@point-of-sale/

A set of JavaScript libraries for building point-of-sale applications. From receipt printers to barcode scanners, we've got you covered.

Print receipts from the browser or any other JavaScript runtime
Scan barcodes using any common scanner, or use your webcam
Field tested on dozens of actual printers and barcode scanners

Create a receipt using a simple API that describes what you want to show on your receipt. You can add text, tables, barcodes and QR codes. And if you want you can even use Markdown for text style or Receiptline for layout. Then encode your receipt into ESC/POS or StarPRNT printer languages.

Pick from a number of different printer drivers that fit your situation and your hardware. Use WebUSB, WebSerial or WebBluetooth direct from the browser, or use vendor SDKs from Capacitor. You can even use the already installed system printer drivers from Node or Electron for a seamless printing experience.
