Express.js is a fast, unopinionated, and minimalist web framework for Node.js. It provides a robust set of features for building web applications and APIs, including routing, middleware support, template engines, and HTTP utility methods. Express.js has become the de facto standard for Node.js web development due to its simplicity, flexibility, and extensive middleware ecosystem. It allows developers to create everything from simple REST APIs to complex web applications with ease. Express.js is designed to be minimal and flexible, making it an excellent choice for developers who want control over their application architecture while benefiting from a solid foundation.
