Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. Created by TJ Holowaychuk and now maintained by the OpenJS Foundation, Express is the most widely used Node.js framework — the foundation of countless production APIs and the inspiration for almost every Node web framework that followed.
Its middleware-based architecture and minimal core have made it a pillar of the Node ecosystem since 2010.
Fast, unopinionated, minimalist web framework for Node.js. The de facto standard server framework.
