What is Express.js?

Definition

Express.js is a fast, unopinionated, minimalist web framework for Node.js. It provides a robust set of features to develop web and mobile applications, acting as a thin layer on top of Node.js's built-in HTTP server capabilities. By hiding the complex low-level details of raw Node.js HTTP servers, Express makes it incredibly easy to define routes, parse payloads, and handle HTTP requests and responses.
