getSvgDataURI

Use dataURI

let barcode = cnfBarcode("Hi!").getSvgDataURI();

Result:

data:image/svg+xml;utf8,........

Examples for browsers:

Simple example:

let barcode = cnfBarcode("Hi!").getSvg();
// or use DataURL
let barcode = cnfBarcode("Hi!").getSvgDataURI();

Example with options:

cnfBarcode("1234", {
  format: "pharmacode",
  lineColor: "#f4a460",
  width:4,
  height:40,
  displayValue: false
});

Result:

More advanced use case:

let barcode = cnfBarcode().options({font: "OCR-B"}) // Will affect all barcodes
      .EAN13("1234567890128", {fontSize: 18, textMargin: 0})
      .blank(20) // Create space between the barcodes
      .EAN5("12345", {height: 85, textPosition: "top", fontSize: 16, marginTop: 15})
      .render().getSvg();

Result:
