Express Js

What is Express Js?

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.

With a myriad of HTTP utility methods and middleware at your disposal, creating a robust API is quick and easy.

Express provides a thin layer of fundamental web application features, without obscuring Node.js features that you know and love.
