express 的路由分离

在做大型项目是一般不会把路由写入server.js里,所以就有了路由分离

1.在项目目录下创建router文件夹

user.js

var express = require("express");
var router = express.Router();

var userRouter = router.get("/user", function(req,res) {
    res.send('user')
});

module.exports = userRouter

　　

root.js

var express = require("express");
var router = express.Router();

var rootRouter = router.get("/", function(req,res) {
    console.log('get')
    res.send('Root')
});

module.exports =rootRouter

　　

server.js

var express = require('express');
var userRouter = require('./router/user')
var rootRouter = require('./router/root')
var app = express();
//路由分离
app.use('/',rootRouter)
app.use('/',userRouter)

app.listen(8001)
console.log('listening to port 8001');
