Install

Create a new react-native project. Check react-native getting started
In your project dir:

npm install react-native-tcp --save

Note for iOS: If your react-native version < 0.40 install with this tag instead:

npm install react-native-tcp@3.1.0 --save

if using Cocoapods

Update the following line with your path to node_modules/ and add it to your podfile:

pod 'TcpSockets', :path => '../node_modules/react-native-tcp'

Link in the native dependency

react-native link react-native-tcp

Additional dependencies

Due to limitations in the react-native packager, streams need to be hacked in with rn-nodeify

install rn-nodeify as a dev-dependency npm install --save-dev rn-nodeify
run rn-nodeify manually rn-nodeify --install stream,process,util --hack
optionally you can add this as a postinstall script "postinstall": "rn-nodeify --install stream,process,util --hack"

Usage

package.json

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

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

JS

see/run index.ios.js/index.android.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)
});
