datagram-stream

---------------

[![Build Status](https://travis-ci.org/wankdanker/node-datagram-stream.svg)](https://travis-ci.org/wankdanker/node-datagram-stream)

A streaming UDP module with broadcast, multicast and unicast options.

install

-------

```bash

npm install datagram-stream

```

usage

-----

## multicast

```js

var udp = require('datagram-stream');

var stream = udp({

    address     : '0.0.0.0'   //address to bind to

    , multicast : '239.5.5.5' //multicast ip address to send to and listen on

    , port      : 5555        //udp port to send to

    , bindingPort : 5556      //udp port to listen on. Default: port

    , reuseAddr : true        //boolean: allow multiple processes to bind to the

                              //         same address and port. Default: true

    , loopback  : true        //boolean: whether or not to receive sent datagrams

                              //         on the loopback device. Only applies to

                              //         multicast. Default: false

});

//pipe whatever is received to stdout

stream.pipe(process.stdout);

//pipe whatever is received on stdin over udp

process.stdin.pipe(stream);

```

## broadcast

```js

var udp = require('datagram-stream');

var stream = udp({

    address     : '0.0.0.0'         //address to bind to

    , broadcast : '255.255.255.255' //broadcast ip address to send to

    , port      : 5555              //udp port to send to

    , bindingPort : 5556            //udp port to listen on. Default: port

    , reuseAddr : true              //boolean: allow multiple processes to bind to the

                                    //         same address and port. Default: true

 });

//pipe whatever is received to stdout

stream.pipe(process.stdout);

//pipe whatever is received on stdin over udp

process.stdin.pipe(stream);

```

## unicast

```js

var udp = require('datagram-stream');

var stream = udp({

    address     : '0.0.0.0'   //address to bind to

    , unicast   : '127.0.0.1' //unicast ip address to send to

    , port      : 5555        //udp port to send to

    , bindingPort : 5556      //udp port to listen on. Default: port

    , reuseAddr : true        //boolean: allow multiple processes to bind to the

                              //         same address and port. Default: true

 });

//pipe whatever is received to stdout

stream.pipe(process.stdout);

//pipe whatever is received on stdin over udp

process.stdin.pipe(stream);
