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

response.removeHeader(name) Removes a header that's queued for implicit sending. Example: response.removeHeader('Content-Encoding');

crypto.publicDecrypt(public_key, buffer) Decrypts buffer with public_key. public_key can be an object or a string. If public_key is a string, it is treated as the key with no passphrase and will use RSA_PKCS1_PADDING. If public_key is an object, it is interpreted as a hash object with the keys: key : {String} - PEM encoded public key passphrase : {String} - Optional passphrase for the private key padding : An optional padding value, one of the following:constants.RSA_NO_PADDING constants.R

rl.prompt([preserveCursor]) Readies readline for input from the user, putting the current setPrompt options on a new line, giving the user a new spot to write. Set preserveCursor to true to prevent the cursor placement being reset to 0. This will also resume the input stream used with createInterface if it has been paused. If output is set to null or undefined when calling createInterface, the prompt is not written.

process.getgroups() Note: this function is only available on POSIX platforms (i.e. not Windows, Android) Returns an array with the supplementary group IDs. POSIX leaves it unspecified if the effective group ID is included but Node.js ensures it always is.

Class: https.Server This class is a subclass of tls.Server and emits events same as http.Server. See http.Server for more information.

fs.symlinkSync(target, path[, type]) Synchronous symlink(2). Returns undefined.

assert.equal(actual, expected[, message]) Tests shallow, coercive equality between the actual and expected parameters using the equal comparison operator ( == ). const assert = require('assert'); assert.equal(1, 1); // OK, 1 == 1 assert.equal(1, '1'); // OK, 1 == '1' assert.equal(1, 2); // AssertionError: 1 == 2 assert.equal({a: {b: 1}}, {a: {b: 1}}); //AssertionError: { a: { b: 1 } } == { a: { b: 1 } } If the values are not equal, an AssertionError is thrown with a message property

global {Object} The global namespace object. In browsers, the top-level scope is the global scope. That means that in browsers if you're in the global scope var something will define a global variable. In Node.js this is different. The top-level scope is not the global scope; var something inside an Node.js module will be local to that module.

zlib.deflate(buf[, options], callback)
