nodejs操作mongodb可以使用mongoose：

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment.

安装mongoose：

npm install mongoose

///获取mongodb连接
var conn = mongoose.connect(‘mongodb://localhost/mytest‘);
    var Schema = mongoose.Schema
    , ObjectId = Schema.ObjectId;

    var Person = new Schema({
          title   : { type: String }
        , age     : { type: Number, min: 5, max: 20 }
        , meta    : {
              likes : [String]
            , birth : { type: Date }
          }
    });
    var p = mongoose.model(‘ModelName22‘, Person);

    var Blog = mongoose.model("ModelName22");

//保存新纪录
var blog1 = new Blog();
    blog1.id22 = 4;
    blog1.title="ully";
    blog1.save(function(err){
        if (err) {
            console.log(‘save failed‘);
        }
        console.log(‘save success‘);
    });

///查找记录
    Blog.find({_id:‘4f8678891256c4b819000002‘},function(err,docs){
             console.log(docs);
    });

//修改记录

var conditions = { name: ‘borne‘ }
    , update = { $set: { title: ‘xxxxb‘ }}
    , options = {};

    Blog.update({_id:‘4f866f35311977a81b000001‘},update,options,function(err,docs){
           console.log(docs+","+err);
    });

//删除记录

Blog.remove({_id:‘4f8678891256c4b819000002‘},function(err,docs){
           console.log(docs);
    });
