node http(s) server graceful shutdown

Adds a shutdown(callback) to nodes http(s) servers. shutdown() will stop accepting new connections and waits until all requests are finished. This is very similar to the node builtin close() function with the only difference that shutdown() destroys idle connections (e.g. keep alive connections) using a timeout (10 seconds as default) without data transfer.

Usage

1var enableGracefulShutdown = require('server-graceful-shutdown');
2
3var server = http.createServer(function(req, res) {
4  // do stuff
5});
6
7server.listen(80);
8
9// enhance server with a 'shutdown' function
10enableGracefulShutdown(server);
11// you can set the socket idle timeout using the second parameter 
12// e.g. enableGracefulShutdown(server, 5000);
13
14// some time later...
15server.shutdown(function() {
16	// all requests are finished 
17	// we can 
18	// process.exit() 
19	// now
20});
