PTW UDI

Generates an unique device identification as specified by HIBC UDI (ANSI/HIBC 2.5 - 2015). You can find more information about the specification of the unique device identification on the HIBC website.

This library is very small (~6KB minified, no external dependencies) and its sole purpose is to generate a HIBC-conform data structure that uniquely identifies a product. It will automatically create a string with the correct order of information and check characters. The string can then be used by your favorite barcode generating library to generate a Bar-/QR-Code based on the generated string.

Install

$ npm install ptw-udi --save

Note: If you just want to embed the library in your website, use the file found in dist/udi.min.js.

Usage

The public API consists of 3 methods to create different types of data structures (primary, secondary and combined) and one method to transform the created data structure to a string that can be placed below the barcode.

Below are some examples that show how to create unique device identifications with ptw-udi. For an complete overview of the API, please check out the included declarations files lib/udi.d.ts. If you're using Typescript, you also can import PrimaryDataStructureConfig and SecondaryDataStructureConfig for additional help with the inevitable large method signature.

Primary Data Structure

import { createPrimaryDataStructure } from 'ptw-udi';

const udi = createPrimaryDataStructure({
    lic: 'BLUE',
    pcn: 'UNICORN',
    unitOfMeasure: 7
});
// udi = "+BLUEUNICORN7N"

Secondary Data Structure

import { createSecondaryDataStructure, DateFormat, QuantityFormat } from 'ptw-udi';

const lic = 'A123';
const pcn = 'BJC5D6E71G';
const unitOfMeasure = 1;

const lot = '3C001';
const sn = '0001';

let udi = createSecondaryDataStructure({
    lic, pcn, unitOfMeasure,
    lot, sn,
    expDate: {
        format: DateFormat.MMDDYY,
        value: '092805'
    },
    manufactureDate: '20000101'
});
// udi = "+$$20928053C001/S0001/16D20000101XQ"

udi = createSecondaryDataStructure({
    lic, pcn, unitOfMeasure,
    lot,
    quantity: {
        format: QuantityFormat.QQQQQ,
        value: '12345'
    },
    expDate: {
        format: DateFormat.YYYYMMDD,
        value: '20200101'
    },
    manufactureDate: '20160101'
})
// udi = "+$$91234573C001/16D20160101/14D20200101XX"

Combined Data Structure

import { createCombinedDataStructure, DateFormat } from 'ptw-udi';

const lic = 'A123';
const pcn = 'BJC5D6E71G';
const unitOfMeasure = 1;

const lot = '3C001';
const sn = '0001';

const udi = createCombinedDataStructure({
    lic, pcn, unitOfMeasure,
    lot, sn,
    expDate: {
        format: DateFormat.YYYYMMDD,
        value: '20200101'
    },
    manufactureDate: '20160101'
});
// udi = "+A123BJC5D6E71G1/$$73C001/S0001/16D20160101/14D20200101Y"

Errors

ptw-udi will throw errors if the input does not adhere the HIBC specification. For instance, if you pass a quantity to the library that does not has the required length, an Error will be thrown. We tried to make the errors helpful, so that you know how to fix the problematic input.

A quantity with the format QQQQQ and value of '100' will generate the following error message:

$ Expected "quantity.value" to be an numeric value with length of "5", but was "100".
