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 🙏

JsBarcode is a barcode generator written in JavaScript. It supports multiple barcode formats and works in browsers and with Node.js. It has no dependencies when it is used for the web but works with jQuery if you are into that.

Supported barcodes:

Examples for browsers:

First create a canvas (or image)

<svg id="barcode"></svg>
<!-- or -->
<canvas id="barcode"></canvas>
<!-- or -->
<img id="barcode"/>

Simple example:

JsBarcode("#barcode", "Hi!");
// or with jQuery
$("#barcode").JsBarcode("Hi!");
Result:

Result

Example with options:

JsBarcode("#barcode", "1234", {
  format: "pharmacode",
  lineColor: "#0aa",
  width:4,
  height:40,
  displayValue: false
});
Result:

Result

More advanced use case:

JsBarcode("#barcode")
  .options({font: "OCR-B"}) // Will affect all barcodes
  .EAN13("1234567890128", {fontSize: 18, textMargin: 0})
  .blank(20) // Create space between the barcodes
  .EAN5("12345", {height: 85, textPosition: "top", fontSize: 16, marginTop: 15})
  .render();
Result:

Result

Or define the value and options in the HTML element:

Use any jsbarcode-* or data-* as attributes where * is any option.

<svg class="barcode"
  jsbarcode-format="upc"
  jsbarcode-value="123456789012"
  jsbarcode-textmargin="0"
  jsbarcode-fontoptions="bold">
</svg>

And then initialize it with:

JsBarcode(".barcode").init();
Result:

Result

Retrieve the barcode values so you can render it any way you'd like

Pass in an object which will be filled with data.

const data = {};
JsBarcode(data, 'text', {...options});

data will be filled with a encodings property which has all the needed values. See wiki for an example of what data looks like.

Setup for browsers:

Step 1:

Download or get the CDN link to the script:

| Name | Supported barcodes | Size (gzip) | CDN / Download | |------|--------------------|:-----------:|---------------:| | All | All the barcodes! | 10.1 kB | JsBarcode.all.min.js | | CODE128 | CODE128 (auto and force mode) | 6.2 kB | JsBarcode.code128.min.js | | CODE39 | CODE39 | 5.1 kB | JsBarcode.code39.min.js | | EAN / UPC | EAN-13, EAN-8, EAN-5, EAN-2, UPC (A) | 6.6 kB | JsBarcode.ean-upc.min.js | | ITF | ITF, ITF-14 | 5 kB | JsBarcode.itf.min.js | | MSI | MSI, MSI10, MSI11, MSI1010, MSI1110 | 5 kB | JsBarcode.msi.min.js | | Pharmacode | Pharmacode | 4.7 kB | JsBarcode.pharmacode.min.js | | Codabar | Codabar | 4.9 kB | JsBarcode.codabar.min.js |

Step 2:

Include the script in your code:

<script src="JsBarcode.all.min.js"></script>

Step 3:

You are done! Go generate some barcodes :smile:

Bower and npm:

You can also use Bower or npm to install and manage the library.

bower install jsbarcode --save
npm install jsbarcode --save

Node.js:

With canvas:

var JsBarcode = require('jsbarcode');

// Canvas v1
var Canvas = require("canvas");
// Canvas v2
var { createCanvas } = require("canvas");

// Canvas v1
var canvas = new Canvas();
// Canvas v2
var canvas = createCanvas();

JsBarcode(canvas, "Hello");

// Do what you want with the canvas
// See https://github.com/Automattic/node-canvas for more information

With svg:

const { DOMImplementation, XMLSerializer } = require('xmldom');
const xmlSerializer = new XMLSerializer();
const document = new DOMImplementation().createDocument('http://www.w3.org/1999/xhtml', 'html', null);
const svgNode = document.createElementNS('http://www.w3.org/2000/svg', 'svg');

JsBarcode(svgNode, 'test', {
    xmlDocument: document,
});

const svgText = xmlSerializer.serializeToString(svgNode);

Options:

For information about how to use the options, see the wiki page.

| Option | Default value | Type | |--------|---------------|------| | format | "auto" (CODE128) | String | | width | 2 | Number | | height | 100 | Number | | displayValue | true | Boolean | | text | undefined | String | | fontOptions | "" | String | | font | "monospace" | String | | textAlign | "center" | String | | textPosition | "bottom" | String | | textMargin | 2 | Number | | fontSize | 20 | Number | | background | "#ffffff" | String (CSS color) | | lineColor | "#000000" | String (CSS color) | | margin | 10 | Number | | marginTop | undefined | Number | | marginBottom | undefined | Number | | marginLeft | undefined | Number | | marginRight | undefined | Number | | valid | function(valid){} | Function |
