features

• easy setup and connect mongodb

  简洁的连接方式

  var db = new MaoGou(params, 'user');

• mongodb-like

采用类似mongodb客户端的简洁灵活的语法

 db.user.find({name: 'linkwisdom'}).then(print);

• promise and deffred are augmented, handler data in a midware-pipe line with then-chains

采用promise防止异步调用的错乱结构,同时支持中间件处理

 db.user.find({age: 19})
     .then(filter)
     .done(print);

• support sucess and fail notifying events for more flexible extentions

支持失败与成功的事件处理，利用事件机制可以根据更灵活地扩展程序

 db.user.save([{user: 'jack'}, {user: 'mark'}])
     .onSuccess(function(result) {
         //cons~
     })
     .onError(function(err) {
         //si~
     })
     .done(print);

• setup the argument options in an uncurring pattern

采用反柯里的语法结构进行参数设置

 db.vistor.geoNear([130.19,39.102])
      .maxDsitance(0.39)
      .limit(25)
      .done(print);

• serveral useful functions, mapreduce, find, update, remove, geoNear, cout, etc. are supported and augmented

支持简化的mapreduce，find, update,remove,geoNear,count等过程

 db.vistor.update({age: 19},{age: 20})
     .set({w: 1})
     .done(print);

• connect on demmand, close any time;

按需连接，即时关闭

 db.user.find({}).done(function(err, docs) {
     db.user.close();
 });

更多新特性在完善

web-client support, 与couchDB一样，我们希望能够提供一个支持http数据库操作API接口
