Quick Examples

Code 11 Example

const symbology = require('symbology')

symbology
  .createStream({
    symbology: symbology.Barcode.CODE128
  }, '8765432164')
  .then((data) => {
    console.log('Result: ', data)
  })

This will log:

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

And the base64 PNG generated will look like:

MaxiCode Example

symbology
  .createFile({
    symbology: Symbology.Barcode.MAXICODE,
    option1: 2,
    primary: '999999999840012',
    fileName: 'maxiCodeExample.svg'
  }, 'Secondary Message Here')
  .then((data) => {
    console.log('Result: ', data)
  })

This creates maxiCodeExample.svg which looks like:

USPS Example

symbology
  .createFile({
    symbology: Symbology.Barcode.ONECODE
    fileName: 'uspsExample.eps'
  }, '01234567094987654321-01234')
  .then((data) => {
    console.log('Result: ', data)
  })

This creates uspsExample.eps which looks like:
