Nodejs is actually a JavaScript execution environment.To create a new file Server.js, enter the following code:var http = require (' http 'var server = Http.createserver (function(req, res) { Res.writehead ($, {' Content-type ': ' Text/plain '}); Res.end (' Hello world\n ');}); Server.listen (1337, ' 127.0.0.1 '); Console.log (' Server running at http://127.0.0.1:1337 ');The console goes to the direct

1. Prepare a folder for the project2. Create a server.js file under the root directory3. The file code is as followsvar http = require ("http");Http.createserver (function (request,response) {Response.writehead (200,{' content-type ': ' Text/plain ');Response.End ("Hello world\n")}). Listen (8080);Console.log ("Server running at http://127.0.0.1:8080/")4. Open the project directory with the command line execute the

Note: 1. To save the hello. js program file as a UTF-8 hello. js file, use notepad. 2. Chinese encoding must be supported in the output webpage. Res. write (' Now we use node. js to create a small www server. Console. log ('hello') console. log ('Hello % s-> % d
