Inventory UI S3

This project provides a React frontend and a Go backend that store and retrieve table data from an S3 compatible storage (MinIO). Everything is orchestrated using Docker Compose.

Usage

1. Copy .env.example to .env and adjust credentials if needed.
2. Ensure web/frontend/.env contains REACT_APP_API_URL=http://localhost:8080/api so the browser can reach the backend.
3. Run docker-compose up --build to start the backend, frontend and MinIO services.
4. Access the frontend at http://localhost:3000, the backend at http://localhost:8080 and the MinIO console at http://localhost:9001 (default credentials are from .env).

The backend exposes several endpoints under /api:

• GET /api/tabs – list directories in the bucket which become tabs in the UI
• GET /api/table/{tab} – fetch the latest JSON or Excel file for the given tab
• PUT /api/table/{tab} – upload table data back as <tab>.json

If the configured bucket does not exist, it is created on startup. The backend exits with an error log if it cannot connect to the S3 service.
