The Complete Strapi™ Course with Plugins and Deployment - Middleware

The video tutorial explains the concept of middleware in Strapi, detailing how middleware functions are executed in the request-response flow. It distinguishes between core and custom middleware, emphasizing the importance of registering custom middleware in the configuration file. The tutorial provides a step-by-step guide to creating a custom middleware that adds a timer header to responses, demonstrating how to test and determine the execution order of middleware functions. The lesson concludes by highlighting the transition to core functions like controllers and services.

What is the primary role of middleware in the request-response flow?

• To handle core business logic

• To alter the request-response flow with additional functionality

• To manage database connections

• To render the user interface

Where must all Strapi middleware functions be registered and exported?

• In the main server file

• In the database schema

• In the user interface module

• In the configure folder

What is the difference between core middleware and root middleware?

• Core middleware is for specific routes, root middleware is global

• Core middleware is global, root middleware is for specific routes

• Core middleware is for user authentication, root middleware is for data validation

• Core middleware handles errors, root middleware handles requests

What must be done after creating a custom middleware to ensure it is applied?

• Register it with the user interface

• Compile it with the application

• Include it in the configuration file

• Add it to the database

What does the example middleware function add to the response?

• A custom error message

• A custom timer header

• A user authentication token

• A data validation report

Why is the order of middleware execution important?

• It changes the database schema

• It affects the user interface

• It determines the sequence of request processing

• It alters the server configuration

What is observed when testing the custom middleware?

• A change in the database schema

• A new user interface element

• An error in the server log

• The addition of a custom header in the response
