NodeJS wrapper to peek bytes from a given socket file descriptor

Package Exports

  • socket-peek

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (socket-peek) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

node-peek

NodeJs wrapper that peeks bytes from a given socket file descriptor

Installation

Install with npm:

$ npm install socket-peek

Examples

Read bytes of the next pending datagram using FIONREAD. As it takes a pointer as a parameter, it's straightforward using a Buffer as a parameter.

var fs = require('fs');
var express = require('express');
var https = require('https');
var peek = require('bindings')('peek.node').peek;

var key = fs.readFileSync('./peek-example-key.pem');
var cert = fs.readFileSync('./peek-example-cert.pem');
var https_options = {
    key: key,
    cert: cert
};
var PORT = 443;
var HOST = 'localhost';
app = express();

server = https.createServer(https_options, function(req, res) {
    res.writeHead(200);
    res.end("Hello");
}).listen(PORT, HOST);

function toHexString(byteArray) {
  return byteArray.map(function(byte) {
    return ('0' + (byte & 0xFF).toString(16)).slice(-2);
  }).join(' ')
}

server.on('connection', function(connection) {
    var buffer = new Buffer(1000);
    var ret = peek(connection._handle.fd, 1000, buffer);
    console.log('New connection, fd: ' + connection._handle.fd + ', ret: ' + ret);
    if (ret > 0) {
        console.log('Returned bytes: ' + buffer.slice(0,ret).toString('hex'));
    }

});
console.log('HTTPS Server listening on %s:%s', HOST, PORT);
