Express Middleware

Middleware is a function with access to the request object (req), the response object (res), and the next middleware in line in the request-response cycle of an Express application, commonly denoted by a variable named next. Middleware can:

Execute any code.
Make changes to the request and the response objects.
End the request-response cycle.
Call the next middleware in the stack.

An Express application can use the following kinds of middleware:

You *mount* the middleware using 'use':

app.use(function (req, res, next) { console.log('Time:', Date.now()); next(); });
