Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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
