# Architecture

|

Barcode Tools is a static React/Vite application wrapped in the shared Toolbox shell. `barcode/generate.ts` validates options, delegates encoding to the browser build of `bwip-js`, rejects active or linked constructs in the generated SVG string, and previews it through a revocable blob URL. It also parses the bounded two-column batch format and creates deterministic SVG ZIPs with `fflate`.

`barcode/payloads.ts` escapes structured QR fields and validates GTIN check digits. The decode workspace lazy-loads ZXing only after a file or camera action. Image files are passed through a revocable object URL; camera acquisition is explicit and its controls are stopped on request or unmount. Decoded values are rendered as text and never navigated.

Version 0.1 does not create an application worker or persist input. The camera requires a secure context but not a top-level browsing context. Relative entry and asset URLs keep the build relocatable below a nested portal path.
