One key aspect influencing the performance of network applications in Node.js is the TCP_NODELAY option. TCP_NODELAY is a key setting for improving data transmission in TCP connections. In the context of Node.js, we will explore its importance and learn how to use it to optimize data transfer. Through a straightforward program, we will demonstrate the […]

Do you know that _dirname in Node.js is responsible for representing the current directory of the script? Knowing the current directory is essential in Node.js applications for handling files, establishing reliable module paths, and maintaining a consistent file structure. So in this article, let’s try to get an in-depth knowledge of this variable and explore

UUIDs (Universally Unique Identifiers) play a vital role in modern software development. Creating Unique IDs is a standard need for many Node.js applications, from session management to database operations and for tracking inventory goods, upholding user accounts, and facilitating secure transactions are often included in software applications. The goal of this article is to give

Creating files is a fundamental task in Node.js development, allowing developers to generate new files dynamically for various purposes such as storing data, logging information, or serving as configuration files. The built-in fs module in Node.js provides functions for file operations, including creating, reading, and writing files. In this article, we will focus on creating

Node.js, a widely used JavaScript runtime, allows developers to build scalable and efficient server-side applications. However, as projects grow and dependencies increase, version conflicts may occur, complicating the development process. One common source of trouble is encountering an error message stating that “The engine node is incompatible with this module“. This error “The engine node

Express.js is one of the most popular Node.js frameworks developers use to create servers and web applications. Suppose you have set up a basic Express server and you want to send an HTML file on different route URL requests to make the server act as a web app, you can do so by implementing the

Executing JavaScript Files in Node.js is the core and important part of utilising the strength and adaptability of JavaScript programming. Node.js is the open-source back-end runtime environment for JavaScript applications. It has an extensive ecosystem of libraries and tools accessible via the Node Package Manager (NPM) to provide different functionalities. With Node.js it is easy

The forEach() method in Node.js is a basic tool for looping across arrays and performing an action on each element. This technique provides a clear and legible syntax while streamlining the process of applying actions to each element in an array. Node.js forEach() Method The forEach() method iterates over each element in an array and

The “ts-node” module allows developers to execute TypeScript files directly without requiring JavaScript compilation. It functions as a TypeScript execution and REPL (Read-Eval-Print Loop) for Node.js. TypeScript has been gaining in popularity but in order for the V8 engine to understand your TypeScript files, you must first compile them down into JavaScript and easy adjustment

Setting up the PATH environment variable for Node.js is not required, it simplifies the development process. You may still load each Node.js tool or module separately, but you won’t need to give their whole path when you set the PATH variable. This improvement makes the development process easier. This tutorial walks over the methods and
