Installation

npm install @tecuity/barcode-generator

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})
