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

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

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。

/routes文件夹中所有.js文件的完全递归路由，把它放在app.js中。

// Initialize ALL routes including subfolders
var fs = require('fs');
var path = require('path');

function recursiveRoutes(folderName) {
    fs.readdirSync(folderName).forEach(function(file) {

        var fullName = path.join(folderName, file);
        var stat = fs.lstatSync(fullName);

        if (stat.isDirectory()) {
            recursiveRoutes(fullName);
        } else if (file.toLowerCase().indexOf('.js')) {
            require('./' + fullName)(app);
            console.log("require('" + fullName + "')");
        }
    });
}
recursiveRoutes('routes'); // Initialize it

在/routes中你放入whatevername.js并像这样初始化你的路由:

module.exports = function(app) {
    app.get('/', function(req, res) {
        res.render('index', { title: 'index' });
    });

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

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'}
