Why modules? JavaScript has evolved significantly over the years, and one of the critical areas of advancement is in how we manage and structure code using modules. Modules allow developers to break down complex applications into smaller, manageable parts, each with a specific purpose. There are several module systems that have been adopted over time, […]

The origins of the CommonJS module system CommonJS modules have been a foundational part of JavaScript, especially in Node.js, since before ES modules (ESM) were officially adopted. Designed to enable modular and maintainable code, CommonJS allows developers to import and export functionality across files using require and module.exports. This approach was crucial in shaping the […]

ESM, or ECMAScript Modules, is the official module system introduced in ECMAScript 6 (ES6), also known as ECMAScript 2015. ESM provides a native, standardized way to organize and structure code in JavaScript applications. Unlike CommonJS, which is synchronous and primarily used in Node.js, ESM is designed to work in both browser and server-side environments. Asynchronous […]

In the world of JavaScript, modularity is key to writing clean, maintainable, and scalable code. Two popular module formats that have emerged to facilitate this are AMD (Asynchronous Module Definition) and UMD (Universal Module Definition). These formats help developers manage dependencies and organize code in a modular fashion, making it easier to maintain large codebases. […]

Authentication vs. Authorization Authentication and authorization are foundational concepts in web security, yet they are often confused. Authentication is the process of verifying the identity of a user or system. In simpler terms, authentication ensures that the user is who they claim to be. Authorization, on the other hand, is the process of granting or […]

To better understand this article, I recommend reading my article on Authentication – Terms and concepts. A list of authentication mechanisms Given the rise of online threats and the increasing need for secure web applications, understanding various authentication mechanisms is crucial. Here’s an exhaustive list of commonly used methods in web technology, including older or […]
