前言 都说nodejs适合制作restful_API,因为它有异步处理能力,能吞吐更多的请求,这一点是大家都认可的.前不久我使用nodejs+express+postgresql搭建了一个restful中间处理平台,感觉express的api在代码量多的时候,显得凌乱.然后我开发了一个能够更好的组织express代码的module,借鉴了一些java中的想法.希望达到一种平衡,一种更优雅的方式组织代码. express 一个express项目的编码流程,大概是几步, 1.初始化app (expr

Installing Express Let's start building our new Express application by installing Express. Type the command that installs the latest version for the 4.9 branch. npm install express@4.9 The '@' symbol to tell the npm which express version you want to

router-level middleware works in the same way as application-level middleware, except it is bound to an instance of  express.Router(). code: var express = require('express'); var app = express(); var router = express.Router(); // a middleware functio

To skip the rest of the middleware functions from a router middleware stack, call next('route') to pass control to the next route. const express = require('express'); const app = express(); app.get('/user/:id', function (req, res, next) { ') next('ro

Route handlers enable you to define multiple routes for a path. The example below defines two routes for GET requests to the /user/:id path. The second route will not cause any problems, but it will never get called because the first route ends the r
