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)

getHeapStatistics() Returns an object with the following properties { total_heap_size: 7326976, total_heap_size_executable: 4194304, total_physical_size: 7326976, total_available_size: 1152656, used_heap_size: 3476208, heap_size_limit: 1535115264 }

certificate.verifySpkac(spkac) Returns true if the given spkac data structure is valid, false otherwise. The spkac argument must be a Node.js Buffer. const cert = require('crypto').Certificate(); const spkac = getSpkacSomehow(); console.log(cert.verifySpkac(new Buffer(spkac))); // Prints true or false

Event: 'close' function () {} Emitted when close() is called. Also emitted when the input stream receives its 'end' event. The Interface instance should be considered "finished" once this is emitted. For example, when the input stream receives ^D, respectively known as EOT. This event is also called if there is no SIGINT event listener present when the input stream receives a ^C, respectively known as SIGINT.

request.write(chunk[, encoding][, callback]) Sends a chunk of the body. By calling this method many times, the user can stream a request body to a server--in that case it is suggested to use the ['Transfer-Encoding', 'chunked'] header line when creating the request. The chunk argument should be a Buffer or a string. The encoding argument is optional and only applies when chunk is a string. Defaults to 'utf8'. The callback argument is optional and will be called when this chunk of data is flu

fs.chown(path, uid, gid, callback) Asynchronous chown(2). No arguments other than a possible exception are given to the completion callback.

fs.read(fd, buffer, offset, length, position, callback) Read data from the file specified by fd. buffer is the buffer that the data will be written to. offset is the offset in the buffer to start writing at. length is an integer specifying the number of bytes to read. position is an integer specifying where to begin reading from in the file. If position is null, data will be read from the current file position. The callback is given the three arguments, (err, bytesRead, buffer).

tlsSocket.getCipher() Returns an object representing the cipher name and the SSL/TLS protocol version that first defined the cipher. Example: { name: 'AES256-SHA', version: 'TLSv1/SSLv3' } See SSL_CIPHER_get_name() and SSL_CIPHER_get_version() in https://www.openssl.org/docs/manmaster/ssl/SSL_CIPHER_get_name.html for more information.

crypto.createDiffieHellman(prime[, prime_encoding][, generator][, generator_encoding]) Creates a DiffieHellman key exchange object using the supplied prime and an optional specific generator. The generator argument can be a number, string, or Buffer. If generator is not specified, the value 2 is used. The prime_encoding and generator_encoding arguments can be 'binary', 'hex', or 'base64'. If prime_encoding is specified, prime is expected to be a string; otherwise a Buffer is expected. If ge
