Middleware is code that runs between receiving a request and sending a response. It's the backbone of request processing in web applications.

Implementation Note: The patterns and code examples below represent one proven approach to building middleware systems. Middleware patterns vary—Express uses a callback-based approach, Koa uses async/await with context, and H3 uses a minimal event-based system. The direction shown here follows the modern async/await pattern with composability. Adapt based on your framework's async model, error handling strategy, a...
