Settings Tabs Implementation - Summary

Project: StreamPay Frontend - GrantFox Campaign

Date: June 29, 2026
Objective: Convert Settings sections into accessible tabs
Status: ✅ COMPLETE

Changes Overview

1. New Accessible Tabs Component

File: app/components/Tabs.tsx

A production-ready, fully accessible React component implementing the WAI-ARIA Tab Pattern.

Key Features:

  • Full keyboard navigation (Arrow keys, Home/End)
  • ARIA roles and attributes (tablist, tab, tabpanel)
  • Focus management and visual indicators
  • Callback support for state changes
  • TypeScript types included

Test Coverage: 26 tests, all passing ✅

2. Refactored Settings Architecture

Settings Main Page

File: app/settings/page.tsx

Now uses the Tabs component to organize settings into two main tabs:

  1. Appearance - Theme selection
  2. Notifications - Full notification preferences UI

Benefits:

  • Single-page interface eliminates context switching
  • Faster tab navigation (no page reloads)
  • Better state management within page

Notification Settings Component

File: app/components/settings/NotificationSettings.tsx

Extracted and reusable notification preferences UI supporting:

  • Push notification opt-in/fallback email
  • Money Movement alerts (4 notification types)
  • Product Information alerts (2 notification types)
  • Save callback integration

Reusability: Can be embedded in tabs or standalone pages

Notifications Page

File: app/settings/notifications/page.tsx

Updated to use the new NotificationSettings component, reducing code duplication and improving maintainability.

3. CSS Styling

File: app/globals.css (lines 473-521)

Added comprehensive tab styling with:

  • Flex-based layout for responsive design
  • Hover states and active indicators
  • Focus-visible styling (outline, offset)
  • Smooth fade-in animations
  • Respects prefers-reduced-motion user preference

CSS Classes:

  • .tabs - Root container
  • .tabs__header - Tab button container
  • .tabs__button - Individual tab button
  • .tabs__button--active - Active tab state
  • .tabs__content - Panel content area
