Types

A middleware function. Runs for each request.

Return void to continue to the next middleware. Return a Response to short-circuit the pipeline. Throw an Error to signal a failure.

What modules register as middleware — either a class or a function.

A handler-scoped middleware function. Runs after the dispatcher has resolved the handler, so rc.handler is guaranteed to be present.

Same short-circuit semantics as BaseMiddlewareFn.

What modules register as handler-scoped middleware — either a class or a function. Registered via ModuleSettings.middleware.handler or attached directly to a handler via @WithMiddleware.

Callback invoked before the decorated method runs. Receives the RequestContext for the current request. Throw to abort the call.
