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。

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}]
};   

/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' });
    });
}

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);
    });
}
