How I Built a Fast, Offline-First Gluten Detection PWA Using Web OCR & Open Food Facts

Описание и применение

Приложение Glutensa позволяет быстро и автономно определять наличие глютена в продуктах, используя сканирование штрихкода и OCR, с кэшированием данных и резервным запросом к Open Food Facts.

Задача

Consumers with gluten restrictions need instant, reliable ingredient information at the grocery store, but existing apps are slow or heavy.

Результат

The app delivers fast, offline-first gluten detection with a local cache and seamless API fallback, improving user experience for dietary restrictions.

Рабочий процесс

• Scan product barcode or capture label image
• Check local cached dataset for product info
• If not found, query Open Food Facts API
• Parse returned data and display gluten status
• Cache result locally for future use

Доказательства

We first check an optimized local/cached dataset. If no match is found, the app seamlessly falls back to querying the Open Food Facts API
