From 1874b77896f77c4d68aaed9d429f806697abacd4 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Mon, 3 Nov 2025 14:06:17 -0800 Subject: [PATCH] feat: add ImageHandler with EXIF extraction and comprehensive MIME detection (v5.2.0) Implements Phase 1.5 (Comprehensive MIME Type Detection) and adds built-in image processing support to IntelligentImportAugmentation. **New Features:** - ImageHandler: Extracts image metadata (dimensions, format, color space) using sharp - EXIF extraction: Camera data, GPS, timestamps using exifr library - Support for JPEG, PNG, WebP, GIF, TIFF, BMP, SVG, HEIC, AVIF formats - MimeTypeDetector: Unified MIME type detection with magic byte support - FormatDetector: Enhanced with image format detection via MIME + magic bytes **Architecture Fixes:** - Fixed brain.import() augmentation pipeline integration (src/brainy.ts:3140-3154) - Added parameter spreading for ImportSource objects to enable augmentation access - Fixed metadata propagation through ImportCoordinator to final results - Added augmentation data check in ImportCoordinator.extract() **Integration:** - ImageHandler registered as built-in handler alongside CSV, Excel, PDF - Images import as 'media' entities with 'image' subtype - Full metadata preserved in knowledge graph entities - Configuration options: enableImage, extractEXIF, imageDefaults **Test Coverage:** - 15 integration tests (image-import.test.ts) - 100% passing - 27 unit tests (image-handler.test.ts) - 100% passing - Format detection tests for all supported image types - Error handling and resilience tests **Breaking Changes:** None - backward compatible Generated with Claude Code Co-Authored-By: Claude --- CHANGELOG.md | 114 +++ docs/augmentations/EXAMPLES.md | 669 +++++++++++++++++ docs/augmentations/FORMAT_HANDLERS.md | 687 ++++++++++++++++++ package-lock.json | 680 ++++++++++++++--- package.json | 5 + scripts/migrate-vfs-storage.ts | 269 +++++++ src/api/UniversalImportAPI.ts | 21 +- .../FormatHandlerRegistry.ts | 246 +++++++ .../IntelligentImportAugmentation.ts | 9 +- .../intelligentImport/handlers/base.ts | 35 + .../handlers/imageHandler.ts | 340 +++++++++ src/augmentations/intelligentImport/index.ts | 20 +- src/augmentations/intelligentImport/types.ts | 6 + src/brainy.ts | 30 +- src/import/FormatDetector.ts | 138 +++- src/import/ImportCoordinator.ts | 78 +- src/vfs/MimeTypeDetector.ts | 292 ++++++++ src/vfs/VirtualFileSystem.ts | 285 ++------ src/vfs/importers/DirectoryImporter.ts | 45 +- src/vfs/index.ts | 3 + src/vfs/types.ts | 10 +- tests/integration/image-import.test.ts | 361 +++++++++ .../format-handler-registry.test.ts | 437 +++++++++++ .../unit/augmentations/image-handler.test.ts | 316 ++++++++ .../unit/vfs/blob-storage-integration.test.ts | 187 +++++ tests/unit/vfs/mime-type-detection.test.ts | 230 ++++++ 26 files changed, 5079 insertions(+), 434 deletions(-) create mode 100644 docs/augmentations/EXAMPLES.md create mode 100644 docs/augmentations/FORMAT_HANDLERS.md create mode 100644 scripts/migrate-vfs-storage.ts create mode 100644 src/augmentations/intelligentImport/FormatHandlerRegistry.ts create mode 100644 src/augmentations/intelligentImport/handlers/imageHandler.ts create mode 100644 src/vfs/MimeTypeDetector.ts create mode 100644 tests/integration/image-import.test.ts create mode 100644 tests/unit/augmentations/format-handler-registry.test.ts create mode 100644 tests/unit/augmentations/image-handler.test.ts create mode 100644 tests/unit/vfs/blob-storage-integration.test.ts create mode 100644 tests/unit/vfs/mime-type-detection.test.ts diff --git a/CHANGELOG.md b/CHANGELOG.md index 0ae0ac7c..5a00340a 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -2,6 +2,120 @@ All notable changes to this project will be documented in this file.

Method + +The `canHandle()` method determines if your handler can process the given data. + +### Strategy 1: MIME Type Detection (Recommended) + +```typescript +canHandle(data: Buffer | string | { filename?: string; ext?: string }): boolean { + if (typeof data === 'object' && 'filename' in data) { + const mimeType = this.getMimeType(data) + return this.mimeTypeMatches(mimeType, [ + 'application/x-myformat', + 'application/myformat' + ]) + } + return false +} +``` + +✅ **Pros:** Automatic, comprehensive, works with 2000+ types +❌ **Cons:** Requires filename + +### Strategy 2: Magic Byte Detection + +```typescript +canHandle(data: Buffer | string | { filename?: string; ext?: string }): boolean { + if (Buffer.isBuffer(data)) { + // Check magic bytes + return ( + data[0] === 0x50 && // 'P' + data[1] === 0x4B && // 'K' + data[2] === 0x03 && + data[3] === 0x04 // ZIP signature + ) + } + return false +} +``` + +✅ **Pros:** Works without filename, robust +❌ **Cons:** Requires knowledge of format structure + +### Strategy 3: Combined Approach + +```typescript +canHandle(data: Buffer | string | { filename?: string; ext?: string }): boolean { + // Try MIME type first + if (typeof data === 'object' && 'filename' in data) { + const mimeType = this.getMimeType(data) + if (this.mimeTypeMatches(mimeType, ['application/x-myformat'])) { + return true + } + } + + // Fallback to magic bytes + if (Buffer.isBuffer(data)) { + return this.checkMagicBytes(data) + } + + return false +} +``` + +✅ **Pros:** Robust, works in all scenarios +❌ **Cons:** More complex + +--- + +## process() Method + +The `process()` method extracts structured data from the file. + +### Return Format + +```typescript +interface ProcessedData { + /** Format identifier */ + format: string + + /** Array of extracted entities */ + data: Array> + + /** Metadata about processing */ + metadata: { + rowCount: number + fields: string[] + processingTime: number + [key: string]: any + } + + /** Original filename (optional) */ + filename?: string +} +``` + +### Example: CAD File Handler + +```typescript +async process(data: Buffer | string, options: FormatHandlerOptions): Promise { + const startTime = Date.now() + const buffer = Buffer.isBuffer(data) ? data : Buffer.from(data) + + // Parse CAD file + const cad = await this.parseCAD(buffer) + + // Extract entities + const entities = [] + + // Main CAD document + entities.push({ + type: 'CADDocument', + filename: options.filename, + units: cad.units, + bounds: cad.bounds + }) + + // Layers + for (const layer of cad.layers) { + entities.push({ + type: 'CADLayer', + name: layer.name, + color: layer.color, + visible: layer.visible, + objectCount: layer.objects.length + }) + } + + // Objects + for (const obj of cad.objects) { + entities.push({ + type: 'CADObject', + objectType: obj.type, + layer: obj.layer, + geometry: obj.geometry, + properties: obj.properties + }) + } + + return { + format: 'cad', + data: entities, +

cad.objects.length, + units: cad.units + }, + filename: options.filename + } +} +``` + +### Best Practices + +1. **Always track processing time:** + ```typescript + const startTime = Date.now() + // ... processing ... + metadata.processingTime = Date.now() - startTime + ``` + +2. **Include rich metadata:** + ```typescript + metadata: { + rowCount: entities.length, + fields: ['type', 'name', ...], + processingTime: 123, + // Format-specific metadata + layerCount: 5, + objectCount: 150, + version: '2.0' + } + ``` + +3. **Handle errors gracefully:** + ```typescript + try { + const parsed = this.parse(buffer) + return { format: 'myformat', data: parsed, ... } + } catch (error) { + throw new Error( + `Failed to parse myformat: ${error instanceof Error ? error.message : String(error)}` + ) + } + ``` + +4. **Support progress reporting (optional):** + ```typescript + if (options.progressHooks?.onCurrentItem) { + options.progressHooks.onCurrentItem(`Processing layer ${i}/${total}`) + } + ``` + +--- + +## FormatHandlerRegistry + +### Global Registry + +Use the global registry for application-wide handlers: + +```typescript +import { globalHandlerRegistry } from

'@soulcraft/brainy/augmentations/intelligentImport' + +const registry = new FormatHandlerRegistry() +registry.registerHandler({ ... }) +``` + +### Lazy Loading + +Handlers are lazy-loaded for
