# NaviDocs Backend API Routes - Implementation Complete ## Overview Successfully implemented 4 production-ready API route modules for NaviDocs server with comprehensive security, validation, and error handling. ## Files Created ### Core Route Modules #### 1. `/home/setup/navidocs/server/routes/upload.js` **POST /api/upload** - PDF upload endpoint - Multer integration for file upload - File validation (PDF only, max 50MB) - UUID generation for documents - SHA256 hash calculation for deduplication - Database record creation in `documents` table - OCR job queue creation in `ocr_jobs` table - BullMQ job dispatch - Returns `{ jobId, documentId }` **Security Features:** - Extension validation (.pdf only) - MIME type verification via magic numbers - File size enforcement (50MB) - Filename sanitization - Path traversal prevention - Null byte filtering #### 2. `/home/setup/navidocs/server/routes/jobs.js` **GET /api/jobs/:id** - Job status endpoint - Query `ocr_jobs` table by job UUID - Returns `{ status, progress, error, documentId }` - Status values: pending, processing, completed, failed - Includes document info when completed **GET /api/jobs** - List jobs endpoint - Filter by status - Pagination support (limit, offset) - User-scoped results - Returns job list with document metadata #### 3. `/home/setup/navidocs/server/routes/search.js` **POST /api/search/token** -

Endpoint specifications - Request/response formats - Authentication requirements - Security features - Error handling - Testing examples - Environment variables #### 2. `/home/setup/navidocs/server/API_SUMMARY.md` Implementation summary - File listing - API endpoint details - Security implementation - Database schema integration - Dependencies - Testing guide - Next steps ### Testing #### `/home/setup/navidocs/server/test-routes.js` Route verification script - Validates all routes load correctly - Lists all endpoints - Syntax verification ## API Endpoints Summary ``` POST /api/upload - Upload PDF file GET /api/jobs/:id - Get job status GET /api/jobs - List jobs POST /api/search/token - Generate tenant token POST /api/search - Server-side search GET /api/search/health - Search health check GET /api/documents/:id - Get document metadata GET /api/documents - List documents DELETE /api/documents/:id - Delete document ``` ## Security Features ### File Upload Security - Extension whitelist (.pdf only) - MIME type verification (magic numbers) - File size limits (50MB) - Filename sanitization - Path traversal prevention -
