和尚vs猫鼬for Mongodb

问题描述

我正在学习NodeJ.

I'm learning NodeJs.

要连接并使用NodeJS的MongoDB，我看到了很多使用Monk或Mongoose的示例.

To connect to and use MongoDB from NodeJS, I see a lot of examples using either Monk or Mongoose.

这两个库是否等效?它们具有相同的功能还是各自具有特定的用途?

Are these two libraries equivalent ? Do they have the same features or do they each have a specific purpose ?

作为NodeJS的初学者，我应该使用哪个?

As a beginner with NodeJS, which should I use ?

以下是一些使用Monk的代码示例:

Here are some examples of code that uses Monk :

var mongo = require('mongodb');
var monk = require('monk');
var db = monk('localhost:27017/nodejsapp');

----
exports.userlist = function(db) {
    return function(req, res) {
        var collection = db.get('users');
        collection.find({},{},function(e,docs){
            res.render('userlist', {
                "userlist" : docs
            });
        });
    };
};

，这里是一个使用猫鼬的示例:

and here a sample that uses Mongoose :

   var mongoose = require('mongoose');
----
 mongoose.connect('localhost', 'test');
 var db = mongoose.connection;
  db.on('error', console.error.bind(console, 'connection error:'));
  db.once('open', function callback() {
   console.log('Connected to DB');
});

// User Schema
var userSchema = mongoose.Schema({
   username: { type: String, required: true, unique: true },
   email: { type: String, required: true, unique: true },
  password: { type: String, required: true},
});

推荐答案

它们是不同的，尽管它们是解决同一基本问题的两种方法.猫鼬是一个非常复杂的完整ORM.功能更多，但复杂性更高.和尚的范围较小，因此更容易理解.

They are different, although they are two approaches to the same basic problem. Mongoose is a quite sophisticated full-on ORM. More features, but more complexity. Monk is smaller in scope and thus easier to understand.

我的建议是直接使用基本的mongodb驱动程序模块开始编码.当您了解它的工作原理以及它的某些部分令人讨厌时，您将了解monk的好处，并可以尝试一下看看是否喜欢它.我不建议初学者使用mongoose. Mongodb已经足够技巧来学习，虽然Mongoose可能会有所帮助，但它的API十分神奇，并假定您已经知道mongodb的棘手方面.

My suggestion is start coding with the basic mongodb driver module directly. When you understand how that works, and how parts of it are annoying, you will understand the benefit of monk and can try that out to see if you like it. I wouldn't recommend mongoose to a beginner. Mongodb is already tricky enough to learn and while mongoose can be helpful, it's API is quite magical and assumes you already know the tricky aspects of mongodb.
