尝试使用快速加载和expression4

我开始在NodeJS，但我的代码有一个问题。 我将显示代码。

我需要以MVC模式加载应用程序，我正在使用express-load ，但是当我创build加载顺序时会出错。

app.js（重要部分）

 var load = require('express-load'); ... load('models').then('controllers').then('routes').into(app); 

控制器/ home.js

 module.exports = function(app){ var HomeController = { index: function(req,res) { res.render('home/index'); } } return HomeController; } 

路线/ home.js

 module.exports = function(app){ var home = app.controllers.home; app.get('/home',home.index); } 

错误

因为甚至没有使用模型，修改了load

 load('controllers').then('routes').into(app); 

控制器和路由存在，但给出错误。 我想以MVC模式加载我的应用程序。

Answer 1

删除home.js以外的路由文件夹下的所有文件。 我认为你有默认的索引和用户路由文件，造成这些问题。

您可以从index.js和users.js文件中删除以下行，以避免出现问题。

 var express = require('express'); var router = express.Router(); 

对不起我的英语不好。
