Browser

javascriptBarcodeReader({
  /* Image ID || HTML5 Image || HTML5 Canvas || HTML5 Canvas ImageData || Image URL */
  image: source,
  barcode: 'code-2of5',
  // barcodeType: 'industrial',
  options: {
    // useAdaptiveThreshold: true // for images with sahded portions
    // singlePass: true
  }
})
  .then(code => {
    console.log(code)
  })
  .catch(err => {
    console.log(err)
  })

Note

This script does not implement logic to locate/rotate barcode in the given image.
Make sure the barcode image is the only thing in the image. Otherwise this script will most probably fail.
