In Node.js, NODE_ENV is an environment variable used to define the current environment in which the Node.js application is running. It plays a crucial role in configuring the behavior of the application based on different environments such as development, staging, and production. This article delves into the significance of NODE_ENV, its usage, and best practices for managing environments in Node.js applications....

A JSON Web Token (JWT) is a JSON object utilized to securely transmit information between two parties over the web. Primarily employed in authentication systems, JWTs can also facilitate secure data exchange. These tokens enhance security by incorporating encryption, and for added protection, a signature can be appended. A JWT comprises a header JSON, a payload JSON, and an optional signature. Each of these components is concatenated with a period (“.”) separator....

There are so many ways to store data for better understanding for individual purposes, in few cases, JSON files will be more suitable in few cases, CSV files, and there are also lots of other types as well like XML, etc. In this article, we will convert the JSON file data into CSV file data and also display that through Node.js....

We know NodeJS application is single-threaded. Say, if processing involves request A that takes 10 seconds, it does not mean that a request which comes after this request needs to wait 10 seconds to start processing because NodeJS event loops are only single-threaded. The entire NodeJS architecture is not single-threaded....

The current date can be formatted by using Nodejs modules like Date Object or libraries like moment.js....

Node.js is a powerful platform for building server-side applications and returning JSON data is a common task in web development, especially when building APIs. JSON stands for JavaScript Object Notation. It is one of the most widely used formats for exchanging information across applications. Node.js supports various frameworks that help to make the processes smoother. The following ways cover how to return JSON data in our application from Node.js. This article will guide you through the process of setting up a simple Node.js server that returns JSON data in response to client requests....

Node.js with the help of Express, supports web page routing. This means that when the client makes different requests, the application is routed to different web pages depending upon the request made and the routing methods defined. To learn more about Node.js routing and its implementation, refer this article....

Node.js relies on various dependencies under the hood for providing various features....

In Node.js, particularly when working with the Express framework, middleware functions play a crucial role in handling requests. Two commonly used patterns within these middleware functions are next() and return next(). Understanding when and how to use these can significantly affect the flow and functionality of your application....
