Http-Shutdown

Shutdown a Nodejs HTTP server gracefully by terminating the listening socket, then destroying all keep-alive idle sockets all while allowing in-flight requests to finish. Don't be fooled by other "shutdown" techniques. This solution is complete and takes into account many factors left out by other solutions.

Usage

There are currently two ways to use this library. The first is explicit wrapping of the Server object:

// Create the http server
var server = require('http').createServer(function(req, res) {
  res.end('Good job!');
});

// Wrap the server object with additional functionality
server = require('http-shutdown')(server);

// Sometime later, shutdown the server.
server.shutdown(function() {
  console.log('Everything is cleanly shutdown.');
});

The second is implicitly adding prototype functionality to the Server object:

// .extend adds a .withShutdown prototype method to the Server object
var httpShutdown = require('http-shutdown').extend();

var server = require('http').createServer(function(req, res) {
  res.end('God job!');
}).withShutdown(); // <-- Easy to chain. Returns the Server object

// Sometime later, shutdown the server.
server.shutdown(function() {
  console.log('Everything is cleanly shutdown.');
});
