提取猫鼬与忏悔

Question

我很好奇是否有人能够提供一些有关抽象使用Node.js + Restify + Mongoose构建的API的最佳方法的见解.在来自MVC/PHP背景之后,发现Node应用程序没有字符串/定义结构很有意思.

截至目前,我有我的app.js文件,自动加载我的routes.js文件,所有模型js文件等.

困惑主要在于我的路线应该如何与来自Mongo的数据进行交互.这是我的代码如何布局的基本概述.

app.js:

/**
 * Require Dependencies
 */
var restify    = require('restify')
    , mongoose = require('mongoose')
    , config   = require('./config')
    , routes   = require('./routes');

/**
 * Create Server & Define Settings
 */
var server = restify.createServer({
    name: config.name,
    version: config.version
});

/**
 * Common Handlers
 */
server.use(restify.acceptParser(server.acceptable));
server.use(restify.queryParser());
server.use(restify.bodyParser());
server.use(restify.jsonp());

/**
 * Connect to Mongo Database
 */
 mongoose.connect(config.mongo.uri, function(err) {

    // assign connection to var so we can pass it down the chain
    var db = mongoose.connection;

    // handle connection error
    db.on('error', console.error.bind(console, 'connection error:'));

    // handle connection success
    db.once('open', function callback () {

        /**
         * Start Routing API Calls
         */
        routes.route(server, db);

    });

});

/**
 * Start Server & Bind to Port
 */
server.listen(config.port, function () {
    console.log('%s v%s listening on port %s in %s mode.', server.name, server.version,          config.port, config.env);
});

routes.js:

module.exports.route = function(server, db) {

    var Users = require('./models/users.js');

    /**
     * Users
     */

    server.get('/users', function (req, res, next) {

        res.send(Users.list(db, req, res));

        return next();

    });

    server.get('/users/:user_id', function (req, res, next) {

        res.send(Users.get(db, req, res));

        return next();

    });

}  

models/users.js:

// fake database
var users = [
    {
        name: 'Nick P',
        email: 'nick@domain.com'
    },
    {
        name: 'Zack S',
        email: 'zack@domain.com'
    }
];

exports.list = function(db, req, res) {

return users;

};

exports.get = function(db, req, res) {

    return users[req.params.user_id];

};

如您所见,我正在使用一个简单对象的"假数据库".我在哪里/如何引入Mongoose层与我们的数据库进行通信？我最关心的是我应该如何使用模式和导出.任何代码示例或方向都会很棒.

这是一个我通常做的简单例子Express,它有点同样的东西Restify.您可以Mongoose以相同的方式管理模式,但在Restify路线中.

app.js:

var express = require('express');     
var app = express();

app.configure(function () {
    app.use(express.logger('dev'));
    app.use(express.bodyParser());
});

// connection to mongoDB
var mongoose = require('mongoose');
mongoose.connect('mongodb:mongoURI');    

var user = require('./routes/users');

app.get('/users/list', user.list);

app.listen(3000);

models/user.js:

var mongoose = require('mongoose')
   ,Schema = mongoose.Schema
   ,ObjectId = Schema.ObjectId;

var userSchema = new Schema({
    id: ObjectId,
    name: {type: String, default: ''},
    email: {type: String, default: ''}
});

module.exports = mongoose.model('User', userSchema);

routes/users.js:

var User = require('../models/user.js');

exports.list = function(req, res) {
    User.find(function(err, users) {
        res.send(users);
    });
};
