Express

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for building web and mobile applications. It simplifies the process of creating server-side applications by handling routing, middleware, and HTTP requests/responses, allowing developers to focus on business logic.

Also known as: Express.js, ExpressJS, Node Express, Express Framework, Express Node

Why learn Express?

Developers should learn Express when building web servers, APIs, or full-stack applications with Node.js, as it is the de facto standard for Node.js web development. It is particularly useful for creating RESTful APIs, single-page applications, and microservices due to its lightweight nature and extensive middleware ecosystem.
