Food Scanner App Overview
This page summarizes what the app does, how it is built, and how the major pieces fit together for development, deployment, and review.
Frontend stack
Next.js static export, React, Cognito auth helpers, and a responsive card-based interface with inline image compression.
Backend stack
AWS Lambda, API Gateway, Cognito JWT verification, DynamoDB scan storage, and OpenAI-powered analysis with fallback logic.
Key endpoints
/health, /config, /analyze, and protected /scans routes for loading and saving account history.
How to use it
Sign in with Cognito to sync scan history across devices. If you stay signed out, scans remain on this device only. The app will still analyze photos and show useful nutrition guidance either way.
