An implementation of the FIX protocol (Financial Information Exchange).

Currently the implementation is pre-beta.

New development

New development is being done on https://github.com/falconair/fix.js. This codebase turned out to be over-engineered. fix.js is much simpler, but its infrastructure is not as developed (package file, 'npm install ...' system, tests, etc.)

Some code from fix.js (similar to this project) is also driving a web app to parse fix protocol messages at http://fixparser.targetcompid.com

Install

npm install nodefix

Test {Server,Client}

You can run a test server:

node testFIXServer.js

then a test client, too:

node testFIXClient.js

Both programs should start communicating with each other. Wait a few seconds to see heart-beat messages fly by.

API

###Server:

var fix = require('fix');

var opt = {};
var server = fix.createServer(opt, function(session){

    session.on("logon", function(sender, target){ console.log("EVENT logon: "+ sender + ", " + target); });
    session.on("incomingmsg", function(sender,target,msg){ console.log("Server incomingmsg: "+ JSON.stringify(msg)); });
    session.on("outgoingmsg", function(sender,target,msg){ console.log("Server outgoingmsg: "+ JSON.stringify(msg)); });

});
server.listen(1234, "localhost", function(){});

Server events:

newacceptor (port)
Triggered on new connections from clients

Server methods:

write(sessionID, data)
Converts an associative array to a FIX message and sends it to the counter party with given comp ID
logoff(sessionID, reason)
Logs off a given comp ID
kill(sessionID, reason)
Ends connection of a given comp ID, without logging off

###Client:

var fix = require('fix');

var opt = {};
var client = fix.createClient("FIX.4.2", "initiator", "acceptor",opt);
client.connectAndLogon(1234,"localhost");

client.on("connect", function(){ console.log("EVENT connect"); });
client.on("end", function(){ console.log("EVENT end"); });
client.on("logon", function(sender, target){ console.log("EVENT logon: "+ sender + ", " + target); });
client.on("logoff", function(sender, target){ console.log("EVENT logoff: "+ sender + ", " + target); });
client.on("incomingmsg", function(sender,target,msg){ console.log("EVENT incomingmsg: "+ JSON.stringify(msg)); });
client.on("outgoingmsg", function(sender,target,msg){ console.log("EVENT outgoingmsg: "+ JSON.stringify(msg)); });

Client events:

newclient (version, sender, target, port, host)
Triggered on new connections to servers

Client methods:

write(data)
Converts an associative array to a FIX message and sends it to the counter party
logoff(reason)
Logs off connection
kill(reason)
Ends connection without logging off

###Common: Events commons to servers and clients:

connect (host, port, 'initiator' or 'acceptor')
Triggered on new connections
end (sender, target)
Triggered when connections end
error (err)
Triggered on error
logon (sender, target)
Triggered when new client completes logon
incomingmsg (sender, target, msg)
Triggered on messages coming over the network
outgoingmsg (sender, target, msg)
Triggered on messages going out to the network
incomingresync (sender, target, msg)
Triggered on messages coming over the network, which may have already been processed. Should not matter other than on re-connections
outgoingresync (sender, target, msg)
Triggered on messages going out to the network, which may have already been processed. Should not matter other than on re-connections
