qrbit

Qrbit is a high-performance QR code generation library designed for Node.js environments. It leverages Rust as a native Node.js addon to achieve maximum speed and efficiency, eliminating the need for external modules like `node-canvas` for image processing. The library supports generating QR codes with embedded logos, offering configurable error correction levels (L, M, Q, H), custom background and foreground colors, adjustable sizes, and margins. Key features include: * **Performance**: Utilizes Rust for fast QR code generation and image conversion. * **Logo Embedding**: Allows embedding custom logos directly into QR codes with options for size ratio, background color, and padding. * **Multiple Formats**: Outputs QR codes as SVG strings or files, and as PNG, JPEG, or WebP buffers or files. * **Cross-platform**: Compatible with iOS, Windows, Linux, and macOS. * **Customization**: Provides extensive options for visual appearance, including colors, size, margin, and error correction level. * **Caching**: Includes built-in caching mechanisms for improved performance on repeated generations. Qrbit provides a straightforward API for creating QR code instances and generating various outputs. It also includes static utility methods for converting SVG content to other image formats. Benchmarks indicate superior performance compared to other JavaScript-based QR code libraries, especially for image generation and logo embedding. The project is actively maintained and well-tested, making it a robust solution for integrating QR code generation into Node.js applications.
