• Source in this monorepo: packages/ui/src/components/scroll-area.tsx
• Place in your project: components/ui/scroll-area.tsx
• Required utility: lib/utils.ts (for cn helper)

2. Update the import paths to match your project structure.

Usage

import { ScrollArea } from "@hoag/ui/components/scroll-area";
 
export default function Demo() {
  return (
    <ScrollArea className="h-56 w-72 rounded-md border">
      <div className="space-y-2 p-4">
        {Array.from({ length: 12 }).map((_, index) => (
          <div key={index} className="rounded-md border px-3 py-2 text-sm">
            Activity item {index + 1}
          </div>
        ))}
      </div>
    </ScrollArea>
  );
}

Import

import { ScrollArea, ScrollBar } from "@hoag/ui/components/scroll-area";

    <ScrollArea className="h-56 w-72 rounded-md border">
      <div className="space-y-2 p-4">
        {Array.from({ length: 12 }).map((_, index) => (
          <div key={index} className="rounded-md border px-3 py-2 text-sm">
            Activity item {index + 1}
          </div>

Accessibility Checklist

• Verify semantic roles and ARIA attributes for interactive behavior.
• Keep keyboard navigation and focus visibility consistent in all states.
• Ensure color contrast meets accessibility requirements in light and dark themes.
• Provide screen reader context for dynamic state or content changes.

Testing Checklist

• Add render tests for default and key variant states.
• Add interaction tests for callbacks and state transitions.
• Add visual regression checks for responsive and theme variations.
• Cover edge states such as loading, empty, disabled, and error.

Production Tips

• Wrap component logic in feature-level abstractions for domain behavior.
• Keep visual variants centralized to avoid style drift across screens.
• Reuse a single import path strategy for simpler refactors.
• Mirror documented states in Storybook and QA checklists.

Named Exports

• ScrollArea
