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;

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}]
};   

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'}

如果你想把路由放在一个单独的文件中，例如routes.js，你可以这样创建routes.js文件:

module.exports = function(app){

    app.get('/login', function(req, res){
        res.render('login', {
            title: 'Express Login'
        });
    });

    //other routes..
}

然后你可以从app.js中以这样的方式传递app对象:

require('./routes')(app);

看看这些例子:https://github.com/visionmedia/express/tree/master/examples/route-separation

基于@ShadowCloud的例子，我能够在子目录中动态地包含所有路由。

路线/ index.js

var fs = require('fs');

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

然后将路由文件放在routes目录中，如下所示:

路线/ test1.js

module.exports = function(app){

    app.get('/test1/', function(req, res){
        //...
    });

    //other routes..
}

根据需要重复多次，最后在app.js中放置

require('./routes')(app);

如果你使用express-4。使用TypeScript和ES6，这将是最好的模板使用:

登录src /火/ ts。

import express, { Router, Request, Response } from "express";

const router: Router = express.Router();
// POST /user/signin
router.post('/signin', async (req: Request, res: Response) => {
    try {
        res.send('OK');
    } catch (e) {
        res.status(500).send(e.toString());
    }
});

export default router;

src / app.ts

import express, { Request, Response } from "express";
import compression from "compression";  // compresses requests
import expressValidator from "express-validator";
import bodyParser from "body-parser";
import login from './api/login';

const app = express();

app.use(compression());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(expressValidator());

app.get('/public/hc', (req: Request, res: Response) => {
  res.send('OK');
});

app.use('/user', login);

app.listen(8080, () => {
    console.log("Press CTRL-C to stop\n");
});

比使用var和module.exports干净多了。
