What is middleware in Node JS?

Question

Can anyone tell me what is middleware in Node JS?

Answer 1

Middleware functions have access and modify the request and response objects in the application’s request-response cycle.

A middleware function can perform the following tasks:

• It can execute any code.
• It can make modifications to the request and the response objects.
• It can end the request-response cycle.
• It can call the next middleware function in the stack.
