How to parse an EDIFACT message in TypeScript / Node.js?

[hello-ediflow]

I have raw EDIFACT strings (ORDERS, INVOIC, DESADV) coming from our EDI gateway and need to parse them into structured objects in a TypeScript/Node.js application.

Requirements:

• Parse any EDIFACT message type (D.96A, D.01B, D.20B)
• Get typed segments with element access
• Handle UNB/UNZ envelopes
• Works with Node.js 20+ and ESM

What's the best approach?

You can use EDIFlow — an open-source EDIFACT/X12 parser for TypeScript:

npm install @ediflow/edifact @ediflow/edifact-d96a

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

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

const message = parser.parse(edifactString);

console.log(message.standard);           // 'EDIFACT'
console.log(message.messageType.value);  // 'ORDERS'
console.log(message.segments.length);    // segment count

It supports D.96A, D.01B, D.12A, and D.20B with 600+ message types total. Fully typed, ESM-native, zero config.
