34-34: Verify keyboard navigation behavior
Since this is a navigation component, we should ensure it maintains proper keyboard navigation functionality.
Let's check for keyboard event handling in related components:
✅ Verification successful
Keyboard navigation implementation is properly handled
The component has appropriate keyboard event handlers and accessibility attributes:
- Implements all necessary keyboard events (
keydown,keypress,keyup) - Correctly sets
role="link"for anchor elements - Properly forwards all events via
$$restProps - Works in conjunction with other navbar components that also implement proper ARIA roles (e.g.,
role="button"withtabindex="0")
🏁 Scripts executed
The following scripts were executed for the analysis:

#!/bin/bash
# Description: Check for keyboard navigation handling in navbar components
# Look for keyboard event handlers in navbar components
echo "Checking for keyboard navigation handlers in navbar components..."
rg -t svelte "on:key" src/lib/navbar/
# Look for accessibility-related tests

🛠️ Refactor suggestion
The role attribute change needs refinement
While the intention to improve accessibility is good, setting role="link" on an <a> element is redundant as anchor elements have an implicit link role. Additionally, we should consider adding more ARIA attributes for better accessibility.
Consider this implementation:
- <svelte:element this={href ? 'a' : 'div'} role={href ? 'link' : undefined} {href} {...$$restProps} on:blur on:change on:click on:focus on:keydown on:keypress on:keyup on:mouseenter on:mouseleave on:mouseover class={liClass}>
+ <svelte:element
+ this={href ? 'a' : 'div'}
+ role={href ? undefined : 'presentation'}
+ aria-current={active ? 'page' : undefined}
+ {href}
+ {...$$restProps}
+ on:blur
+ on:change
+ on:click
+ on:focus
+ on:keydown
+ on:keypress
+ on:keyup
+ on:mouseenter
+ on:mouseleave
+ on:mouseover
+ class={liClass}>Changes explained:
- Removed redundant
role="link"on anchor elements - Added
role="presentation"for div elements to indicate they're for layout - Added
aria-current="page"when the item is active - Improved code readability with multi-line formatting
Committable suggestion skipped: line range outside the PR's diff.

Setting the presentation role exactly like suggested would remove the link role again, which would not improve aria role coverage.

@LahTeuto, thank you for the clarification. You're absolutely right—setting role="presentation" would remove the link role and not improve ARIA role coverage. My apologies for the oversight.
I'll take this into account for future reviews.

Learning: When enhancing ARIA roles in Svelte components, avoid setting `role="presentation"` on elements that should retain the `link` role, as it can diminish ARIA role coverage and negatively affect accessibility.
Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.
📑 Description
This fixes a wrong aria role on the NavLi component resulting from a mixed up ternary operator.
