Implementing Syncfusion React Barcode

When to Use This Skill

Use this skill when you need to:

• Generate barcodes (Code39, Code128, Code11, Code32, Code93, Codabar) in React
• Create QR codes for URLs, contact info, or product identification
• Generate Data Matrix codes for labels, tracking, or inventory
• Customize barcode appearance (size, color, text display)
• Export barcodes as images (JPG, PNG) or base64 strings
• Integrate barcode generation into forms, reports, or applications

Library Overview: Three Generator Types

Syncfusion React Barcode provides three main components:

1. BarcodeGeneratorComponent - Traditional 1D barcodes (Code39, Code128, etc.)

- Character encoding varies by type - Ideal for: Product codes, inventory, retail - Readability: High, works with basic scanners

1. QRCodeGeneratorComponent - 2D Quick Response codes

- Versions 1-40 with automatic scaling - Ideal for: URLs, contact info, product links, advertising - Capacity: Up to thousands of characters

1. DataMatrixGeneratorComponent - 2D Data Matrix codes

- Square/rectangular format, compact size - Ideal for: Labels, parts tracking, aerospace/automotive - Capacity: Alphanumeric data, efficient encoding

Quick Start Examples

Code39 Barcode

import React from 'react';
import { BarcodeGeneratorComponent } from '@syncfusion/ej2-react-barcode-generator';

export default function App() {
  return (
    <BarcodeGeneratorComponent
      id="barcode"
      type="Code39"
      value="SYNCFUSION"
      width="200px"
      height="150px"
    />
  );
}

QR Code

import React from 'react';
import { QRCodeGeneratorComponent } from '@syncfusion/ej2-react-barcode-generator';

export default function App() {
  return (
    <QRCodeGeneratorComponent
      id="qrcode"
      value="https://www.syncfusion.com"
      width="200px"
      height="200px"
    />
  );
}

Data Matrix

import React from 'react';
import { DataMatrixGeneratorComponent } from '@syncfusion/ej2-react-barcode-generator';

export default function App() {
  return (
    <DataMatrixGeneratorComponent
      id="datamatrix"
      value="Syncfusion"
      width="200px"
      height="200px"
    />
  );
}

Common Patterns

Pattern 1: Dynamic Value Generation

const [barcodeValue, setBarcodeValue] = React.useState('DEFAULT123');

<BarcodeGeneratorComponent
  type="Code128"
  value={barcodeValue}
  width="200px"
  height="150px"
/>

Pattern 2: Export on Button Click

const barcodeRef = React.useRef();

const handleExport = () => {
  barcodeRef.current.exportImage('barcode', 'PNG');
};

<div>
  <BarcodeGeneratorComponent
    ref={barcodeRef}
    type="Code39"
    value="SYNC123"
    width="200px"
    height="150px"
  />
  <button onClick={handleExport}>Download Barcode</button>
</div>

Pattern 3: Styled Container

<div style={{ padding: '20px', border: '1px solid #ddd' }}>
  <QRCodeGeneratorComponent
    value="https://example.com"
    width="250px"
    height="250px"
    foreColor="#333"
    backgroundColor="#fff"
  />
</div>

Key Props

Common Use Cases

1. Retail & Inventory: Code128 barcodes for products and SKUs
