feat: course category taxonomy with CodeRabbit fixes - #475
Conversation
- Add lib/categories.js as single source of truth for 31 Islamic categories (slug, label, group, description, icon) across 6 groups. Includes resolveSlug() with legacy-value fallback + console.warn, getCategoryCounts() for client-side counts (backend-ready), getGroupedCategories(), and an islamicCategoriesCompat shim. - Fix ComboBox.jsx: remove internal value state bug; now fully controlled by the category prop; imports from lib/categories.js. - Update courseCard.jsx: category badge links to the category landing page via resolveSlug(); unknown/legacy categories render as a plain decorative badge (no crash). - Update courses page with URL-driven filters: horizontally scrollable category chips, text search, sort (newest/price/rating), all state persisted in ?category=&sort=&q= query params; survives refresh. - Add /dashboard/courses/categories: browsable hub showing all 6 groups and 31 category cards with live course counts; empty categories are de-emphasised (not hidden). - Add /dashboard/courses/category/[slug]: landing page with hero, breadcrumb, filtered & sorted course grid, empty state with educator CTA, not-found state for unknown slugs. Closes Deen-Bridge#113
- Guard _bySlug and _labelToSlug lookups with Object.hasOwn to reject inherited prototype keys (constructor, __proto__) - Fix resolveSlug: empty string now returns null before any lookup - Fix resolveSlug: partial matching now returns slug only on unique match (prevents ambiguous values like 'Islamic' resolving to wrong category) - Fix fetchCourses error handling: failures now surface to error state instead of silently collapsing to empty list in categories hub, category landing, and main courses page (bookmark branch unchanged) - Rebased onto latest upstream/dev to resolve merge conflicts

WalkthroughAdds a shared category taxonomy, a grouped category hub, dynamic category landing pages, course sorting and filtering, navigable category badges, and explicit fetch error handling. ChangesCourse category discovery
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to The new category experience is not merge-ready: the hub and category pages can fail at runtime, existing Seerah courses can disappear from category navigation, and fetch outages can appear as empty catalogs; the new dashboard route may also bypass the protection used by existing dashboard pages until authentication and server-side authorization are confirmed.

Expose fetch failures separately from an empty course catalog.
fetchCourses() catches request errors and returns []. An empty array is truthy, so every new if (!data) guard accepts the failure and renders an empty state instead of NetworkErrorComp. Make fetchCourses() reject on request failure, or return an explicit result status.

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win
Use fields from the category group object.
CATEGORY_GROUPS contains objects, but this code compares c.group to the whole object and renders {group}. The comparison produces no category cards. Rendering the object throws and prevents the hub from loading. Use group.categories, group.id, and group.label.
Proposed fix
{CATEGORY_GROUPS.map((group) => {
- const groupCategories = CATEGORIES.filter(
- (c) => c.group === group
- );
+ const groupCategories = group.categories;
return (
- <section key={group}>
+ <section key={group.id}>
<h2>
- {group}
+ {group.label}

Render each Lucide icon as a JSX element.
The taxonomy stores Lucide component references. Rendering {cat.icon} or {category.icon} passes a component definition as a child, which React rejects. Assign the value to a capitalized local such as CategoryIcon, then render <CategoryIcon />.

Preserve the legacy Seerah category value.
Courses stored with Seerah (Life of the Prophet ﷺ) no longer resolve. resolveSlug() returns null, so cards lose category navigation and the category page excludes these courses. Add a legacy alias or apply the existing parenthetical-label normalization before matching.
