What is Middleware ? Why is Middleware important ?

What is Middleware?

• Middleware is a software layer that connects different parts of a system, like a bride.
• In web development, middleware sits between the client (user) and server (application), handling requests and responses.

Why is Middleware important?

• Helps manage common tasks like logging, authentication, and routing.
• Makes it easier to add features without changing the main application.
• Reusable and modular, can be used in different projects.

Types of Middleware:

• Application middleware: Manages application-specific tasks like routing and data transformation.
• Error Handling Middleware: Catches and handles errors, providing custom error messages.
• Authentication Middleware: Manages user login and access to secure resources.
• Logging Middleware: Records information for debugging and monitoring.
