route

以前，在app.js里可以写很多很多路由

app.get('/', function(req, res) {
  res.render('index', { title: 'Express' });
});
app.get('/2', function(req, res) {
  res.render('index', { title: 'Express' });
});
app.get('/3', function(req, res) {
  res.render('index', { title: 'Express' });
});
app.get('/4', function(req, res) {
  res.render('index', { title: 'Express' });
});
app.get('/5', function(req, res) {
  res.render('index', { title: 'Express' });
});

看着啥感觉？

路由其实就是分而治之的将具体的处理丢到单独文件中

写法

app.js

var routes = require('./routes/index');
var users = require('./routes/users');

挂载路由

app.use('/', routes);
app.use('/users', users);

具体写法

var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Express' });
});
module.exports = router;
