Node.js HTTP Module

Node.js HTTP Module

In this tutorial, we will learn about Node.js HTTP module and understand how out code working that we have written in Getting started with node.js.

Node.js has a built-in module called HTTP, which allows Node.js to transfer data over the http. To include the HTTP module, use the require() function.
 var http = require('http');

Node.js as a Web Server

The HTTP module can create an HTTP server that listens to server ports and gives a response back to the client. we used createServer() method to create an HTTP server.
 var http = require('http');  
   
 //create a server object:  
 http.createServer(function (req, res) {  
  res.write('Hello World!'); //write a response to the client  
  res.end(); //end the response  
 }).listen(3000); //the server object listens on port 3000

OFFSET in Computer Science

OFFSET in Computer Science In the post, We will understand what is the meaning of OFFSET in computer science with an example. In computer science offset comes picture at may place like packing a data structure, encoding the data etc in some standard protocol so that other parties can deserialise it and understand the data. We will understand its important how does it work with example. suppose we have a data structure for a student like { name:string[20] roll: int[4] course: string[25] batch: int[4] } We want to serialise below student data  { name:"Amit Gupta" roll: 1234 course:Computer Science" batch: 2018 } Our protocol follow the rule that we will insert a value and if space will remain empty we will fill it with $ for example length of "Amit Gupta" is 10 but standard size is 20 so will fill 10 $ after "Amit Gupta". So serialisation of above data will be Amit Gupta$$$$$$$$$$1234Computer Sc...

Variable In C

Variable Like any other programming language in C programming language, we use a variable to store value, a value is any data like a number a or a character. In this post, we will learn about datatype of C programming language. Type Of Variable In C In this section, we will discuss how to store the following type of variable in C How to store an integer in C? How to store a float in C? How to store a double in C? How to store a long in C? How to store a character in C? As we already discussed that variable used to store data so that we can use it of other computation, for example, suppose we want to calculate the sum of two number then we have to store these two numbers first only after that we can use these two stored value to compute the sum. The entity that used to store a value called variable. What does it mean is suppose we tell a variable to store a number whose value is 5, the variable will place this number 5 in memory and we can variable in...

Clique in Graph

Clique in Graph In this tutorial, we will learn about the clique in the graph theory. Clique In graph theory, a clique is a subset of vertices of an undirected graph such that every two distinct vertices in the clique are adjacent.
