Protocol

The Punt protocol couldn’t be simpler either, the packet consists of a single byte for the message type, followed by the data itself. This small abstraction on top of node makes it more natural to work with UDP in JavaScript-land.

Server

When a Punt Server is bound “message” events are emitted, retaining the original message format, meaning if you send a Buffer, you receive a Buffer, if you send an Object, it is converted to JSON and you receive an Object.

var sock = punt.bind(‘udp://0.0.0.0:5000');

sock.on(‘message’, function(msg){
 console.log(msg);
});

Client

Naturally one or more clients may connect to the server to send messages. The API is shallow, with a single .send() method:

var sock = punt.connect(‘udp://0.0.0.0:5000');
sock.send(‘hello world’);
sock.send(new Buffer(‘hello world’));
sock.send({ hello: ‘world’ });
