socket.remoteFamily The string representation of the remote IP family. 'IPv4' or 'IPv6'.

socket.ref() By default, binding a socket will cause it to block the Node.js process from exiting as long as the socket is open. The socket.unref() method can be used to exclude the socket from the reference counting that keeps the Node.js process active. The socket.ref() method adds the socket back to the reference counting and restores the default behavior. Calling socket.ref() multiples times will have no additional effect. The socket.ref() method returns a reference to the socket so calls

request.flushHeaders() Flush the request headers. For efficiency reasons, Node.js normally buffers the request headers until you call request.end() or write the first chunk of request data. It then tries hard to pack the request headers and data into a single TCP packet. That's usually what you want (it saves a TCP round-trip) but not when the first data isn't sent until possibly much later. request.flushHeaders() lets you bypass the optimization and kickstart the request.

Event: 'message' worker <cluster.Worker> message <Object> Emitted when any worker receives a message. See child_process event: 'message'.

Event: 'fork' worker <cluster.Worker> When a new worker is forked the cluster module will emit a 'fork' event. This can be used to log worker activity, and create your own timeout. var timeouts = []; function errorMsg() { console.error('Something must be wrong with the connection ...'); } cluster.on('fork', (worker) => { timeouts[worker.id] = setTimeout(errorMsg, 2000); }); cluster.on('listening', (worker, address) => { clearTimeout(timeouts[worker.id]); }); cluster.on('

diffieHellman.getGenerator([encoding]) Returns the Diffie-Hellman generator in the specified encoding, which can be 'binary', 'hex', or 'base64'. If encoding is provided a string is returned; otherwise a Buffer is returned.

cluster.disconnect([callback]) callback <Function> called when all workers are disconnected and handles are closed Calls .disconnect() on each worker in cluster.workers. When they are disconnected all internal handles will be closed, allowing the master process to die gracefully if no other event is waiting. The method takes an optional callback argument which will be called when finished. This can only be called from the master process.

Class: Hmac The Hmac Class is a utility for creating cryptographic HMAC digests. It can be used in one of two ways: As a stream that is both readable and writable, where data is written to produce a computed HMAC digest on the readable side, or Using the hmac.update() and hmac.digest() methods to produce the computed HMAC digest. The crypto.createHmac() method is used to create Hmac instances. Hmac objects are not to be created directly using the new keyword. Example: Using Hmac objects as

cipher.final([output_encoding]) Returns any remaining enciphered contents. If output_encoding parameter is one of 'binary', 'base64' or 'hex', a string is returned. If an output_encoding is not provided, a Buffer is returned. Once the cipher.final() method has been called, the Cipher object can no longer be used to encrypt data. Attempts to call cipher.final() more than once will result in an error being thrown.

ecdh.setPrivateKey(private_key[, encoding]) Sets the EC Diffie-Hellman private key. The encoding can be 'binary', 'hex' or 'base64'. If encoding is provided, private_key is expected to be a string; otherwise private_key is expected to be a Buffer. If private_key is not valid for the curve specified when the ECDH object was created, an error is thrown. Upon setting the private key, the associated public point (key) is also generated and set in the ECDH object.
