From 4785d23179f6144e0134235e5e7e60ebeedfa096 Mon Sep 17 00:00:00 2001 From: Oleg Proskurin Date: Sun, 9 Nov 2025 22:41:59 +0700 Subject: [PATCH] feat: implement Phase 4 image management with upload and CRUD endpoints MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement complete image management system with file upload, listing, retrieval, updates, alias assignment, and soft deletion. **v1 API Routes:** - `POST /api/v1/images/upload` - Upload single image file with database record - `GET /api/v1/images` - List images with filters and pagination - `GET /api/v1/images/:id` - Get single image by ID - `PUT /api/v1/images/:id` - Update image metadata (alias, focal point, meta) - `PUT /api/v1/images/:id/alias` - Assign project-scoped alias to image - `DELETE /api/v1/images/:id` - Soft delete image **Upload Endpoint Features:** - Uses uploadSingleImage middleware for file handling - Creates database record with image metadata - Stores file in MinIO storage (uploads category) - Supports optional alias and flowId parameters - Returns ImageResponse with all metadata **Route Features:** - Authentication via validateApiKey middleware - Project key requirement - Rate limiting on upload endpoint - Request validation with pagination - Error handling with proper status codes - Response transformation with toImageResponse converter - Project ownership verification for all operations **ImageService Integration:** - Uses existing ImageService methods - Supports filtering by flowId, source, alias - Soft delete with deletedAt timestamp - Alias validation and conflict detection **Type Updates:** - Updated ImageFilters with explicit | undefined for optional properties - All response types already defined in responses.ts **Technical Notes:** - Upload creates both storage record and database entry atomically - Focal point stored as JSON with x/y coordinates - Meta field for flexible metadata storage - File hash set to null (TODO: implement hashing) - All Phase 4 code is fully type-safe with zero TypeScript errors 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- apps/api-service/src/routes/v1/images.ts | 363 +++++++++++++++++++++++ apps/api-service/src/routes/v1/index.ts | 2 + apps/api-service/src/types/models.ts | 8 +- 3 files changed, 369 insertions(+), 4 deletions(-) create mode 100644 apps/api-service/src/routes/v1/images.ts diff --git a/apps/api-service/src/routes/v1/images.ts b/apps/api-service/src/routes/v1/images.ts new file mode 100644 index 0000000..1a962ea --- /dev/null +++ b/apps/api-service/src/routes/v1/images.ts @@ -0,0 +1,363 @@ +import { Response, Router } from 'express';
