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

In today's fast-paced digital landscape, monitoring and optimizing the performance of Node.js applications is essential for delivering a seamless user experience.

PM2 provides a powerful and user-friendly web dashboard that allows you to monitor and control your Node.js applications with ease. In this blog post, we will explore how to leverage the PM2 Web Dashboard to monitor the performance of your Node.js applications effectively. By monitoring your Node.js applications using PM2 Web Dashboard, you gain valuable insights into critical metrics such as ... Read More

JSON  can be abbreviated as JavaScript Object Notation. It is a text-based file used for transferring and storing data in programming languages. It is supported by the python programming language using a built-in package namely JSON, Its text is given in the quoted string format in which contains a key and value within the curly braces{} as same as a dictionary. For using JSON in python, we have to import the JSON package in python script. JSON package provides several methods, among them one of the methods is dumps. This is used to convert the python tuple objects into ... Read More

In the rapidly evolving world of software development, the demand for scalable and maintainable applications has grown exponentially. To meet these challenges, microservices architecture has emerged as a popular solution. With the powerful combination of JavaScript and Node.js, developers have a flexible platform at their disposal for building microservices. In this article, we will delve deeper into the fundamentals of microservices, discuss key concepts, and provide practical code examples using JavaScript and Node.js. Understanding Microservices Architecture Microservices architecture is an architectural style in which applications are built as a collection of loosely coupled, independently deployable services. Each service is responsible ... 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 Nginx and Nodejs are two powerful tools that web developers use to build modern web applications. Nginx is a high-performance, open-source web server that can also function as a reverse proxy, caching server, load balancer, and more. Nodejs is a JavaScript runtime built on the Chrome V8 engine that allows developers to create fast and scalable network applications. The First Step: Installing and Configuring Nginx A Step-By-Step Guide to Installing Nginx on the Server Before you can configure Nginx as a reverse proxy for your Nodejs app, you need to install it. The installation process varies depending on your ... Read More

Overview of Node.js vs Java Java has been a long-standing favorite for programmers worldwide, while Node.js is a relatively new JavaScript runtime environment. This article delves into the differences between Node.js and Java and aims to provide a better understanding of both tools and their respective applications. While we may never settle the question of which is ultimately better, gaining insight into these powerful tools can help us make informed decisions about where and when to use them. What Is Node.js? In 2009, Ryan Dahl created Node.js, a cross-platform JavaScript (JS) runtime environment that enables developers to use JavaScript on ... 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
