Barcode Validator

A tiny JavaScript library for validating barcodes.

Supported symbologies: EAN-13, EAN-8, UPC-A, and UPC-E. For more information on the validation algorithm, see official GS1 guide on calculating valid barcode check digits.

Usage

First, install barcode-validator using npm:

npm i barcode-validator

Then, import the package into your module like so:

import validbarcode from "barcode-validator";
// or const validbarcode = require("barcode-validator");

Pass it a barcode (string or number) for validation and get back a boolean.

validbarcode("6151100036810"); // true
validbarcode(87162318); // true
validbarcode(972660036810); // false
