hmac.digest([encoding]) Calculates the HMAC digest of all of the data passed using hmac.update(). The encoding can be 'hex', 'binary' or 'base64'. If encoding is provided a string is returned; otherwise a Buffer is returned; The Hmac object can not be used again after hmac.digest() has been called. Multiple calls to hmac.digest() will result in an error being thrown.

socket.localPort The numeric representation of the local port. For example, 80 or 21.

server.timeout See http.Server#timeout.

os.arch() Returns the operating system CPU architecture. Possible values are 'x64', 'arm' and 'ia32'. Returns the value of process.arch.

path.posix Provide access to aforementioned path methods but always interact in a posix compatible way.

Class: ChildProcess Instances of the ChildProcess class are EventEmitters that represent spawned child processes. Instances of ChildProcess are not intended to be created directly. Rather, use the child_process.spawn(), child_process.exec(), child_process.execFile(), or child_process.fork() methods to create instances of ChildProcess.

Stability: 2 - Stable Node.js includes a full-featured out-of-process debugging utility accessible via a simple TCP-based protocol and built-in debugging client. To use it, start Node.js with the debug argument followed by the path to the script to debug; a prompt will be displayed indicating successful launch of the debugger: $ node debug myscript.js < debugger listening on port 5858 connecting... ok break in /home/indutny/Code/git/indutny/myscript.js:1 1 x = 5; 2 setTimeout(() => {

path.format(pathObject) Returns a path string from an object. This is the opposite of path.parse. If pathObject has dir and base properties, the returned string will be a concatenation of the dir property, the platform-dependent path separator, and the base property. If the dir property is not supplied, the root property will be used as the dir property. However, it will be assumed that the root property already ends with the platform-dependent path separator. In this case, the returned strin

replServer.defineCommand(keyword, cmd) keyword <String> cmd <Object> | <Function> Makes a command available in the REPL. The command is invoked by typing a . followed by the keyword. The cmd is an object with the following values: help - help text to be displayed when .help is entered (Optional). action - a function to execute, potentially taking in a string argument, when the command is invoked, bound to the REPLServer instance (Required). If a function is provided

assert.strictEqual(actual, expected[, message]) Tests strict equality as determined by the strict equality operator ( === ). const assert = require('assert'); assert.strictEqual(1, 2); // AssertionError: 1 === 2 assert.strictEqual(1, 1); // OK assert.strictEqual(1, '1'); // AssertionError: 1 === '1' If the values are not strictly equal, an AssertionError is thrown with a message property set equal to the value of the message parameter. If the message parameter is undefined, a default
