## Overview

Barcode Generator is a localized web tool for configuring and generating one or many barcodes, previewing them, and downloading or sharing results. The main workflow runs through the locale-specific barcode page and generator UI; the generator parses input and renders it using barcode libraries, while context stores user settings locally. The README documents multiple formats and image exports. Some component internals were not sampled, so links for import, sharing, and export reflect their evident roles and documented capabilities rather than detailed call chains.

Main entry points: [`src/components/barcode-generator/BarcodeContext.tsx`](https://github.com/leonzeng919/barcode-generator/blob/main/src/components/barcode-generator/BarcodeContext.tsx) (Generator state), [`src/components/barcode-generator/useBarcodeGenerator.tsx`](https://github.com/leonzeng919/barcode-generator/blob/main/src/components/barcode-generator/useBarcodeGenerator.tsx) (Barcode renderer), [`src/app/api/barcode/[code]/[data]/route.ts`](https://github.com/leonzeng919/barcode-generator/blob/main/src/app/api/barcode/%5Bcode%5D/%5Bdata%5D/route.ts) (SVG endpoint), [`src/components/barcode-generator/index.tsx`](https://github.com/leonzeng919/barcode-generator/blob/main/src/components/barcode-generator/index.tsx) (Generator interface)
