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
