express

• Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.
• APIs With a myriad of HTTP utility methods and middleware at your disposal, creating a robust API is quick and easy.
• Performance Express provides a thin layer of fundamental web application features, without obscuring Node.js features that you know and love.

bodyParser

• Node.js body parsing middleware.
• Parse incoming request bodies in a middleware before your handlers, available under the req.body property.
• As req.body’s shape is based on user-controlled input, all properties and values in this object are untrusted and should be validated before trusting. For example, req.body.foo.toString() may fail in multiple ways, for example the foo property may not be there or may not be a string, and toString may not be a function and instead a string or other user input.
