How to parse EANCOM 2002 messages (DESADV, ORDERS, INVOIC) in TypeScript?

[hello-ediflow]

We're integrating with retail partners who use EANCOM 2002 (GS1 subset of EDIFACT). Messages include DESADV (Despatch Advice), ORDERS, and INVOIC with GLN identifiers and EAN-13 product codes.

Is there a Node.js/TypeScript library that understands EANCOM message structures?

[hello-ediflow]

EDIFlow has a dedicated EANCOM 2002 data package with all 50 GS1 retail message types:

npm install @ediflow/edifact @ediflow/eancom-2002

import {
  EdifactMessageParser,
  EdifactDelimiterDetector,
  EdifactTokenizer,
  EdifactSegmentParser,
} from '@ediflow/edifact';

const parser = new EdifactMessageParser(
  new EdifactDelimiterDetector(),
  new EdifactTokenizer(),
  new EdifactSegmentParser(),
);

const desadv = parser.parse(eancomDesadvString);

console.log(desadv.messageType.value);  // 'DESADV'

// Access NAD segments for GLN identifiers
const parties = desadv.segments.filter(s => s.tag === 'NAD');
for (const party of parties) {
  console.log(`${party.elements[0]?.value}: GLN ${party.elements[1]?.value}`);
  // "BY: GLN 4012345000004"
}

Supported EANCOM message types include: DESADV, ORDERS, ORDRSP, INVOIC, PRICAT, SLSRPT, RECADV, INVRPT, MSCONS, and 40+ more.
