A simple barcode scanner with support for shift modifier key.

This package is specifically written for the Rakinda RD4500R USB barcode scanner, but can be used with other 'wedge' usb barcodescanners

Note: Since a wedge scanner is seen as a keyboard on the OS you need elevated rights on macOS or Linux to use the package. You can also specify a udev rule in Linux to own the scanner.

Use npm to install the package

npm install @isirthijs/barcode-scanner

create a new instance of a scanner by passing the productID/vendorID or the path of the scanner into the constructor

const UsbScanner = require('@isirthijs/barcode-scanner'); // Using vendorID and ProductID const options = { vendorID: 1234, productID: 5678 } // Using path const options = { path: 'IOService:/AppleACPI....' } const scanner = new UsbScanner(options)

scanner.on('data', (data) => { /// your code console.log(data); }); scanner.startScanning()

• Returns the devices connected to the computer.

• Creates and opens a new scanner using the options
  • vendorID - number - the vendorID of the device
  • productID - number - the productID of the device
  • path - string the path of the devices
  • vCardString - boolean - default: true - If true returns vCards as one string, instead of separate strings.
  • vCardSeperator string - default: '|' - If vCard string is true, this will be used as separation between the strings.

• Starts listening for barcodes

• Stops listening for barcodes and closes the HID device.

• listen for the data event to receive the barcode
• data - a string containing the barcode as readable text from the scanner
