In this article, we are going to discuss about “EADDRINUSE: address already in use” error in Node/Express. The “EADDRINUSE” error is a common issue encountered when developing Node.js applications with the Express framework. The line “address already in use” means the program wanted to use a particular “address” on your computer, but some other program […]

Whenever you are writing Node.js code on your system you have to run the “node index.js” command to execute the code written in the “index.js” file. Suppose you have made some changes to the “index.js” file and even after saving the file you will see there are no changes reflected in the application. After updating

Node.js is an open-source server-side runtime environment allowing developers to use JavaScript to create scalable, high-performance network applications. Unlike traditional web development, where JavaScript is primarily used on the client side, Node.js allows JavaScript code to be executed on the server. Node.js has undergone numerous version releases since its initial launch. The two major releases,

In Node.js we perform a lot of operations on data, which involves transferring data simultaneously from server to client and from client to server. There may be a possibility of a data breach while transferring data. To avoid this we can encrypt the data and then decrypt it later to get the same output ensuring

Many developers use MongoDB to store data when working with Node.js since NoSQL is considered best for it. But what if someone wants to work with SQL databases? The traditional option is to go with MySQL database, but it lacks many things and advanced operations. Here comes PostgreSQL. PostgreSQL is one of the popular MySQL

NVM stands for Node Version Manager. It is commonly used by developers working with Node.js. It allows developers to manage multiple versions of Node.js on a single machine. It enables you to easily switch between different Node.js versions to ensure compatibility with your projects. With NVM, you can install, uninstall, and switch between Node.js versions.

Node.js and MySQL are some of the necessary binding needed for any web application that is frequently used by Full Stack developers. MySQL is one of the most popular open-source databases in the world and is efficient as well. Almost every popular programming language like Java and PHP provides drivers to access and perform operations

NodeJS Query String module is used to parse and format the URL query strings. In this article, we will learn about different methods provided by this module but let’s first understand URLs and Query String. What is a URL?  URL stands for Uniform Resource Locator, the location of a given unique resource of a website,

A program usually executes line-by-line, meaning the function written first will execute first, and then the next function will execute. The problem arises when one function while executing blocks the execution of other functions. There may be some cases where this can be super annoying. For instance, suppose you are using a social media platform,

NodeJS is an open-source, cross-platform runtime environment that uses JavaScript for creating fast, data-intensive, and secure server-side applications.  These applications require some ways to store data in order to use them again. NodeJS supports all kinds of Databases, relational, and non-relational out of which MySQL can be the best choice. MySQL is a relational database
