Event: 'end' Emitted when the other end of the socket sends a FIN packet. By default (allowHalfOpen == false) the socket will destroy its file descriptor once it has written out its pending write queue.

Class: SyntaxError A subclass of Error that indicates that a program is not valid JavaScript. These errors may only be generated and propagated as a result of code evaluation. Code evaluation may happen as a result of eval, Function, require, or vm. These errors are almost always indicative of a broken program. try { require('vm').runInThisContext('binary ! isNotOk'); } catch(err) { // err will be a SyntaxError } SyntaxError instances are unrecoverable in the context that created them – th

Event: 'OCSPRequest' function (certificate, issuer, callback) { } Emitted when the client sends a certificate status request. The server's current certificate can be parsed to obtain the OCSP URL and certificate ID; after obtaining an OCSP response callback(null, resp) is then invoked, where resp is a Buffer instance. Both certificate and issuer are Buffer DER-representations of the primary and issuer's certificates. They can be used to obtain the OCSP certificate ID and OCSP endpoint URL. Al
