rn-barcode-renderer: Render Barcodes and QR Codes in Expo and React Native
I'm excited to introduce my new npm package, rn-barcode-renderer, designed to simplify rendering barcodes and QR codes in Expo and React Native applications. This package leverages the power of React Native Skia to provide efficient and high-quality barcode and QR code generation.
Why I Created rn-barcode-renderer
In the world of mobile development, generating barcodes and QR codes can be a bit cumbersome, especially when you want seamless integration with your existing Expo or React Native projects. Existing solutions often required a lot of boilerplate code or didn't offer the performance I needed. To solve this problem, I decided to build a straightforward yet powerful library.
Key Features
- Ease of Use: Integrate barcode and QR code rendering with minimal setup.
- Performance: Optimized for high performance using React Native Skia.
- Customization: Easily customizabasdfasdle to fit the design needs of your application.
- Support for Multiple Barcode Formats: Supports various barcode types including Code128, Code39, EAN, UPC, ITF, MSI, and more.
Getting Started
Start by installing the peer dependencies of rn-barcode-renderer:
bash
npm install @shopify/react-native-skia
Then install rn-barcode-renderer:
bash
npm install rn-barcode-renderer
Then, import and use it in your Expo or React Native project:
javascript
import { BarcodeView, QrCode } from 'rn-barcode-renderer'; const App = () => ( <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}> <BarcodeView value="123456789" format="CODE128" maxWidth={200} height={100} /> <QrCode value="<https://example.com>" size={200} /> </View> );
Customization Options
Barcode component
The BarcodeView component provides various customization options to tailor the appearance of your barcodes:
- value: The value of the barcode.
- format: The format of the barcode (e.g., "CODE128", "CODE39", "EAN13", etc.).
- barWidth: The width of each individual bar (default: 2).
- height: The height of the barcode (default: 100).
- color: The color of the barcode (default: "#000000").
- bgColor: The background color of the barcode container (default: "#ffffff").
Example:
javascript
<BarcodeView value="123456789" format="CODE128" barWidth={2} height={100} color="black" bgColor="white" />
These are some of the options. Check the repository for more customization options.
QRCode Component
The QrCode component also offers customization options to fit your design needs:
- value: The value of the QR code.
- size: The size of the QR code (default: 100).
- color: The color of the QR code (default: "#000000").
- bgColor: The background color of the QR code (default: "#ffffff").
Example:
