Node.js Tutorial Node.js HTTP Module

What is Node js HTTP module?

The HTTP module allows Node.js to receive and transfer data via Hyper Text Transfer Protocol (HTTP).
The HTTP module creates an HTTP server that listens to server ports and gives a response back to the client.

Syntax:

var http = require('http');

We can create a HTTP server with the help of http.createServer() method.

 

Node.js as a Web Server

The following example demonstrates how to use the Node.js Http module to create a web server.

var http = require('http');

// Create a server
http.createServer((request, response)=>{

// Sends a chunk of the response body
response.write('Welcome to Nodejs page!');

//write a response to the client
response.end(); //end the response
}).listen(1443); // Server listening on port 1443

The function passed into the http.createServer() method, will be executed when someone tries to access the computer on port 1443.
Save the code above in a file called "demo_test_http.js", and initiate the file:

Initiate demo_test_http.js:
SELECT * FROM [Brazil Customers];

Add an HTTP Header

If the response from the HTTP server should be displayed as HTML, you should include an HTTP header with the correct content type:

var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write('Welcome to Nodejs page!');
res.end();
}).listen(80);

res.writeHead() method is the status code, 200 means that all is OK

 

Read the Query String

This object has a property called "url" which holds the part of the url that comes after the domain name:

Example: demo_test_http_url.js
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(req.url);
res.end();
}).listen(80);

Save the code above in a file called "demo_test_http_url.js" and initiate the file:
