Installation troubleshooting

This app is dependent on canvas and zBar.wasm. On some machines like M1 Mac you need to compile canvas. To do so please check this LINK. If you have problem with running zBar check for Node.JS version you are running.

⚠️ I recommend using Node.JS 16 LTS.

How to use it

const bpbr = require("bulk-pdf-barcode-reader");

async function main() {
    // First input is .pdf file location
    // Second input is viewport scale - bigger the scale = better reading resolution
    const result = await bpbr("./file.pdf", 1.0);
    console.log(result);
}

main();
