Forked from https://github.com/amida-tech/mllp because it needed to get issues fixed, namely:

• Create a clone of the input data array prior to swapping elements

HL7's MLLP (Minimum Lower Layer Protocol) server implementation in Node.js.

Listen on predefined port for HL7 messages in format:

<VT>[HL7 Message]<FS><CR>

• HL7 MLP minimul layer protocol defined
• ACK message

• Node.js (v0.10+) and NPM
• Grunt.js

# you need Node.js and Grunt.js installed

# install dependencies and build
npm install
grunt

See example.js:

var mllp = require('mllp-node');

var server = new mllp.MLLPServer('127.0.0.1', 1234);

// Subscribe to inbound messages
server.on('hl7', function (data){
    console.log('received payload:', data);
});

// Send outbound messages
server.send('127.0.0.1', 4321, 'outbound-hl7-message', function (err, ackData) {
    // async callback code here
});
