
+// Enhanced methods
+clearRequestTimeouts() { /* cleanup logic */ }
+setLoading(loading) { /* loading state management */ }

+
+### Authentication Headers
+```http
+Authorization: Bearer <jwt_token>
+Content-Type: application/json
+```
+
+## Base URL
+```
+Development: http://localhost:3000/api
+Production: https://your-domain.com/api

+
+### JavaScript Examples
+
+#### Using Fetch API
+```javascript
+// Get DMS Settings
+const response = await fetch('/api/dms/settings', {
+  headers: {

+```
+
+#### Using Nuxt useFetch
+```javascript
+// In Vue component
+const { data, error } = await useFetch('/api/dms/settings', {
+  headers: {
+    'Authorization': `Bearer ${token}`
+  }
+});
+
+// Update settings
+const { data: updateResult } = await useFetch('/api/dms/settings', {
+  method: 'POST',
+  body: {
+    access: {
+      rbacEnabled: true
+    }
+  }
+});
+```
+
+## Pagination

+
+**Query Parameters:**
+- `page`: Page number (default: 1)
+- `limit`: Items per page (default: 20, max: 100)
+- `sort`: Sort field
+- `order`: Sort order (`asc` or `desc`)
+
+**Response Format:**
+```json
+{
+  "statusCode": 200,
+  "message": "Success",
+  "data": {
+    "items": [...],
+    "pagination": {
+      "currentPage": 1,
+      "totalPages": 5,
+      "totalItems": 100,
+      "limit": 20,
+      "hasNext": true,
+      "hasPrev": false
+    }
+  }
+}
+```
+
+## WebSocket Events
+Real-time features use WebSocket connections:
+
+### Connection
+```javascript
+const socket = io('/dms', {
+  auth: {
+    token: 'your_jwt_token'
+  }
+});
+```
+
+### Events
+- `document:uploaded` - New document uploaded
+- `access:requested` - Access request submitted
+- `access:approved` - Access request approved
+- `access:rejected` - Access request rejected
+- `system:maintenance` - System maintenance mode
+
+## SDKs and Libraries
+
+### JavaScript SDK
+```javascript
+import { EDMSClient } from '@edms/js-sdk';
+
+const client = new EDMSClient({
+  baseURL: 'https://your-domain.com/api',
+  token: 'your_jwt_token'
+});
+
+// Get settings
+const settings = await client.dms.getSettings();
+
+// Update settings
+await client.dms.updateSettings({
+  access: { rbacEnabled: true }
+});
+```

+- ✅ **Added Installation Guide**: Comprehensive setup instructions with environment configuration
+- ✅ **Added Project Structure**: Detailed directory structure documentation
+
+### 2. Code Quality Improvements
+- ✅ **Component Documentation**: Updated technical guide with accurate component inventory
+- ✅ **Error Handling Review**: Verified comprehensive error handling in stores
+- ✅ **Type Safety**: Confirmed proper PropTypes and component definitions
+
+### 3. Performance Optimizations
+- ✅ **Lazy Loading**: Confirmed proper use of `defineAsyncComponent` in access-management.vue
+- ✅ **Component Splitting**: Large components properly organized (DMSExplorer.vue, UploadWithMetadataModal.vue)
+
+## Recommendations
+
+### 1. Component Management
+- **Keep** `RsApiTester.vue` and `RSCalendar.vue` as they may be used for development or future features
+- **Consider** moving development-only components to a separate `/dev-components` directory
+- **Add** component usage documentation comments in each component
+
+### 2. Code Organization
+- **Create** component categories in documentation (Core, DMS, Dev Tools, etc.)
+- **Implement** component dependency tracking
+- **Add** component usage examples in documentation
+
+### 3. Error Handling Enhancements
+- **Add** global error boundary components
+- **Implement** error logging service integration
+- **Add** user-friendly error messages
+
+### 4. Performance Monitoring
+- **Implement** component performance tracking
+- **Add** bundle size monitoring
+- **Consider** code splitting for large components
+
+### 5. Testing Strategy
+- **Add** unit tests for core components
+- **Implement** integration tests for DMS workflows
+- **Add** accessibility testing for UI components
+

+
+## Conclusion
+
+The EDMS codebase is well-structured with comprehensive functionality. The analysis revealed:
+
+- **Strong Architecture**: Well-organized component hierarchy with clear separation of concerns
+- **Comprehensive Features**: Full-featured DMS with proper access control and workflow management
+- **Good Development Practices**: Proper use of Vue 3 composition API, Pinia stores, and TypeScript
+- **Minimal Technical Debt**: Few unused components, good error handling, proper documentation structure
+
+The refactoring focused on documentation updates and code organization rather than major structural changes, indicating a healthy codebase foundation.
