simple tcp client / server for easy json objects / data transmission


Simple tcp client / server for easy json objects / data transmission supporting tls

npm install ee-net

The Server and Connection class do have almost all properties and events of the native node.js «net» API. see net API

The constructor of the server class takes the options described at tls.createServer for a tls enabled server and the options described at net.createServer for non tls mode. you may pass a port and a host option as well.

var net = require( "ee-net" );

var server = new net.Server( { port: 9999 } );

The connection event is called when a client has established a new connection on the server

server.on( "connection", function( connection ){
	// see the «connection» chapter below for the docs on connections
} );

The constructor of the connection class takes the options described at tls.connect for tls enabled connections and the options «port» and «host» for non tls enabled connections.

var connection = new net.Connection( { host:, port: 9999 } );

The message event is called when a message was received and decoeded successfully

connection.on( "message", function( message ){
	log( message );
} )

You may transmit messages using the «send» method

connection.send( { myJSON: "object" } );

The remote and local property return the remote / local ip / host configuration of the connection

log( connection.remote ); // { address:, family: "IPv4", port: 9999 }
var   net 			= require( "ee-net" )
	, server 		= new net.Server().listen();

server.on( "conenction", function( connection ){
	connection.on( "message", function( msg ){
		log( msg );  // { hi: "fabian" }
		connection.send( msg );
	} );
} );

// wait until the server is online so we know its port
server.on( "listening", function(){
	var client = new Connection( { 
		port: server.address.port
	} );

	client.on( "message", function( msg ){
		log( msg ); // { hi: "fabian" }
	} );

	client.send( { hi: "fabian" } );
} );

You may implement custom protocol handlers, see ee-protocol-json for more information. You may pass an alternative protocol implementation to the constructors of the Server / Connection using the «protocol» property of the options object.
