socket.bytesRead The amount of received bytes.

socket.remoteAddress The string representation of the remote IP address. For example, '74.125.127.100' or '2001:4860:a005::68'. Value may be undefined if the socket is destroyed (for example, if the client disconnected).

Event: 'lookup' Emitted after resolving the hostname but before connecting. Not applicable to UNIX sockets. err {Error|Null} The error object. See dns.lookup(). address {String} The IP address. family {String|Null} The address type. See dns.lookup(). host {String} The hostname.

tlsSocket.getSession() Returns the ASN.1 encoded TLS session or undefined if none was negotiated. Could be used to speed up handshake establishment when reconnecting to the server.

Stability: 2 - Stable The child_process module provides the ability to spawn child processes in a manner that is similar, but not identical, to popen(3). This capability is primarily provided by the child_process.spawn() function: const spawn = require('child_process').spawn; const ls = spawn('ls', ['-lh', '/usr']); ls.stdout.on('data', (data) => { console.log(`stdout: ${data}`); }); ls.stderr.on('data', (data) => { console.log(`stderr: ${data}`); }); ls.on('close', (code) => {

buf.writeDoubleLE(value, offset[, noAssert]) value <Number> Bytes to be written to Buffer offset <Number> 0 <= offset <= buf.length - 8 noAssert <Boolean> Default: false Return: <Number> The offset plus the number of written bytes Writes value to the Buffer at the specified offset with specified endian format (writeDoubleBE() writes big endian, writeDoubleLE() writes little endian). The value argument should be a valid 64-bit double. Behavior is not defined w

server.unref() Calling unref on a server will allow the program to exit if this is the only active server in the event system. If the server is already unrefd calling unref again will have no effect. Returns server.

Stability: 2 - Stable A stream is an abstract interface implemented by various objects in Node.js. For example a request to an HTTP server is a stream, as is process.stdout. Streams are readable, writable, or both. All streams are instances of EventEmitter. You can load the Stream base classes by doing require('stream'). There are base classes provided for Readable streams, Writable streams, Duplex streams, and Transform streams. This document is split up into 3 sections: The first section e

child.stdio <Array> A sparse array of pipes to the child process, corresponding with positions in the stdio option passed to child_process.spawn() that have been set to the value 'pipe'. Note that child.stdio[0], child.stdio[1], and child.stdio[2] are also available as child.stdin, child.stdout, and child.stderr, respectively. In the following example, only the child's fd 1 (stdout) is configured as a pipe, so only the parent's child.stdio[1] is a stream, all other values in the array

http.METHODS <Array> A list of the HTTP methods that are supported by the parser.
