Express.js

Express.js is a fast, minimalist web application framework for Node.js, designed to simplify the development of server-side applications. It provides a robust set of features for building web and mobile applications, including routing, middleware integration, and HTTP utility methods. Express.js allows developers to handle requests, define routes, and serve static files with ease, making it a popular choice for creating RESTful APIs and web services. Its flexible architecture enables the addition of numerous plugins and extensions, enhancing its functionality to meet specific needs. By abstracting much of the complexity of Node.js, Express.js streamlines the development process, allowing developers to focus on building efficient and scalable applications. Its simplicity, performance, and vast ecosystem have made Express.js a cornerstone in the Node.js community.
