It is flexible as there are numerous modules available on npm, which can be directly plugged into Express.Įxpress was developed by TJ Holowaychuk and is maintained by the Node.js foundation and numerous open source contributors. It provides us the tools that are required to build our app.

What is Express?Įxpress provides a minimal interface to build our applications. With ExpressJS, you need not worry about low level protocols, processes, etc.
