TCP in React Native

node's net API in React Native

Install

npm install @staltz/react-native-tcp --save

Link in the native dependency

react-native link @staltz/react-native-tcp

Additional dependencies

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

  1. install rn-nodeify as a dev-dependency npm install --save-dev rn-nodeify
  2. run rn-nodeify manually rn-nodeify --install stream,process,util --hack
  3. 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') or require('tls') in your javascript

{
  "react-native": {
    "net": "@staltz/react-native-tcp",
    "tls": "@staltz/react-native-tcp/tls"
  }
}

JS

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

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

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)
});

TLS support

TLS is only supported in the client interface. To use TLS, use the tls.connect() syntax and not socket = new tls.Socket() syntax.

const socket = tls.connect({port: 50002, host:'electrum.villocq.com', rejectUnauthorized: false}, () => {
  socket.write('{ "id": 5, "method": "blockchain.estimatefee", "params": [2] }\n')
  console.log('Connected')
})

socket.on('data', (data) => {
  console.log('data:' + data.toString('ascii'))
})
