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'}

我写了一个小插件来做这件事!我厌倦了一遍又一遍地写同样的代码。

希望能有所帮助。

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);

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;

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);
    });
}
