Introduction One of the core features of any backend application is the ability to interact with the file system. Whether you’re creating log files, managing data, or serving static content, handling files effectively is crucial. In Node.js, the fs (File System) module provides a powerful set of tools that allow developers to interact with the…

Introduction Node.js is a powerful platform for building scalable and efficient applications, largely due to its vast ecosystem of built-in libraries and modules. These core modules are prepackaged with Node.js and provide essential functionality to help developers tackle common programming challenges. Core modules are designed to handle tasks such as working with files, managing HTTP…

What Are Modules in Node.js? In Node.js, modules are individual units of code that can be imported and exported between files. They are the building blocks of Node.js applications and allow developers to organize and structure their code in a modular and maintainable way. Each module in Node.js is essentially a self-contained piece of functionality…

Introduction In today’s rapidly advancing world of web development, JavaScript is no longer confined to running in web browsers. With the advent of Node.js, JavaScript has found a new environment outside of the browser—on the server. Node.js is an open-source, event-driven runtime environment that allows developers to execute JavaScript code on the server side, enabling…

Introduction Node.js has emerged as a powerful platform for server-side development, bringing JavaScript—once confined to the browser—into the backend realm. It is an open-source, cross-platform runtime environment for executing JavaScript code outside of the browser. Since its inception in 2009, Node.js has gained immense popularity, particularly for building fast, scalable, and high-performance web applications. In…

Introduction One of the key features that make Node.js such a versatile and powerful environment for developing server-side applications is its unique architecture and set of built-in modules. A critical component of this system is the global object, which functions in a similar way to the window object in browsers, but within the Node.js runtime…

Node.js has revolutionized web development by enabling JavaScript to be used on both the client and server sides. If you’re new to Node.js, writing your first script is the first step in unlocking the power of this runtime environment. Whether you’re building an API, a web server, or just learning the fundamentals of asynchronous programming,…

Introduction In the world of JavaScript development, npm (Node Package Manager) stands as one of the most essential tools for developers working with Node.js and JavaScript-based applications. It is a command-line tool used to manage packages or libraries in a Node.js environment, allowing developers to easily install, update, and manage external dependencies. The npm ecosystem…

Introduction Installing Node.js is the first step to harnessing the full power of JavaScript beyond the browser. Once Node.js is installed, it’s important to verify that the installation was successful and that you have the correct versions of Node.js and npm (Node Package Manager). Verifying your installation ensures that everything is set up properly before…

Introduction Node.js is one of the most powerful and popular technologies for building scalable, fast, and efficient web applications. It allows developers to run JavaScript on the server side, enabling full-stack JavaScript development. However, before you can start developing with Node.js, the first step is to install it on your computer. The process of installing…
