node.js – 在不同的文件中划分节点应用程序

例如,如果您要将数据库逻辑从主应用程序中分离出来,您应该能够这样做,因为数据库逻辑不应该依赖于应用程序或io – 它应该能够独立工作,而您要求它进入你的应用程序的其他部分使用它.

这是一个相当基本的例子 – 它比实际代码更伪代码,因为重点是通过示例演示模块化,而不是编写一个有效的应用程序.它也是您决定构建应用程序的众多方法中的一种.

// =============================
// db.js

var mongoose = require('mongoose');
mongoose.connect(/* ... */);

module.exports = {
  User: require('./models/user');
  OtherModel: require('./models/other_model');
};


// =============================
// models/user.js (similar for models/other_model.js)

var mongoose = require('mongoose');
var User = new mongoose.scheR_370_11845@a({ /* ... */ });
module.exports = mongoose.model('User',User);


// =============================
// routes.js

var db = require('./db');
var User = db.User;
var OtherModel = db.otherModel;

// This module exports a function,which we call call with
// our Express application and Socket.IO server as arguments
// so that we can access them if we need them.
module.exports = function(app,io) {
  app.get('/',function(req,res) {
    // home page logic ...
  });

  app.post('/users/:id',res) {
    User.create(/* ... */);
  });
};


// =============================
// realtime.js

var db = require('./db');
var OtherModel = db.otherModel;

module.exports = function(io) {
  io.sockets.on('connection',function(socket) {
    socket.on('someEvent',function() {
      OtherModel.find(/* ... */);
    });
  });
};


// =============================
// application.js

var express = require('express');
var sio = require('socket.io');
var routes = require('./routes');
var realtime = require('./realtime');

var app = express();
var server = @R_673_10107@.createServer(app);
var io = sio.listen(server);

// all your app.use() and app.configure() here...

// Load in the routes by calling the function we
// exported in routes.js
routes(app,io);
// Similarly with our realtime module.
realtime(io);

server.listen(8080);

这些都是在我的脑海中写下来的,只需要对各种API的文档进行最少的检查,但我希望它能够为您从应用程序中提取模块提供种子.
