node-hl7-encoder

A very simple JSON to hl7 2.x encoder

Install

npm i hl7-encoder

Example

var encoder = require('hl7-encoder');

var message = {
  MSH:{
    _2:'COMPANY',
    _3:'APP',
    _5:'0001',
    _8:'ORU',
    _10:'P',
    _11:'2.3'
    },
  PID:{
    _4: 30006108
    },
  ORC: {
    _1:'DT',
    _3:4712,
    _5:'CM',
    _10:560200,
    _11:214716,
    _16:600022554711,
    _18:['APP_IMAGE','001'],
    _19:'Test Image'
    },
  OBR:{}
};

var encodedMessage = encoder.encode(message);
console.log(encodedMessage);

Encoded message will then be:

MSH|^~\\&|COMPANY|APP||0001|||ORU||P|2.3
PID||||30006108
ORC|DT||4712||CM|||||560200|214716|||||600022554711||APP_IMAGE^001|Test Image
