Express JS & Nunjucks Tutorials : Part 2 Using Express Middleware
In this video we'll be looking into the use case of express middleware.
Express is a routing and middleware web framework that has minimal functionality of its own: An Express application is essentially a series of middleware function calls.
Middleware functions are functions that have access to the request object (req), the response object (res), and the next middleware function in the application’s request-response cycle. The next middleware function is commonly denoted by a variable named next.
Middleware functions can perform the following tasks:
Execute any code.
Make changes to the request and the response objects.
End the request-response cycle.
Call the next middleware function in the stack.
Topics covered :
1. Express Middleware usage
2. Performing route using app.use("") method.
