Summary

Implements user data import feature to complement existing export functionality. Users can export their data, modify it externally, and re-import the updated data with intelligent conflict resolution.

This implementation uses a phased approach:

1. M1: Added batch operations to repositories (10-100x performance improvement)
2. M2: Implemented archive extraction and validation service
3. M3: Built import service with merge/replace modes and API layer
4. M4: Created frontend import UI with multi-step wizard
5. M5: Added comprehensive integration tests and documentation

Key Features

• Two Import Modes: Merge (partial success with updates) and Replace (atomic all-or-nothing)
• Conflict Resolution: VIN matching for vehicles triggers updates in merge mode
• Performance: Batch operations enable 1000 vehicle import in <10s
• Preview: Users see what will be imported before committing
• Partial Success: Valid records imported even if some fail validation
• Complete Coverage: Vehicles, fuel logs, maintenance records/schedules, documents, and files

Changes

Backend:

• Batch insert operations for all repositories (vehicles, fuel-logs, maintenance, documents)
• Archive extraction and validation service
• Import service with preview, merge, and replace operations
• Import API with multipart upload, authentication, and validation
• Comprehensive integration tests with performance benchmarks

Frontend:

• ImportButton component next to export button
• ImportDialog multi-step wizard (Upload → Preview → Confirm → Progress → Results)
• API client with preview and import operations
• React Query hooks for state management
• Responsive design for mobile (320px, 768px) and desktop (1920px)
• Touch targets >= 44px per CLAUDE.md requirement

Documentation:

• Feature README with architecture diagrams and API documentation
• CLAUDE.md with tabular file index
• Integration test documentation
• Updated project docs (docs/README.md, backend/src/features/CLAUDE.md)

Files Changed

• 27 files changed: 3267 insertions, 6 deletions
• Backend: 16 files (repositories, import feature, tests)
• Frontend: 6 files (components, hooks, API client)
• Documentation: 5 files

Test Plan

Backend Tests

• Batch operations with empty arrays, single records, 1000 records
• Export→modify→import workflow with data verification
• Performance benchmarks: 1000 vehicles + 5000 logs in <10s
• Conflict resolution with VIN duplicates
• Replace mode with transaction rollback
• Partial failure handling
• Archive validation (version, structure, missing files)
• Preview generation with conflict detection

Frontend Tests

• Import button visibility and file selection
• Client-side validation (file extension, size limit)
• Multi-step dialog flow (Upload → Preview → Confirm → Progress → Results)
• Responsive design (320px, 768px, 1920px)
• Touch targets >= 44px
• Error handling and user feedback

Quality Checks

• TypeScript compilation (0 errors)
• ESLint (0 errors)

feat: add batch insert operations to repositories (refs #26) ... e6af7ed5d5

Add batchInsert methods to vehicles, fuel-logs, maintenance, and documents repositories. Multi-value INSERT syntax provides 10-100x performance improvement over individual operations for bulk data import.

- vehicles.repository: batchInsert for vehicles
- fuel-logs.repository: batchInsert for fuel logs
- maintenance.repository: batchInsertRecords and batchInsertSchedules
- documents.repository: batchInsert for documents
- All methods support empty array (immediate return) and optional transaction client
- Fix lint error: replace require() with ES6 import in test mock

feat: add archive extraction and validation service (refs #26) ... ffadc48b4f

Implement archive service to extract and validate user data import archives. Validates manifest structure, data files, and ensures archive format compatibility with export feature.

- user-import.types.ts: Type definitions for import feature
- user-import-archive.service.ts: Archive extraction and validation
- Validates manifest version (1.0.0) and required fields
- Validates all data files exist and contain valid JSON
- Temp directory pattern mirrors export (/tmp/user-import-work)
- Cleanup method for archive directories

feat: add import service and API layer (refs #26) ... a35d05f08a

Implements Milestone 3: Backend import service and API with:

Service Layer (user-import.service.ts):
- generatePreview(): extract archive, validate, detect VIN conflicts
- executeMerge(): chunk-based import (100 records/batch), UPDATE existing by VIN, INSERT new via batchInsert
- executeReplace(): transactional DELETE all user data, batchInsert all records
- Conflict detection: VIN duplicates in vehicles
- Error handling: collect errors per record, continue, report in summary
- File handling: copy vehicle images and documents from archive to storage
- Cleanup: delete temp directory in finally block

API Layer:
- POST /api/user/import: multipart upload, mode selection (merge/replace)
- POST /api/user/import/preview: preview without executing import
- Authentication: fastify.authenticate preHandler
- Content-Type validation: application/gzip or application/x-gzip
- Magic byte validation: FileType.fromBuffer verifies tar.gz
- Request validation: Zod schema for mode selection
- Response: ImportResult with success, mode, summary, warnings

Files Created:
- backend/src/features/user-import/domain/user-import.service.ts
- backend/src/features/user-import/api/user-import.controller.ts
- backend/src/features/user-import/api/user-import.routes.ts
- backend/src/features/user-import/api/user-import.validation.ts

Files Updated:
- backend/src/app.ts: register userImportRoutes with /api prefix

Quality:
- Type-check: PASS (0 errors)
- Linting: PASS (0 errors, 470 warnings - all pre-existing)
- Repository pattern: snake_case→camelCase conversion
- User-scoped: all queries filter by user_id
- Transaction boundaries: Replace mode atomic, Merge mode per-batch

fix: prevent vehicle duplication and enforce tier limits in merge mode (refs #26) ... f48a18287b

Critical bug fixes for import merge mode:

1. Vehicle duplication bug (RULE 0 - CRITICAL):
   - Previous: Vehicles without VINs always inserted as new, creating duplicates
   - Fixed: Check by VIN first, then fallback to license plate matching
   - Impact: Prevents duplicate vehicles on repeated imports

2. Vehicle limit bypass (RULE 0 - CRITICAL):
   - Previous: Direct repo.create() bypassed tier-based vehicle limits
   - Fixed: Use VehiclesService.createVehicle() which enforces FOR UPDATE locking and tier checks
   - Impact: Free users properly limited to 1 vehicle, prevents limit violations

Changes:
- Added VehiclesService to import service constructor
- Updated mergeVehicles() to check VIN then license plate for matches
- Replace repo.create() with service.createVehicle() for limit enforcement
- Added VehicleLimitExceededError handling with clear error messages

egullickson added 1 commit 2026-01-12 03:03:33 +00:00

debug: add comprehensive logging to vehicle import merge (refs #26) ... 62b4dc31ab

Added detailed logging to diagnose import merge issues:

- Log vehicle count at merge start
- Log each vehicle being processed with VIN/make/model/year
- Log when existing vehicles are found (by VIN or license plate)
- Log successful vehicle creation with new vehicle ID
- Log errors with full context (userId, VIN, make, model, error message)
- Log merge completion with summary statistics

This will help diagnose why vehicles show as "successfully imported" but don't appear in the UI.

fix: preserve vehicle identity by checking ID first in merge mode (refs #26) ... 28574b0eb4

Critical fix for merge mode vehicle matching logic.

Problem:
- Vehicles with same license plate but no VIN were matched to the same existing vehicle
- Example: 2 vehicles with license plate "TEST-123" both updated the same vehicle
- Result: "Updated: 2" but only 1 vehicle in database, second vehicle overwrites first

Root Cause:
- Matching order was: VIN → license plate
- Both vehicles had no VIN and same license plate
- Both matched the same existing vehicle by license plate

Solution:
- New matching order: ID → VIN → license plate
- Preserves vehicle identity across export/import cycles
- Vehicles exported with IDs will update the same vehicle on re-import
- New vehicles (no matching ID) will be created as new records
- Security check: Verify ID belongs to same user before matching

Benefits:
- Export-modify-import workflow now works correctly
- Vehicles maintain identity across imports
- Users can safely import data with duplicate license plates
- Prevents unintended overwrites
