nspoint

Split a duplex object stream intro multiply duplex streams

Installation

npm install nspoint

Example

You have a some duplex transport socket there takes and outputs objects wrap it in each end with nspoint to split it via namespaces.

var nspoint = require('nspoint');

// e.q. server side
var A = nspoint();
transport.pipe(A).pipe(transport);

var aFoo = A.namespace('foo');
var aBar = A.namespace('bar');

aFoo.write('foo message');
aBar.once('data', function (msg) {
  // gets gets {object: 'bar'}
  console.log(msg);
});

// e.q. client side
var B = nspoint();
transport.pipe(B).pipe(transport);

var bFoo = B.namespace('foo');
var bBar = B.namespace('bar');

bFoo.once('data', function (msg) {
  // gets 'foo message'
  bBar.write({object: 'bar'});
});

Documentation

point = nspoint()

This creates an object stream interface from which you can create namespaces. When the source stream ends it will be boardcasted to all active namespaces.

point.namespace(name)

Creates an object stream there used the point as a resource for writing to and reading data from. When this stream ends the end event to is relayed to the other end and the underlying logic for this particular namespace is cleaned up.

Note if an indentical namespace have already been created, this function will return the exact same stream object.
