   * or modules besides the default ones, add more packages here.
   */
  @Override
  protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          new TcpSocketsModule()           // <- add here //
      );
  }
}

Buckle up, Dorothy

Usage

package.json

only if you want to write require('net') in your javascript

{
  "browser": {
    "net": "react-native-tcp"
  }
}

JS

see/run index.js for a complete example, but basically it's just like net

var net = require('net');
// OR, if not shimming via package.json "browser" field:
// var net = require('react-native-tcp')

var server = net.createServer(function(socket) {
	socket.write('excellent!');
}).listen(12345);

var client = net.createConnection(12345);

client.on('error', function(error) {
	console.log(error)
});

client.on('data', function(data) {
	console.log('message was received', data)
});

Note

If you want to send and receive node Buffer objects, you'll have to "npm install buffer" and set it as a global for TcpSockets to pick it up:

global.Buffer = global.Buffer || require('buffer').Buffer

TODO

add select tests from node's tests for net
