API Reference

generateSVG(options)

Generates a QR code as an SVG string.

type Options = {
  value: string; // Content to encode
  size?: number; // Size in pixels (default: 128)
  level?: "L" | "M" | "Q" | "H"; // Error correction level (default: "L")
  bgColor?: string; // Background color (default: "#FFFFFF")
  fgColor?: string; // Foreground color (default: "#000000")
  margin?: number; // Margin around QR code (default: 2)
  imageSettings?: {
    src: string; // URL of the image to embed
    height?: number; // Image height
    width?: number; // Image width
    x?: number; // X position
    y?: number; // Y position
    excavate?: boolean; // Whether to clear QR code modules under the image
  };
  // Any additional SVG attributes are passed through to the root SVG element
};

Error Correction Levels

• L: Low (7% of data can be restored)
• M: Medium (15% of data can be restored)
• Q: Quartile (25% of data can be restored)
• H: High (30% of data can be restored)

Note: When using imageSettings with excavate: true, the error correction level will automatically be increased to at least 'Q' to ensure better scannability.
