Codify

A Node.js module that generates barcode images. Supports 50+ different 1D or 2D symbologies in png, eps, or svg formats.

We have based this package on symbology and are contributing to the code from them.

Introduction

This Node.js module will allow you to generate over 50+ different types of 1D or 2D symbologies, including barcodes for books, grocery, shipping carriers, healthcare, and international codes.

It can create a PNG, SVG, or EPS image file, or return a string containing SVG, PostScript, or base64-encoded PNG data.

Major changes made to this package regards of origin are:

• fixed version of zint packed up with the package
• fixed building zint

Quick Examples

Code 11 Example

import { SymbologyType, createStream } from 'symbology'

(async () => {
  const { data } = await createStream({
    symbology: SymbologyType.CODE11
  }, '8765432164')

  console.log('Result: ', data)
})()

This will log:

{
  "data": "data:image/png+data;base64,PHN [...] eFd==",
  "message": "Symbology successfully created.",
  "code": 0
}

And the base64 PNG generated will look like:

MaxiCode Example

import { SymbologyType, createFile } from 'symbology'

(async () => {
  const { data } = await createFile({
    symbology: SymbologyType.MAXICODE,
    option1: 2,
    primary: '999999999840012',
    fileName: 'maxiCodeExample.svg'
    showHumanReadableText: false,
  }, 'Secondary Message Here')

  console.log('Result: ', data)
})()

This creates maxiCodeExample.svg which looks like:

USPS Example

import { SymbologyType, createFile } from 'symbology'

(async () => {
  const { data } = await createFile({
    symbology: SymbologyType.ONECODE
    fileName: 'uspsExample.eps'
  }, '01234567094987654321-01234')

  console.log('Result: ', data)
})()

This creates uspsExample.eps which looks like:
