NodeJS creates the simplest HTTP server and nodejs creates the server
☆Introduction
var http = require('http');http.createServer(function(request, response){ response.writeHead(200, { 'Content-Type': 'text-plain' }); response.end('Hello World\n');}).listen(8124);
There is a. createServer server method for the top-level http object.A server is created, and two events related to the server are created.Reque

Easy creation of nodejs servers (3): Code modularization and nodejs Modularization
Most node. js functional blocks exist in the form of modules.
Usually there is a unified entry index. js, and then different modules are called to complete the functions we need.
Let's take a look at how to turn server. js into a module for the index. js main file to be used.
Copy codeThe Code is as follows:Var http = require

We then rebuild the server so that the request processing program can return some meaningful information.
Let's take a look at how to implement it:
1. Let the request processing program directly return () the information they want to display to the user through the onRequest function.2. Let's start by asking the request handler to return the inform
The author of the well-known NodeJS framework Express, TJ Holowaychuk, tweeted and linked an article on Twitter, announcing the abandonment of NodeJS to Go.The reason he gives is that the go language and Rust, Julia, and so on are one of the many next-generation languages, although not the best language, but mature and robust enough to use the Go language to develop a better system, easier to maintain, erro

There are two ways for Nodejs to upload images: nodejs
Node: the first method for uploading images
1. first introduce the module "connect-multiparty ":"~ 1.2.5 ",
Add "connect-multiparty" to package. json ":"~ 1.2.5 ",
Switch to the project directory in the command, and run the npm command: npm installl;

NodeJs creates basic HTTP servers and nodejs creates servers.The content is simple, but the basics are written and shared with you. If you forget it, you can find it.
Create a server with the following code:
Var http = require ('http'); http. createServer (function (req, res) {res. writeHeader (200, {'content-type': 'text/html'}); res. write ('
Enter http: // 127.0.01: 3000 to access

A Preliminary Study on nodeJS and nodejs
I. Preface
In the "explore nodeJS" article, we have a general understanding of node, and finally through an example, we learned how to quickly start a simple server.
Today, I read this article again, and found that this article has a little more theoretical knowledge. It is suitable for beginners of node and has a fixed id

Next to the previous section, let's analyze the Code:

Next, we will call the function createServer provided by the http module.
This function will return an object, which has a method called listen. This method has a numeric
