Node.js & Express - 应用程序结构的全局模块和最佳实践

我正在构建一个节点.js应用程序，它是一个REST api，使用express和mongoose为我的mongodb。我现在已经设置了所有 CRUD 端点，但我只是想知道两件事。

1. 如何扩展这种路由方式，具体而言，如何在路由之间共享模块。我希望我的每条路由都进入一个新文件，但显然只有一个数据库连接，正如你所看到的，我已经将猫鼬包含在人们的顶部.js。

我

2. 是否必须在我的人中写出模型的模式 3 次.js？第一个模式定义模型，然后我列出 createPerson 和 updatePerson 函数中的所有变量。这感觉就像我当年制作php/mysql CRUD的方式，哈哈。对于更新函数，我尝试编写一个循环来循环"p"以自动检测要更新的字段，但无济于事。任何提示或建议都会很棒。

另外，我希望对整个应用程序有任何意见，作为节点的新手，很难知道您做某事的方式是最有效或"最佳"的做法。谢谢！

应用.js

// Node Modules
var express     = require('express');
    app         = express();
    app.port    = 3000;

// Routes
var people      = require('./routes/people');
/*
var locations   = require('./routes/locations');
var menus       = require('./routes/menus');
var products    = require('./routes/products');
*/

// Node Configure
app.configure(function(){
  app.use(express.bodyParser());
  app.use(app.router);
});

// Start the server on port 3000
app.listen(app.port);

/*********
ENDPOINTS 
*********/
// People
app.get('/people', people.allPeople); // Return all people
app.post('/people', people.createPerson); // Create A Person
app.get('/people/:id', people.personById); // Return person by id
app.put('/people/:id', people.updatePerson); // Update a person by id
app.delete('/people/:id', people.deletePerson); // Delete a person by id
console.log('Server started on port ' + app.port);
