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());
