Installation

npm install @tecuity/barcode-generator

or

yarn add @tecuity/barcode-generator

Usage

For a default usage, just import and call the generator with a string like this:

import generateBarcode from '@tecuity/barcode-generator'

const barcode = generateBarcode("1234567")

And that's it! By default the generator will return a barcode as a base64-encoded data url. Ready to pop into the src attribute of an img element.

For further customization, you can pass an options object as the second parameter of the function like so:

import generateBarcode from '@tecuity/barcode-generator'

const barcode = generateBarcode("1234567", {raw: true, spacing: 10})

API Reference:

Key	Type	Default	Description
spacing	int || float	5	The spacing between characters, relative to the viewBox of the resulting SVG.
raw	boolean	false	Returns the barcode as a raw SVG string rather than a base64 data-url.
height	int || float	172.89	The viewBox height of the resulting SVG.
