As the consumption of the cyberspace and cloud-dependent applications proliferates, the gravity of safeguarding online data and transactions becomes more apparent. One of the most commonly employed methodologies for securing online communications is HTTPS, which provides an assurance that the information conveyed between the server and clients is ciphered and cannot be effortlessly intercepted by malevolent third parties. In this manuscript, we will probe into the process of building an HTTPS server with Node.js, an influential and adaptable platform for developing server-side applications using JavaScript. We will go over the fundamentals of SSL certificates, the essential components of an HTTPS ... Read More

Red Black Tree is a self-balancing binary search tree with additional properties that ensure a balanced tree structure and efficient operations. The delete operation in a Red Black Tree involves rearranging the tree and maintaining the Red Black Tree properties after removing a node. Here we are going to use three different methods:deleteNode method, delete method, and successor transplant method along with examples to elaborate the concept. In this article, The Golang program implements the deletion operation in a Red Black Tree data structure using Golang. Syntax func (t *RedBlackTree) Delete(key int) The Syntax "func (t *RedBlackTree) Delete(key int)" ... Read More

Introduction NodeJS is an open-source, cross-platform, server-side JavaScript runtime environment that allows developers to build scalable, high-performance applications. NodeJS is built on Chrome's V8 JavaScript engine and has become popular among developers due to its efficiency and ability to handle a large number of connections with ease. Frameworks, on the other hand, are pre-built software frameworks that provide a structure for developing applications. They offer a set of tools and guidelines that make it easier to build applications and help developers save time by providing pre-built components, libraries, and APIs. In this article, we will discuss the top NodeJS frameworks ... Read More

Socket.io is a popular JavaScript library that allows us to communicate between the server and the client. We can create an instance of socket.io on the client and server sides and listen to or emit the events from both sides. Also, we can listen to the event emitted from the server on multiple web clients. In real-time, we can use the socket.io library to create chat applications and online games requiring bi-direction communication. For example, if you have observed while playing chess or Ludo, it allows us to talk with our opponent. In this tutorial, we will learn to configure ... Read More

Introduction: What is Docker and Why Use it for Node.js? Docker is a containerization platform that lets you package your apps and dependencies into a self-contained environment. This means you can run your application in several environments without worrying about dependencies or setup difficulties. Utilizing Docker with Node.js can bring numerous advantages, particularly during the development and deployment stages of your project. You can use Docker to generate a Docker image of your Node.js application that includes all of the dependencies and configurations needed to run it. This image can then be readily distributed to additional developers or deployed ... Read More
