Introduction

This is a node.js driver for MongoDB. It's a port (or close to a port) of the library for ruby at http://github.com/mongodb/mongo-ruby-driver/.

A simple example of inserting a document.

		var es = require("elasticsearch-memcache");
		
    var client = new es({
			"host": "127.0.0.1",
			"port": 11211
		}, function(){
			
			client.set("/test/test/1", {
				"Lorizzle fo shizzle": "dolizzle sit amizzle",
				"consectetuer adipiscing": "elit.",
				"Nullam fo velit": "my shizz pizzle, suscipit quis, gravida vel, arcu.",
				"Pellentesque gangsta tortizzle.": "Sed eros. Fusce izzle dolor dapibus turpis tempizzle pimpin'."
			}, function(error, success){
				
				client.up("/test/test/1", {
					"Maurizzle ass away izzle turpis.": "Mofo izzle tortizzle.",
					"Pellentesque eleifend rhoncizzle boom shackalack.": "In bow wow wow shiznit platea dictumst."
				}, function(){
					
					client.get("/test/test/1", function(error, doc){
						console.log(doc);
						client.quit();
					})
				})
			})
		});
		
		client.on('error', function() {
		  console.log('client error', arguments);
		});

		client.on('end', function() {
		  console.log('client disconnected');
		});
