Nodemon VS PM

What is Nodemon? Nodemon is a command-line tool that helps with the speedy development of Node.js applications. It monitors your project directory and automatically restarts your node application when it detects any changes. This means that you do not have to stop and restart your applications in order for your changes to take effect. You can simply write code, and test your application a few seconds later. How to start a node application with Nodemon? To install nodemon locally, we can run the following in the Terminal npm install nodemon Nodemon serves as a replacement for node, and does not require any code […]

Load Balancing Algorithms in Node.js

Load balancing is crucial for distributing incoming network traffic across multiple servers, ensuring no single server is overwhelmed. In this article, we’ll delve into three popular load-balancing algorithms, their implementation in Node.js, and the scenarios where each is most beneficial. 1. Round Robin Round Robin is the most straightforward load-balancing algorithm. Each server is selected in turns, looping back to the first server after the last. The benefit of Round Robin is that it is simple and predictable. You don’t need to keep track of server load or number of simultaneous connections etc. Scenarios for Use: 2. Least Connections The […]

Role-Based Access Control in Nodejs

Introduction This article will help you set up RBAC i.e Role-Based Access Control in your node application. RBAC allows us to provide permission to users based on their roles. We are often required to provide different roles to users to improve the security of the application. Thus, we will be discussing an application with 3 roles for the user — client, moderator and admin. The user with the admin role will have access to a special route which will allow him to change roles of other users as well as view profiles of all the users. Pre-Requisites Following are the […]

Advance Building a Load Balancer using Node JS + Express

Building a Scalable Load Balancer with Node.js and Express Load balancing is a critical component of any scalable web application. It helps distribute incoming client requests evenly across multiple backend servers, optimizing resource utilization and ensuring high availability. In this comprehensive tutorial, we will build a highly flexible load balancer using Node.js and Express that can handle multiple heterogeneous backend servers. Overview Here are the core features we will implement in our load balancer: We will use a modular design pattern to make it easy to modify or extend components later. Our load balancer will run as a standalone Node.js […]

NestJS vs Go: Performance comparison for JWT verify and MySQL query

Introduction After publishing a record number of articles on comparing performance of various technologies like Node.js, Deno, Bun, Rust, Go, Spring, Python, etc. for a simple hello world case, I consistently got comments that the articles were good, but weren’t applicable directly for real-world use cases. I was asked to do the same for more ‘real-world’ cases. The articles also (and still) attracted a record number of views. However, the point was well taken. Hello world was the best starting point, but definitely not a ‘real-world’ case. Real-world use case This article is a part of the series where I’m […]

5 Common Server Vulnerabilities with Node.js

Introduction Node.js is a powerful and widely-used JavaScript runtime environment for building server-side applications. However, like any other software, Node has its own set of vulnerabilities that can lead to security issues if not properly addressed. Please do note that these vulnerabilities are not unique to Node, they can be found in every backend programming language. This article will explore 5 common vulnerabilities: 1. Injection Vulnerabilities Node applications are vulnerable to injection attacks, such as SQL injection, NoSQL injection, and Command Injection. These types of attacks occur when an attacker inputs malicious code into a vulnerable application and the application executes it. An injection vulnerability […]

Configure ESLint, Prettier, and Flow in VS Code for React Development

This short guide will provide you a consistent and reusable development workflow for all React Native projects. The more effort you put into writing quality code, the less time you spend on debugging. You can increase your code quality and reduce the time spent on debugging with a consistent development workflow. In this guide I will show you how to configure your editor to handle your code formatting, linting, and type checking. Test Driven Development and a preconfigured build configuration are recommended. I won’t go into much detail on either of these. I recommend create-react-app for the web and using the React Native […]
