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(errorsuccess){
                
                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(errordoc){
                        console.log(doc);
                        client.quit();
                    })
                })
            })
        });
        
        client.on('error', function() {
          console.log('client error', arguments);
        });
 
        client.on('end', function() {
          console.log('client disconnected');
        });

API

        .get( key, ?GET_PARAMETER, callback ) -> GET Request, get an document, indice, setting or something else over the API.
            
            es.get("/test/test/1", function(errordoc){ console.log(doc); })
            es.get("/test/test/1", { fields: "fieldkey1,fieldkey2" }, function(errordoc){ console.log(doc); })
            es.get("/_stats", function(errorstats){ console.log(stats); })
            
        .mget( docs, callback ) -> GET Request, collect multiple documents over one request
            es.mget({
                "docs": [
                    { "_index": "test", "_type": "test", "_id": 1 },
                    { "_index": "test", "_type": "test", "_id": 2 },
                ]
            }, function(errordocs){})
        
        .set( key, value, ?GET_PARAMETER, callback ) -> POST Request, can be an document, the indice settings or whatever over the API.
            es.set("/test/test/1", { "fieldkey1": "fieldvalue1", "fieldkey2": "fieldvalue2" }, function(errorsuccess){})
        
        .up( key, value, ?GET_PARAMETER, callback ) -> Update an document
            es.set("/test/test/1", { "fieldkey3": "fieldvalue3" }, function(errorsuccess){})
