index.js

const express = require("express");
const app = express();
const http = require('http');
const server = http.createServer(app).listen(3000);
const router = (global.router = (express.Router()));
app.use('/books', require('./routes/books'))
app.use('/users', require('./routes/users'))
app.use(router);

路线/ users.js

const router = global.router
router.get('/', (req, res) => {
    res.jsonp({name: 'John Smith'})
}

module.exports = router

路线/ books.js

const router = global.router
router.get('/', (req, res) => {
    res.jsonp({name: 'Dreams from My Father by Barack Obama'})
}

module.exports = router

如果您的服务器在本地运行(http://localhost:3000)，那么

// Users
curl --request GET 'localhost:3000/users' => {name: 'John Smith'}

// Books
curl --request GET 'localhost:3000/books' => {name: 'Dreams from My Father by Barack Obama'}

所有这些答案的一个调整:

var routes = fs.readdirSync('routes')
      .filter(function(v){
         return (/.js$/).test(v);
      });

只需使用正则表达式通过测试数组中的每个文件进行筛选。它不是递归的，但它会过滤掉不以.js结尾的文件夹

在前面答案的基础上，这个版本的routes/index.js将忽略任何以.js(和它本身)结尾的文件。

var fs = require('fs');

module.exports = function(app) {
    fs.readdirSync(__dirname).forEach(function(file) {
        if (file === "index.js" || file.substr(file.lastIndexOf('.') + 1) !== 'js')
            return;
        var name = file.substr(0, file.indexOf('.'));
        require('./' + name)(app);
    });
}

您可以将所有路由函数放在其他文件(模块)中，并将其链接到主服务器文件。 在main express文件中，添加一个将模块链接到服务器的函数:

   function link_routes(app, route_collection){
       route_collection['get'].forEach(route => app.get(route.path, route.func));
       route_collection['post'].forEach(route => app.post(route.path, route.func));
       route_collection['delete'].forEach(route => app.delete(route.path, route.func));
       route_collection['put'].forEach(route => app.put(route.path, route.func));
   }

并为每个路由模型调用该函数:

link_routes(app, require('./login.js'))

在模块文件(例如- login.js文件)中，像往常一样定义函数:

const login_screen = (req, res) => {
    res.sendFile(`${__dirname}/pages/login.html`);
};

const forgot_password = (req, res) => {
    console.log('we will reset the password here')
}

然后用request方法导出它作为键，值是一个对象数组，每个对象都有路径和功能键。

module.exports = {
   get: [{path:'/',func:login_screen}, {...} ],
   post: [{path:'/login:forgotPassword', func:forgot_password}]
};   

我试图用“express”更新这个答案:“^4.16.3”。这个答案与ShortRound1911的答案相似。

server.js:

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const db = require('./src/config/db');
const routes = require('./src/routes');
const port = 3001;

const app = new express();

//...use body-parser
app.use(bodyParser.urlencoded({ extended: true }));

//...fire connection
mongoose.connect(db.url, (err, database) => {
  if (err) return console.log(err);

  //...fire the routes
  app.use('/', routes);

  app.listen(port, () => {
    console.log('we are live on ' + port);
  });
});

/ src /线路/ index.js:

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

const siswaRoute = require('./siswa_route');

app.get('/', (req, res) => {
  res.json({item: 'Welcome ini separated page...'});
})
.use('/siswa', siswaRoute);

module.exports = app;

/ src /线路/ siswa_route.js:

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

app.get('/', (req, res) => {
  res.json({item: 'Siswa page...'});
});

module.exports = app;

如果你想要一个单独的.js文件来更好地组织你的路由，只需在app.js文件中创建一个变量，指向它在文件系统中的位置:

var wf = require(./routes/wf);

然后,

app.get('/wf', wf.foo );

其中.foo是wf.js文件中声明的某个函数。如

// wf.js file 
exports.foo = function(req,res){

          console.log(` request object is ${req}, response object is ${res} `);

}
