react-use-barcode

A React hook for generating barcode images.

Installation

npm install react-use-barcode

Usage

To use the useBarcode hook, simply import it into your component and call it with the value and options parameters:

import { useBarcode, BarcodeOptions } from 'react-use-barcode';

const MyComponent = () => {
  const options: BarcodeOptions = { height: 50, width: 3 };
  const barcode = useBarcode('123456789', options);

  return (
    <img src={barcode} alt="Barcode" />
  );
};

The useBarcode hook takes two parameters:

value: the value to be encoded as a barcode (required).

options: an object containing options for the barcode generation (optional) The options parameter is an object with properties:

• height: the height of the barcode image.
• width: the width of the barcode image.
• Any option passed to JSBarcode

The useBarcode hook returns a base64-encoded string representing the barcode image, or undefined if the image has not yet been generated.
