# TCP in React Native node's [net](https://nodejs.org/api/net.html) API in React Native This module is used by [Peel](http://www.peel.com/) ## Install * Create a new react-native project. [Check react-native getting started](http://facebook.github.io/react-native/docs/getting-started.html#content) * In your project dir: ``` npm install --save react-native-tcp ``` ### `iOS` * Drag TcpSockets.xcodeproj from node_modules/react-native-tcp/ios into your XCode project. * Click on the project in XCode, go to Build Phases, then Link Binary With Libraries and add `libTcpSockets.a` ### `Android` * `android/settings.gradle` ```gradle ... include ':react-native-tcp' project(':react-native-tcp').projectDir = new File(settingsDir, '../node_modules/react-native-tcp/android/core') ``` * `android/app/build.gradle` ```gradle dependencies { ... compile project(':react-native-tcp') } ``` * register module (in MainActivity.java) ```java ... import com.peel.react.*; // <--- import public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler { ... @Override protected List getPackages() { return Arrays.asList( new MainReactPackage(), new TcpSocketsModule()); // <- add here } } ``` Buckle up, Dorothy ## Usage ### package.json _only if you want to write require('net') in your javascript_ ```json { "browser": { "net": "react-native-tcp" } } ``` ### JS _see/run [index.js](examples/rctsockets) for a complete example, but basically it's just like net_ ```js 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: ```js global.Buffer = global.Buffer || require('buffer').Buffer ``` ### TODO add select tests from node's tests for net ## Contributors [Andy Prock](https://github.com/aprock) PR's welcome! _originally forked from [react-native-udp](https://github.com/tradle/react-native-udp)_
