79-80: Signature update for Delete.No issues identified. This change aligns with the overall rename effort.
85-86: Signature update for Connect.Straightforward parameter renaming. The method logic appears unaffected.
91-92: Signature update for Options.Continues the naming consistency. Good to see the uniform approach maintained.
97-98: Signature update for Trace.Use of
handlersclarifies the function intent. No additional concerns.
103-104: Signature update for Patch.No issues. This renaming step is consistent with the others.
108-109: Add method usage changed.Applying

23-23: Add method doc updated.Renaming the variadic parameter to
handlerskeeps the documentation consistent with the implementation code.
27-27: All method doc updated.The revised signature highlights that multiple handlers can be chained, which aligns with the rest of the doc changes.
50-52: Use method doc updated.Switching from
middlewares ...Handlertohandlers ...Handlerclarifies that any function can be included, whether it's a middleware or a final handler.docs/api/app.md (1)
137-150: Update variadic parameter naming in Register interface.
The updated documentation correctly reflects the API change where the parameter formerly namedmiddleware ...Handlerhas been renamed tohandlers ...Handler. This change enhances clarity and maintains consistency with the updated routing handler registration logic.

🧩 Analysis chain
Add test coverage for the missing handler validation.
The static analysis indicates that the validation code is not covered by tests. Please add test cases to verify this validation.
🏁 Script executed:
#!/bin/bash
# Description: Check if there are any existing tests for missing handler validation

Action Required: Add Tests for Missing Handler Validation
The current code in router.go (lines 324-326) triggers a panic when no handler/middleware is provided:
if len(handlers) == 0 && !isMount {
panic(fmt.Sprintf("missing handler/middleware in route: %s\n", pathRaw))
}However, our search confirms that there are no tests covering this scenario. Please add test cases that explicitly:
- Invoke the route setup with an empty handler list.
- Assert that the function panics with the expected error message.
