hi
i have just started learning nodejs. i wrote this simple code
var http = require("http");
var fs=require('fs');
var wbsocket = ('ws');
http.createServer(function(req, res) {
res.write('2working');
}).listen(8889);
console.log('listing to port 8080');
and run in cmd node filename.js
in cmd doesnt give me any error and when i open webbrowser its continue loading and after 1mint says webpage not avilable.
so please tell me what i have wrong done ?
Hi, in order to write a response you have to send an header and then call end():
res.writeHead(200, {'Content-Type': 'text/html'});
res.write('2working');
res.end();
Also, probably mistype, on console log you wrote that it listens on port 8080, but it's executing on 8889.
Docs:
i tried also with res.send("hello world"); but wasnt working
Ok, does it work now?
Applying the end() method after you write the response body is mandatory. About the headers: if not defined, Node will set implicit headers, but you should always set a status [code|message] response:
By the way, you last attempt wasn't working for you because the send() method does not exists in the http module.
o yes it isnt node function... it was express module function..
is it neccessary to add
res.writeHead(200, {'Content-Type': 'text/html'});
?
As I wrote in previous post:
