Failed to load or decode Blob.

[雪狐]

I created a minimum instance like in the example to run.

I use esbuild-register run the code

then it throws DOMException [InvalidStateError]: Failed to execute 'detect' on 'BarcodeDetector': Failed to load or decode Blob.

// package.json

I don't think this package will fully work on nodejs because it relies on some DOM APIs. This package is intended for browsers.

However this issue is caused by some mistake I made here (Reference Errors) and it will be fixed soon. Thanks for raising this issue.

Hello, v2.1.3 fixed this error message. But as I said this package is intended for browsers so it still won't work in node because DOMRectReadOnly is a DOM API and it is specified in the spec https://wicg.github.io/shape-detection-api/#detectedbarcode-section.

If you don't need a spec-compliant barcode detector and want a solution in node, check out zxing-wasm

I have already tried zxing-wasm before, but there will be errors when I run it after building it, tsconfig like above

error like:

[ERR_REQUIRE_ESM]: require() of ES Module D:\path\to\node_modules\zxing-wasm\dist\full\index.js from D:\path\to\barcodeDecoder\lib\index.js not supported.

Instead change the require of D:\path\to\node_modules\zxing-wasm\dist\full\index.js in D:\path\to\barcodeDecoder\lib\index.js to a dynamic 'import("zxing-wasm")' which is available in all CommonJS modules

then I tried dynamic import, but still made an error.
