    UDP in React Native

    node's dgram API in React Native

    This module is used by Tradle

    Install

    npm install --save react-native-udp
    

    Link in the native dependency

    react-native link react-native-udp
    # OR, if you're using react-native older than 0.31:
    rnpm link react-native-udp
    

    Android

    • Register and load the Native Module in your Main application (import, getPackages)
      • Note: prior to react-native 0.29.2, this should happen in your Main Activity
    ...
     
    import com.tradle.react.UdpSocketsModule; // <--- import // 
     
    public class MainApplication extends Application implements ReactApplication {
        ...
        @Override
        protected List<ReactPackage> getPackages() {
            return Arrays.<ReactPackage>asList(
                new MainReactPackage(),
                new UdpSocketsModule() // <- add here // 
            );
        }
    }

    Buckle up, Dorothy

    Usage

    package.json

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

    {
      "browser": {
        "dgram": "react-native-udp"
      }
    }

    JS

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

    var dgram = require('dgram')
    // OR, if not shimming via package.json "browser" field:
    // var dgram = require('react-native-udp')
    var socket = dgram.createSocket('udp4')
    socket.bind(12345)
    socket.once('listening', function() {
      var buf = toByteArray('excellent!')
      socket.send(buf, 0, buf.length, remotePort, remoteHost, function(err) {
        if (err) throw err
     
        console.log('message was sent')
      })
    })
     
    socket.on('message', function(msg, rinfo) {
      console.log('message was received', msg)
    })

    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 UdpSockets to pick it up:

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

    TODO

    add select tests from node's tests for dgram
