Skaf's Barcode Formatter

Introduction

• Lots of entered barcodes in the Skaf's system were entered short handed
  • for lots of GTIN-12 barcodes, instead of (0)3120044499(8), it was just 3120044499
    • leading zero and check
  • GTIN-8 barcodes are stored as fully expanded GTIN-12 barcodes
    • this is a problem as barcode checker apps often DO NOT expand GTIN-8 to GTIN-12 barcodes for you
• This node module will allow easy conversion of these barcodes ahead of time

Installation

$> npm i SkafsBarcodeFormatter

Usage

/**
where upc is string, and return value is string
*/
import {GtinHandler} from "skafs-barcode-formatter";
const formattedUPC = GtinHandler.handleUPC(upc);

• this function will take a gtin12 eligible upc entered in the breakpoint system, and then convert that to what the real life barcode would be
• it will:
  • expand upcs with missing leading zeroes and or missing check digits
  • minify gtin8 eligible barcodes (usually length 10 in breakpoint system)

Notes

• for case of 11 length upc
  • traditionally, when entered into the breakpoint system by Skaf's, we would write it as an integer
  • this means it is much more likely to be missing the check digit than the leading zero
  • therefore, handleUPC will first try to create a checkdigit for these upcs
  • if that fails, it will add a leading zero
