Package Exports

ean-epc
ean-epc/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ean-epc) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

epc-tds

EPC Tag Data Standard encoding and decoding library, written in javascript (Node.JS and Frontend)

Simple, very fast and easy to use ;)

Usage

Automatic decoding of any standard (SGTIN-96, SGTIN-198, SSCC-96, SGLN-96, GID, GRAI, GSRN, ...)

const epcTds = require('epc-tds');

var epc = epcTds.valueOf("3074257BF7194E4000001A85"); // SGTIN-96
console.log("Id URI : " + epc.toIdURI());
console.log("Tag URI: " + epc.toTagURI());
console.log("Barcode: " + epc.toBarcode()); // sgtin
console.log("Serial : " + epc.getSerial());

epc = epcTds.valueOf("3178E61C883950F59A000000"); // SSCC-96
console.log("Id URI : " + epc.toIdURI());
console.log("Tag URI: " + epc.toTagURI());
console.log("Barcode: " + epc.toBarcode()); // sscc
console.log("Serial : " + epc.getSerialReference());

epc = epcTds.valueOf("377A6BB0C1BDA6D9B664D1AB266D1AB266D1AB266D00"); // GRAI-170
console.log("Id URI : " + epc.toIdURI());
console.log("Tag URI: " + epc.toTagURI());
console.log("Barcode: " + epc.toBarcode()); // grai
console.log("Serial : " + epc.getSerial());

Decode Hex EPC

const epcTds = require('epc-tds');

// Decode from Hex EPC
let epc = tds.valueOf("3074257BF7194E4000001A85"); // sgtin-96

// Acces to epc properties
console.log("Type: "          + epc.getType()); // TDS ID
console.log("Filter: "        + epc.getFilter()); // filter index
console.log("Partition: "     + epc.getPartition()); // partition index
console.log("CompanyPrefix: " + epc.getCompanyPrefix());
console.log("ItemReference: " + epc.getItemReference());
console.log("GTIN(EAN): "     + epc.getGtin()); // ean
console.log("HexEPC: "        + epc.toHexString()); // HEX EPC
console.log("Tag URI: "       + epc.toTagURI());

// Decode from Hex Tag URI
epc = epcTds.fromTagURI('urn:epc:tag:sgtin-96:3.0614141.812345.6789');
console.log("HexEPC: "  + epc.toHexString()); // HEX EPC
console.log("Tag URI: " + epc.toTagURI());

Encode Hex EPC

const epcTds = require('epc-tds');

// e.g. 1: EAN + Serial
let epc1 = new epcTds.Sgtin96().setFilter(3)
                            .setPartition(5)
                            .setGtin("00001234523457")
                            .setSerial(1823342345);

console.log("HexEPC: "  + epc1.toHexString()); // HEX EPC
console.log("Tag URI: " + epc1.toTagURI());
       
// e.g. 2: (companyPrefix + ItemReference) + Serial
let epc2 = new epcTds.Sgtin96().setFilter(3)
                            .setPartition(5)
                            .setCompanyPrefix(78952)
                            .setItemReference(44235)
                            .setSerial(1010011010);
                        
console.log("HexEPC: "  + epc2.toHexString()); // HEX EPC
console.log("Tag URI: " + epc2.toTagURI());
