Handling Node.js socket data
15,918
According to the documentation, you must specify an encoding to get a String instead of a Buffer:
Event: 'data'#
Buffer object
Emitted when data is received. The argument data will be a Buffer or String. Encoding of data is set by socket.setEncoding().
You could configure the socket to get the data in UTF-8, for example, with:
socket.setEncoding('utf8');

I have server receiving data from a client [GPS Device]. I have problem presenting the data (i.e the results obtained from the client) in a readable format. Below are the things I have tried.
Doing:
console.log(data)
I get
<Buffer d0 d7 3d 00 c4 56 7e 81>
Also tried
console.log(data.toString())
But I get unwanted results:See below:

Here is my full code:
var net = require('net'); var fs = require('fs'); var server = net.createServer(function (socket) { console.log('Server started: Waiting for client connection ...'); console.log('Client connected:port,address: '+socket.remotePort, socket.remoteAddress); socket.on('data', function (data) { var date = new Date(); var today = date.getDate()+'_'+date.getMonth(); fs.appendFile(today+'_log.txt', data, function (err) { if (err) throw err; console.log(data.toString()) }); }); }); server.listen(my_port, my_ip);
Thanks for your input.
