Summary by Sourcery

Refactor and improve the ingredients classification process with enhanced error handling, worker-based processing, and dependency updates

New Features:

• Added a worker-based approach for ingredient classification to improve performance
• Implemented fallback mechanism for translation failures
• Added concurrency scripts for development workflows

Enhancements:

• Improved error handling in translation process
• Moved sophisticated ingredient matching to a separate worker thread
• Updated project dependencies to latest versions
• Simplified translation error management

CI:

• Added concurrently script for running multiple development checks
• Improved lint and test script integration

Tests:

• Updated unit tests to reflect new error handling behavior
• Added more robust test scenarios for translation failures

Chores:

• Updated package.json scripts
• Upgraded NestJS and related dependencies
• Cleaned up OpenAPI specification
• Updated Dockerfile to use corepack

---

Note

Adds Redis-backed caching and rate limiting, moves ingredient classification to a worker with translation fallback, and caches product data across sources with input validation and updated health/docs.

• Platform:
  • Redis Integration: Add RedisModule with RedisService, CacheService, and config (REDIS_* env). Use cache keys and thundering-herd locks.
  • Rate Limiting: New RedisRateLimiterMiddleware with in-memory fallback; applied globally (excludes health).
  • Health: Add Redis health indicator to /health.
• Ingredients:
  • V1 Worker: Offload classification to ingredient.worker (worker_threads).
  • Translation: Cache DeepL responses; on failure, proceed with untranslated input; adjust tests accordingly.
• Product:
  • Caching & Fetch: Cache grade, OpenFoodFacts, PETA, and OpenEANDB responses; parallelize fetch; add barcode validation; update tests.
• API Docs:
  • Update OpenAPI: improved v1 ingredients 200 description, add local server, health examples; minor tag tweaks.
• Ops/Build:
  • Docker: enable corepack.
  • Env: add REDIS_HOST/PORT/PASSWORD.
  • Scripts: add process:all, check.
• Dependencies:
  • Bump NestJS/JS libs; add redis, rate-limiter-flexible, concurrently, etc.
